Recondition a Lead Acid Battery, Don’t Buy A New One

Lead acid batteries often die due to an accumulation of lead sulphate crystals on the plates inside the battery, fortunately, you can recondition your battery at home using inexpensive ingredients.

A battery is effectively a small chemical plant which stores energy in its plates. They are chemically charged with an electrolyte which is a mixture of distilled water and sulphuric acid. When the battery is discharged, the lead active material on the positive plates reacts with the sulphuric acid and produces lead sulphate. When the battery is charged, this process is reversed and the lead sulphate crystals react to form sulphuric acid again. The battery fails when there is an excess build up of lead sulphate crystals which then do not allow sulphuric acid to make contact with sections of the plate. These crystals harden and eventually cause a chemical imbalance in the electrolyte.

In most cases, hardened crystals can be removed using a solution of magnesium sulphate. This method doesn’t restore a battery back to original condition but it will restore it to around 70-80% of its original capacity and can be repeated, allowing you to get a few more years of use out of your battery without having to replace it.

How To Recondition Your Battery

Take the battery out of the vehicle, motorbike or scooter and put it onto a solid work bench.

Some battery’s cells are clearly visible on top of the battery and are sealed with screw in caps. Others, like mine, are protected by a “sealing” strip. You may need to cut the edges of this strip to get it loose but it is almost always removable. Look for the edge of this strip and try to pry it up using a flat screw driver, if it is glued into place, try to cut around the edges of the strip using a sharp craft knife.

Once this has been removed, you will also need to take the caps off each of the individual cells in order to get to the battery acid. Some batteries have small rubber caps like these, others (typically on larger batteries) have screw in plugs which can be removed with a large screwdriver, they’re not usually very tight.

Using a syringe or dropper, carefully drain each cell one by one until they are all around 50-60% full, if some cells are already lower than this then exchange some acid from the fuller cells. You don’t want to take too much out as you will then struggle to charge the battery again. The liquid you are removing is a strong acid so put it into a glass container and be careful not to mess any of it on your hands or clothing.

Make sure that you dispose of the removed battery acid in a safe and responsible manner. The removed battery acid is extremely corrosive and contains heavy metals, mainly lead.

Now you need to make a saturated solution of Epsom salts (magnesium sulphate) and distilled water. Do this by boiling water and continuously stirring in more salts until no more will dissolve in the water. Then fill each cell with the Epsom salt solution to the full level line using the syringe or dropper.

When charging the battery while it is being reconditioned, some gas will be released, so it is advisable to leave the caps open. Connect a battery charger to the terminals and let it complete the charging cycle. If the battery is heavily drained or damaged, it may have to be charged overnight with a trickle charger at a very low amperage. If you do not have a battery charger then replace the battery cell caps and covers and reinstall the battery in the vehicle. Jump start it and then take it for a full hour or two drive to allow the battery to charge using the alternator.

The reconditioned battery should now last another 6 months to a year and can usually be restored using this method about three to five times until it is no longer effective.

Edit: As some users in the Комментарии и мнения владельцев section have suggested, the best solution would be to let the reconditioning process run for a few days to properly “clean” the plates and then drain the Epsom salt solution from the battery and replace it with the recommended 35/65 acid solution. Make sure that your battery is discharged before removing the Epsom salt solution and replacing it with the acid solution.

About 15-16 months ago I added distilled water to my cars completely dead battery. I happened to have a charger that loved to overcharge, causing the batteries electrolyte to boil. I continued to overcharge and top of the fluid (in a vented area, of course). This was a test to see if it would clean hardened lead sulfate from the internal plates to extend its life. The battery lasted till this winter before drastically losing its capacity. So I’d like to safely create my own solution of battery acid mixture – just like humanity did when lead acid batteries were serviceable in the early days. I don’t see that topic covered too often.

i think you are right to over-charge the battery, this is called voltage equalisation by some people, and the extra voltage seems to be able to reduce the sulfate deposit.

I red some good methods for reconditining batteries, we can do it at home and save a lot of money. No need to throw out old batteris and i beleive these methods will helps to start a new business also. I belive this is a good guide (step-by-step guide).

Hi Otto, No you can’t use ordinary table salt. Table salt is chemically very different to Epsom salts and the process involves a chemical reaction to clean the plates within your battery which won’t work with table salt.

How do you discharge the battery ? the n you can poor out the distal water/ espson water solution? thank you

MgSO4 (epsom salt or Magnesium Sulphate) vs CaCl (table salt) H2SO4 (sulfuric acid) PbSO4 (Lead Sulphate) The idea is to use MgSO4 a highly soluble salt to pull the PbSO4 crystal off the plate.

Anonymous, If I was to empty the battery of all liquid then fill it with a distilled/baking soda mixture and let it sit for 4 hours, would the baking soda mixture pull the Lead Sulfate Crystals off of the plates? (Or does that process specifically require Epsom salts?) I would then empty the battery of the mixture and flush it with water, then with distilled water thoroughly before adding a store bought 65/35 mixture of Sulfuric Acid. Then slow charge.

No, this process is a chemical reaction which requires Epsom salts and electricity (the battery charger) to work.

The baking Soda is Alkaline, which nutralises the Acid. It will not dissolve the Sulfate. I have done a lot of reading on chemistry, and any chemical that can dissolve Sulfate will also dissolve the Lead in the battery. So, the use of baking soda in this case, is only to reduce any burning of skin, wen one empty out the battery acid.

Good post. I’m working on my military truck m929a2 batteries. I’ve bought and sold 14 of the 5 tons and each has (had) 4 of the big 6tl, dead from sitting. This truck is the first that would start under its own power, but lately no. Removing them there was very low corrosion, cells full, ranging from 10.5v to 11.5. I brought 2 inside to warm up and recondition. My charger is small, has 2 and 10 amp settings. The 2 that I’m working on are holding an open circuit at 12.35 and 12.45 so far. I understand these Exide batteries are full if they hold at 12.9. I’ll reread the procedure before I do them. Thanks.

Hey Tjoes. I know this is an old post but it caught my attention because of your mention of the military vehicles. I just got two m932A2 Tractors on a trade, so I need info on them. Specifically where can I buy parts and manuals? Got lots of air brake issues, scary when you know nothing about them. One has got 21,800 miles, the other 2,500 miles – relatively new. Any advice would be appreciated. Cheers, Wayne

I initially posted back in January. Since then, I’ve done a lot of research and have done a bit to recondition several of the batteries I have that hold a poor charge. I attempted the Magnesium Sulfate method (Epsom Salt dissolved in distilled water). This is only a temporary solution to allow electrical current to pass through the hardened lead sulfate insulator. It also helps break up the lead sulfate once it accepts the charge and is properly recharged. However, it seems as if the magnesium sulfate shortens the life of the battery afterword. I began to (using proper PPE) siphon the discharged sulfuric acid from a couple cells and noticed that the plates were breaking in to chunks. So the plates themselves are very fragile apparently. That battery was definitely no good at that point. The local automotive stores here sell battery fluid acid (30-38% sulfuric acid) in a 6 quart box sealed inside of a HDPE (plastic) bag. Generally, certain HDPE’s are storage for sulfuric acid. My next effort is to clean out a battery that has plates in good condition. Safely of course.

Hi Jack, Thank you for the great feedback. It would certainly be interesting to do some testing on a range of new and reconditioned batteries to determine the effect on the life of the battery after performing this “reconditioning”. I’ve done this process on two or three batteries now and they’ve all lasted around a year after the re-conditioning although they have all been the smaller motorbike batteries as shown in the images here. Perhaps a larger vehicle battery degrades faster. Please let us know how your cleaning out exercise goes, I’d love to include a follow up with some images on what you’ve found!

I’m not sure about the exact percentage but they are one of the most recyclable battery types. The sulphuric acid is typically neutralised and turned into sodium sulphate, which is used to make fertiliser and detergent. The lead and plastic components are then recycled into new batteries or other industrial products.

We have a vw Polo 6R. The battery died and went to test it. They said we must buy a new one. After seeing this post we’ve tried it on the old battery. And it is working like a charm. Thank you for your advise and saved us some money

Hi Pieter, Thanks for the great feedback! I’ve found that I can get at least a year or two of additional life out of my motorbike batteries using this process, it’s definitely saved me a lot of money over the years!

Hi I’m going to give it a go tomorrow but after I’ve completed the epson salt thing I’m going to put fresh acid solution back in the battery The battery will go to full charge but just doesn’t have any guts I hope I’m not disappointed Cheers stu

Hi Stu, Going to full charge but not producing any current makes a pretty good candidate for this reconditioning process. You can replace the battery acid eventually but rather leave the epsom salt mixture in the battery for a few weeks to assist with breaking down the lead sulfate crystals. As soon as you remove the epsom salts, you’re stopping the crystal removal process as well. Good luck.

Agreed ,I’ve done it Several time on 40-50 batteries. Most took 3-4 weeks if charge/discharge after which I drained and rinsed the battery and replaced the battery acid and recharged again.Some were working 10 years after production in a vehicle…

No need to add fresh acid solution to the battery. The sulfuric acid in the battery breaks into sulfur which reacts with the lead to make lead sulfide. Epsom salt is magnesium sulfide and has the same sulfur that the acid does to react with the lead. It is just as effective.

thats a very interesting concept,i live off grid so i have a relatively large battery bank plus a few older battaries from an earlier system that sat for a long time (about 3 years). i was looking for a good proceedure to reclaim these older battaries. they are deep cycle (golfcart 6 volt units) but are traditional lead acid. youre serious that epson salt can be used instead of acid in these rebuilt units?

i did the same think with the epsom salts with no luck im going to drain it out and put new acid and recharge and see how it goes

How do I safely dispose of the old acid I’ve removed from the battery? This is an excellent post with good Комментарии и мнения владельцев. Thanks all!

Hi Denise, thanks for the great feedback. Fill a bucket with water and then slowly add the acid to the water while stirring. After that add a teaspoon of baking soda at a time again while stirring until you stop getting a bubbling reaction. This should neutralize the acid and it can then be poured out in a bare patch in the garden or down the drain.

This reply is correct, but it’s important to state that you should never add water to acid (only the other way around). The reaction is very different and extremely dangerous.

The “add acid to water, not water to acid” is not about the chemical reaction (which can’t change based on direction) but about splashing during the mixing. The liquid being poured displaces the liquid in the receptacle which can splash up/out of the container and injur someone or damage surrounding surfaces. While this is still true when adding water to a battery full of acid, there is no choice of direction in this procedure and the small opening of the battery cell limits the risk.

It sure is about the chemical reaction. Water has a higher heat capacity to hold heat generated by the reaction with acid. Initial water Volume with Smaller acid Volume added doesn’t overload the the heat capacity of water. Done backwards, acid has less capacity to Dissipate heat from The reaction with added water causing extremely unstable heat from the reaction and possible explosion if too much water is added to an acid. The old chem lab motto for us was “do as you outta, add acid to watah (water)!

The chemical fact is as follows: Sulfuric acid has a great affinity to water specially when highly concentrated and it will jump out of its container towards the water when you pour the water on it causing splashes and burns, however in the case of a car battery this concentration is not high enough to cause that, having said that you should always pour acid onto water where possible.

He’s just being a safety nut cuz that’s what we learned in chemistry class and he’s theoretically right. However in The real world with a battery you could never accomplish this You have to add water to acid. Some people just like quoting safety there’s a couple guys like this at work. They have to quote everything out of a book like it’s a Bible to them.

Hello Everyone. Thanks for all your advice. Does anyone think this procedure can work with a sealed 200Ah Gel battery?

Add enough baking soda which will neutralize the acid. A lot of gas will be produced so do this in an open area. Its like taking baking soda when you have stomach acid reflux. You start burping!

Can you use the acid you took out of the battery and use it as a drain for as net to unclog drains?aren’t there commercial drain cleaners that are made with sulfuric acid?

Hi Bill, There are quite a few commercial drain cleaners which are sulfuric acid based, these would however be used by individuals who are qualified to work with it. If you do use it, use it with extreme caution. It is very corrosive and there are a number of safety risks which need to be properly managed.

I haven’t sharpened up on my battery knowledge lately but I’ll explain what I can recall. Once the mixture of h20 and sulfuric acid are injected in to the battery and an electrical charge is introduced across the terminals, the hydrogen and sulfuric acid chemically react with the batteries lead plates. The sulfate ions become negatively charged while the hydrogen ions become positively charged. What happens when the battery is losing its charge? Through chemical reaction, the sulfuric acid begins to react with the lead plates and forms in to lead sulfate (the white powdery substance you may see on a battery terminal). So if my memory serves me right, a well discharged battery would have lost its initial acidic strength. I have removed the “electrolyte” from a battery but I did not stick my fingers in there to test the level of acidity. So yes, you probably could clean out a drain with battery “electrolyte” if the sulfuric acid is present. Is it going to work as well as drain cleaner? No. The sulfuric acid content in a battery is 30-38%. Some drain “uncloggers” are advertised as 95% sulfuric acid. Lead sulfate is also hazardous. That’s something you definitely wouldn’t want to dump down your drain and introduce to the water system and environment.

Hi The DIY Life i would like to know that after i desulfate the battery should i leave the Epsom salt electrolyte inside or i mus remove it and put fresh sulphuric acid? And if so how long must i leave Epsom salt in the battery after reconditioning? Thanks Regards

Hi Tinashe, Once you’ve run through the slow/trickle charge process and your battery is fully charged again. Remove the liquid from the battery and replace it with fresh sulphuric acid for the best results. You only need to leave it in for a full trickle charge cycle.

Ok thank you i have done my battery today so tomorrow i must remove the liquid? And after taking that liquid out must i put it on charge again when i put new sulphuric acid

Yes, if your battery charger has finished charging the battery tomorrow then you can remove the liquid. You can put it on charge again after swapping out the sulphuric acid, it will probably be almost fully charged already anyway.

Last year I performed this process on a 7 year old battery that would not start my truck. The plates were smothered. The process worked and if fact the battery seemed stronger than it was when new. I worked in the industry of battery chargers for led acid batteries for 4 years. I’m very familiar with charge, float and gas stages of battery maintenance. My company developed a very special and unique stage know as pulse charging. It’s like hitting the plates with a hammer to crack and weaken the dendrite crystals formed during the sulfation phase. Even with my background I never knew you could do this! I doubted it would work. I think its just something the battery industry want’s to keep secret. I’m started the process on the same battery after the truck sat for 9 months without charging. I will let you know how it turns out. Theoretically as long as the plates and the plate doping are in decent shape there should be no limit to how many time the process can be performed.

I did two of my batteries now i didn’t come right and i don’t know where i lost it can you please send the whole process of how its done and measurements of Epsom salt with water

Hello, very interesting post. I know that, when charging a battery, a good indicator that the charge is working is the generation of small bubbles (of hydrogen if I’m not wrong). Last night I was charging my car’s battery and I noticed that one cells is not making any bubbles, is this because of hardened crystals or is it another cause? Thanks in advance.

Hi Xavier, Yes that sounds correct although there shouldn’t be excessive bubbling, just a few tiny bubbles. It could be due to crystallization or through corrosion of the cell connections or some other problem with the cell. It only really tells you that the cell isn’t charging properly, you can’t really determine why without taking the battery apart.

right. if its bubbling more than a glass of cola would its cooking. i know more about battaries than most as i have lived on them for almost 8 years (solar). but there are still things i can learn thank you for the info.

battery, reconditioning, restoration

Xavier should throw that battery out as a defective cell cannot be resolved. It is probably shorting out due to the piling up of debris from the plates on the cell floor, thereby touching the lower plate extremity. I have heard of washing out the debris and refilling to spec and recharging.

Can we use use sulpheric acid to recondition the old battery. I want to recondition sealed lead acid 6v 12v batteries. What happen if I use sulpheric acid instead of distill water and epsom salt.

Hi aakash Epsom salts must be used to create the necessary chemical enviroment for the decrystalization of the plates to be a success.

I drained my motorbike battery that did no longer held a charge. Then I filed it with 110% seawater and charged it for about an hour. It tested 12V. Instaled it in my bike and it stated after about a minute cranking. the next day it stated as if the battery was fully chaged. how long will this work with the seawater electrolite.

Hi Alternativejp, I have never heard of anyone intentionally putting seawater into a battery and I’m not sure why yours worked, chemically it doesn’t really make sense. Passing any electrical current through salt water is not the best idea as it produces chlorine gas.

Sorry, I just have to state the obvious. A few points, firstly, see water and battery cells in contact, major corrosion. If your battery had legs, it would run away. That’s a very dangerous procedure. Secondly, no need to drain and replace the epsom salt solution. It’s a very good conductor and more environmentally friendly than other toxic additives. I have been reconditioning and restoring batteries for some time and I make good money in doing so. I have restored batteries from 0 volts. No charger will accept 0 volt battery however you can use a full battery connected to the 0 volt battery with jumper cables. Leave it for a hour and then measure the voltage on the 0volt battery. It sure has more than enough volts to be charged. Thank you for a great read and some handy tips which i completely agree with. Kind regards, Johan

It works. I measured voltage of a 12 volt battery at 5 volts before unloading the old solution until the top of the plates. I then added the epsom salts solution and measured the voltage. It increased to 12 volts even without charging. Wonderful. Thanks for sharing

There is a man on the internet who swears by first filling the battery with soda and distilled water, charging, emptying and repeating until all the black runs clean. He said the charging was important to clean the plates. Then after rinsing with distilled water, he did the Epson salt with distilled. He said he has done completely dead batteries. He put it back in his riding lawnmower and it started right up. He seemed to think the soda charge was the most important cleaning step.Cayman

Question and confirmation regarding “discharge then recharge” after “reconditioning”. I have a portable photography battery pack that uses 12v lead acid batteries which have now died. The batteries are in enclosures which slide into the photo power pack for easy battery change out. I removed the battery from the enclosure and added distilled water to the cells but they will not hold the 12v recharge. Reading your post it is my understanding that I must “recondition” the cells, however, I am concerned about the gasses and discharge/recharge while in the enclosure AFTER “reconditioning”. I just want to confirm that I must now: A) Remove the liquid in the battery and neutralize with baking soda for disposal. B) Add the distilled water and Epson Salt mixture for reconditioning C) Charge the battery full D) Remove the reconditioned liquid in the battery and neutralize with baking soda for disposal E) Add ONLY distilled water and recharge Again, my concern is the use of the battery and possible gases AFTER the “reconditioning” since the caps would now be back on the battery and battery is placed back into the enclosure. Other posts seem to recondition the battery and leave the same liquid in the battery after the process. Since the battery is constantly discharging and recharging one would think that gasses would again be produced and cause possible damage. Any comment or direction is appreciated.

Your basic understanding is correct. Depending on the severity of the deposits in the cells, you may want to run them through a discharge and recharge cycle two or three times with the epsom salt solution before emptying them out and replacing the distilled water. With regards to the gases. Try keep them open and in a well ventilated place when doing the reconditioning. When you’ve put the distilled water solution back into the battery they’ll be fine again. For your application I wouldn’t suggest leaving the epsom salt solution in the batteries as it does generate a lot more gas when charging. Lead acid batteries, although sealed, do have small ventilation holes to release gases generated when charging or discharging.

Great article and Комментарии и мнения владельцев. There are some discrepancies between the many modified instructions in the Комментарии и мнения владельцев. Sometimes it’s recommended that after some time reconditioning the battery with the epsom salt solution to then remove that solution and then restore the battery “fluid” with an acid solution. Other times the recommendation is to (after reconditioning) replace the epsom salt solution with just distilled water. I’m having a hard time believing that if replacing either the acid or epsom salt solution (after reconditioning) with 100% water that the battery fluid will ever return to it’s normal acidity (35% sulfuric acid / 65% water). Should not the replacement fluid after reconditioning be the 35/65 mixture or some other ratio? Is the correct ratio dependent on other factors like the condition of the plates, etc? All Комментарии и мнения владельцев/suggestions are appreciated. Thanks.

I think the best method is to recondition the battery wit the epsom salt solution and then remove the solution after some time and replace it with the recommended (35/65) acid solution. Simply replacing the solution with distilled water will lead to very poor battery performance, as you’ve stated. In theory you can also simply leave the epsom salt solution in the battery, although performance will be slightly lower than if you replace the solution.

After reading all the posts, the last one by the OP seems to make the most sense… and is the one I will try

what i don’t understand is how the chemical reaction of converting lead sulfate. to sulfuric acid is supposed to take effect once you remove the sulfuric acid and replace it with (epsom salt) Magnesium sulfate. to my understanding the epsom salt just helps clean the stuck lead sulfate off of the lead plates and converting some of it back into sulfuric acid. it sounds to me that we will have a low concentration of sulfuric acid left in the battery. would it be better to clean the inside of the battery with epsom salt like you show, but then to drain it, and replace the sulfuric acid with new acid?

Yes you are correct John. As per some of the other Комментарии и мнения владельцев here, the best solution would be o replace the sulphuric acid afterwards.

Have tried to recondition my N70 with Epson and when I tested it was showing 12v but it can not start my car what could be the problem and how can I fix it?

Hi Luguza, did you retain some of the battery acid during the process? Did you also complete a full charging cycle with a trickle charger?

I read somewhere that short bursts of charge at 18Volts high amperage is a method used by some experts to dissolve lead sulphates… in my experience all these methods either epsom and 18v had never worked, perhaps my epsom concentration is to low, (seems to shorten the life of my batteries) and the 18V leave me only dead batteries, bikes and cars batts all died… perhaps I am doing everything wrong and all these battery methods must be extremely precise to work.

for charles i do equalizing on batteries its shouldnt be equalized no more than 16 volts otherwises ull short out the battery 5 mins on 10 mins rest repeat 5-6 times

Slight variation. I took all the acid out then washed out the battery with tap water thoroughly. Put hot mixture of Epsom and distilled water in, 1kg salts and 2L distilled water for around 20m shaking the battery a little and put onto charge for a few minutes. Then decided to poor out the salty water and put the old acid back in minus the settled out solids. Charged for 15Hrs then put into car. Cracked over pretty well.

Correct Way Of Reconditioning battery: 1. Pour out all the OEM electrolyte and save it in a plastic container 2. Dissolve 250g per Liter Epsom salt in 60°C distilled water 3. Trickle charge The battery till full. – The Mg2 ions will reduce (disolve) the Crystalline PbSO4 that is stuck on the plates (Mostly plates). Pure lead (Pb) will be deposited plate Lead Peroxide (Pb02) on the ve plates. Electrolyte specific gravity will also rise due for formation of H2SO4 acid. 4.Now that the plates are clean from the bad kind of electro chemicaly insoluble suphate (Crystalline), Time to now generate the good kind of sulphate on the plates. DISCHARGE BATTERY TO THE LOWEST IT CAN GET. 5.Drain out the epsom salt solution from the battery. Leaving it there. Interferes with the ve plates and hinders the evolution of H ions necessary for electro chemical action 6. Put back your OEM eectrolyte( Dont worry if it looks dirty).The thing is that we must restore battery chemistry to as close to OEM as possible. 7.Charge the battery with the original acid as eletrolyte. You will get maximum 85 % lost cranking power back add max 50% more life to the battery

This method works everytime! Caution though: 1. Never put Baking soda / Tap water into the battery, It Eats away the Porous (ve)PbO2 Plate 2. Never fail to Completly discharge the battery before switching over the Epsom salt solution with the old acidBattery Amperage will drastically fall. 3. If It still cant crank over a cold engine, add some acid when batt is fully charged( use a hydrometer to ensure each cell gets on the scale)

By “fully discharge the battery” do you mean drain it until a reasonable cut-off of 10.6-11.1v or even less than that? Do you risk cell reversal if you go too low?

I used MichaelM’s way and it worked PERFECTLY!! The battery would not hold a charge when I jumped started it and could drive it for 15 minutes and then try and restart it and nothing. My battery is fairly large sized and required 1500 ml of distilled water and 375 grams of magnesium sulfate. I microwaved 500 ml of distilled water in a glass pyrex measuring cup for 4 min(600 watts adjust according) and then added that hot water to a plastic cup containing 125 grams of mag sulfate. Then dumped the concentrated solution into a 5 gallon bucket. That was repeated 3x which gives 375 mag sulfate used and 1500 ml distilled water. If you dont have a digital scale, 125 grams is real close to 1/2 level cup of mag sulfate about 2 extra teaspoons. You will need a funnel and a pair of safety glasses. When charging the mag sulfate solution in the battery, it took about 6 hours at 6 amps charge. When the OEM solution was added back in to charge it only required like an hour at 6 amps. added

That is only a maximum of 36AH of capacity, assuming 100% efficiency,which is not possible,at best case scenario you get about 60% to 70% efficiency, that is a poor 24AH capacity, I don’t think this will start a car, did it work?

I forgot to add that everything was stirred until dissolved with a rubber spatula. I don’t know if heating the distilled water in a metal pan and using a metal whisk would contaminate the solution so metal items were avoided.

Interesting reading. Thank you all. I’m going to try this on some old batteries. One question though. Can one heat the distilled water to disolve the Epsom salts in, In a metal pot or use a kettle? I believe the whole reason for using distilled water is that it contains no minerals or charge. Will metal contact affect the magnesium solution? Someone microwaved the water in a pyrex beaker for perhaps that reason, which makes sense to me.

I have a riding lawnmower size battery out of my motorcycle. It was purchased new 2 years ago, used only a month and then placed on trickle charger for a year while i restored the old bike. now it is too weak to start the motorcycle, doesn’t take a full charge well. So…. I have drained the acid and replaced it with epsom salt solution and as of this writing it is on a 12 volt 2 amp charger. my charger is 12v 2A/6A model. Q: Should i be charging at higher rate of 6A? Q: Do i drain epsom solution after 24 hours and replace with acid?

You should charge it at the lowest current possible, so 2A. Try leave the Epsom salt solution in for a week or so and then drain it and replace it with the regular acid solution.

Was the battery left in freezing temps? If so, it’s not worth the effort. The plates become brittle and crumble apart. At least with the batteries I’ve attempted to revive.

I am refinishing an aluminum boat and it has 3 group 27 deep cycle and 2 group 24 standard starting batteries installed. They were fully charged when it was dismantled for painting 3 years ago. I was expecting to replace all batteries but I was getting excited reading all of the posts about the recovery process. Thanks for adding the comment concerning recovering frozen batteries not being worth the effort. Do you know what the difference is between the deep cycle battery and a normal one? Can you check the resistance of the battery with a multi meter to see if it is a good good candidate to recover? Thanks for al the info.

Hi Dave, Great to hear you’ve been looking into reconditioning your batteries. Briefly, deep cycle batteries generally have fewer and thicker plates than normal vehicle batteries. They have a higher reserve capacity but produce a lower maximum current than a normal battery. Battery health is quite a complicated science and there are a number of attributes which affect it, internal resistance being just one of them. This being said, I don’t think that you’d get any really meaningful information for recovery out of measuring their internal resistance unless you had some historic test data for a number of the same brand and model batteries. It’s not an expensive process, so I’d give it a try on one or two batteries and see what results you get. You may be able to save yourself a significant amount of money. And if you can’t, then you’ve just wasted a box of Epsom salts. I would only proceed with replacing the electrolyte solution if you got reasonably good results from the Epsom salt solution.

I do not know much about chemistry but what happens to the magnesium in the Epsom salts. I assume the sulfur in the Epsom salts helps replenish the acid but I wonder what effect the magnesium has in the solution. Would it be better to replace the solution with fresh electrolyte after it has done its job of cleaning the plates.

Yes, you’ll need fresh solution for each. I’d do them all at once and mix up a bigger batch of solution.

The directions in the original post say to take the battery out of the vehicle. Is that really necessary? and if so, why? Thanks for a great post and for all the interesting and helpful Комментарии и мнения владельцев.

There is a way to do this method and still get the battery back to 89 to 99 % life I have one I did that lasted 13 years after doing this and using a desulfnator inline while charging it.also I dumped all the acid put it in an old washer fluid bottle I cleaned out let the sediment settle and pulled off clean acid from the top added it back to the battery added the Epsom solution and charged the battery at 10 amps for 1 hour then changed it to 2 amp for 7 hours drained the fluid and hosed the battery out makin sure it was clean water coming out when I was done added new acid back and charged it on auto charge with a top line charger ….the charger also makes the difference you can not use a new charger or one with auto charge when you run the first phase…I been doing this since I was a kid was taught how to do it by my grand dad who was a mack truck mechanic …

Hi Grey Wolf, Thanks for sharing this with us. It’s great to hear that these restoration methods have been used for a few generations already!

Hi thanks for such an informative website. I am stuck up at home in lockdown since 4 months. my scooter battery Amco 12V. VRLA type lead acid battery didn’t charge up. scooter was not driven due to lock down for long time and then left in rains, first I suspected wiring short but later on checking the charging wire by kicking the scooter found that battery is at fault. connected a dc.dc 5V to 15V adjustable voltage booster for charging battery but the charging current is just 20 mili Amp. and the voltage dont sustain even while checking it rapidly drops down. Googled a lot and came across your website, so decided to desulphate! I committed a mistake I didnt drain the battery of the initial battery water or acid in it. the design of the VRLA battery is some what makes us get a false impression that the water level is between the min and max levels marked in the outside. I checked by a flashlight from the side walls and saw the light coming out from the other end when I shook the battery the liquid inside was well within the marked levels. when I opened the battery. I was surprised to see that in each of the 6 cells the water level is very low, very shallow and I have been trying to charge it with my voltage booster since 3 days. Since the water itself is very low I didnt drain it. I added around 15 to 20 gm of powdered epsom salt in a cup of boiling water about 100 ml and injected it with syringe in each of the 6 cells. as I kept on pouring there was Rapid effervescence and bubling with gas formation. which gas ? it was horrible something like chlorine or sulphuric acid itself. seemed as if the acid is boiling! then i realised it was a bad idea. but somehow i thought to finish the process it was becoming difficult to breathe, I wore wet face masks and avoided to inhale as much as possible. later left it in a open area on the roof of my house. the droplets of water epsom solution at the mouth of each cell started turning green my question what gas was it possibly sulphuric acid itself? is the battery still safe and shall I charge it to see if it can hold charge now? or will it blast off or something ? shall I take it to a professional garage? I have a garage who works from the backdoor somehow during lockdown, he shown me his charging set up a huge transformer power supply at 16.5 Volt ! will it be safe to charge this battery at 16.5 V or shall I try charging at lower value ? shall I drain the battery solution now ? or use it for a few days and later drain it or leave it in this state? pls help

Hi Navin, I haven’t had much experience with VRLA batteries, hopefully someone else here has. I do know that its normal for their level to be very low, they’re intentionally made this way. Is the battery an AGM or Gel Type? I would imagine that either way this restoration method is going to be inhibited in these battery types because their design intentionally limits the movement of the electrolyte, which is going to prevent your Epsom salts from mixing into the solution properly. Also, 16.5V is too high to charge a lead-acid battery safely, they should be charged at around 14V.

I have tried to charge my BMW X5 battery as per the following method a.I made a solution of baking soda ie 500 g baking sode to 5 l of wate a. I repeated the wash out process with baking soda twice. b.I then made a solution of 500 g of Epsom salt to 5 l of Distell water. c. Charged the battery for 6 hours. d. Put it back in the vehicle and tried to start……did not start e. The battery was charged to 12.4v ?? What am I doing wrong ? Sunny South Africa

Hi Indran, You need to retain some of the electrolyte solution during the reconditioning process. The liquid in a battery is an electrolyte which is diluted with distilled water, removing it and replacing it with just distilled water will result in a dead battery. You need to remove the water and add a 35/65 acid solution and then try the process again.

I had someone attempt to recondition my lead/acid golf car batteries. They said that they had reconditioned many batteries in the past. The batteries were about 6 years old. Long story short: It didn’t work. The golf car moved at about 5 mph for a block and then died. I am now shopping for sealed glass mat batteries. I don’t want to fool with the open batteries anymore. Glass mat batteries are expected to last 8 years in a golf car with a lot of use. I don’t golf but I find the unit nice for one to two mile runs around town several times a week. Our town has golf cart lanes on every street because it is considered a retirement community.

This is a most intriguing conversation and it has me wondering. In running an off grid power system, there is a bank of deep cycle lead acid batteries in a utility shed, that each require replacement every 5 years roughly. An expensive and labor intensive headache, that could be greatly reduced if there were a way to refurbish the batteries. Furthermore, if the acid and decrystallize solution can be stored onsite and pumped directly into the batteries… Couldn’t an automated system be setup to perform this de-crystalization and replacment of acid?

I guess in theory this may be possible. The problem is that each battery has six cells, which you need to individually drain to a certain level and then refill. So you’d need quite a complex dosing system to split off into 6 individually controlled drains and dosers for each battery as well as a way to measure the electrolyte level in each cell.

Thanks for this very helpful information. I have a car sitting there for over a month and I had to jump start that car. After some driving, i thought the battery was charged but I couldn’t start the car. After second jump start I drove for an hour and still won’t start next time. I bought a 4amp auto charger and changed 2 days and never reach full charge. I bought a different 1 amp charger and charged more than 3 days, still unable to complete the charge. I opened the 6 cell screws and noticed all cells except one have small bubbles when charging. Does this mean this cell is dead? Can I still follow this procedure to repair this battery? if so, since all cells are individually screwed, can I just do these steps on the one cell that doesn’t make any bubbles?

My solar battery reads 13V when I test it but it is not pushing any current. What could be the cause? Can I just add distilled water and recharge it?

battery, reconditioning, restoration

If you put a load on the battery does the voltage drop significantly? It seems like your battery is dead, you should try reconditioning it as per the instructions here.

Hi ,we are working about repair and revive seald battery, especially UPS battery, my question is, can we change the plates of battery ,means when we cannot achieve good results from charging and chemical Procedure we open the door of battery and change defective plate ,thank you

I doubt you’d be able to source replacement plates and they’re generally sealed into the battery when it’s made up.

Yes, battery plates replacement is a common procedure in 3rd world countries like Pakistan. You can look for a battery repair shop near general bus stand of your city.

You buy a car and use its original battery for 2 years. Replace with a 2nd battery and trickle recharge the 1st for the next 2 years. Then swap them again and trickle recharge the 2nd battery for 2 years. Then swap them again and trickle recharge the 1st battery for 2 years. And so on and so forth. I used a 4 amp charger that automatically adjusted the charge rate down as the battery charged., used intermittently 3 months at a time. The longest use I obtained from a battery was a 1972 Dodge Dart Swinger with 225 cu in inline “slant” six. Its original equipment battery lasted for 6 years and the “alternated” replacement battery lasted for 8 years and was still in the car when resold. It continued for another 2 years according to the 2nd owner, Trickle maintenance charging works. Never added MgSO4 Epsom salt, never dumped acid or added acid. Never even checked the voltage. I just used distilled water without any additives (watch out, some have additives!) I kept the battery in the basement where the temp was between 50F to 65F year round. So, 14 years for two batteries (actually 16 years) with no failures to start in New England’s sometimes below 0 temperatures. And, I only bought one battery in 14 years. IMO, a 2 amp charger is all you ever need. Long slow charging done frequently out of the car works better than charging in the car, but charging in the car is better than not charging at all. It doesn’t help with lead sulphate unless you disconnect the negative pole. Microprocessors in modern cars leak current continually for anti-theft and some leak current through accessories unless you a certain to TURN THEM OFF before you shut off the car’s engine.

It seems to me that there are a lot of people out there that have a problem reading and following instructions.

Yes. It’s because of the “no child left behind” experiment brought to us by the “everyone gets a Trophy, even the Losers” section of society.

Why not replace the MgSO4 solution with fresh electrolyte after the cleaning process? Any experience here doing this?

You can replace the solution with fresh electrolyte after cleaning, a couple of people in the Комментарии и мнения владельцев have done so and reported good results.

I have always use baking soda and regular water to remove the crystals from the battery. Then I use epsom salt and distilled water as the battery acid solution. That solution remains in the battery and I don’t replace it with sulfuric acid. It seems to work fine.

Seems to me if you add the water with the Epsom salt as soon as it’s done boiling in all crystals have dissolved to the battery it charges faster and gains acidity faster just saying!

If your battery was discharged over a few days (still applies up to a few weeks) to 0V, here is some info that may help IF you have the capability to current limit your voltage supply, i.e. current limited voltage supply. Note: My car battery charger wouldn’t charge the battery because it couldn’t detect a voltage (it was 0 V) and I knew better to try and jump start it with another vehicle because it could damage the alternator. Another note: If your battery charger doesn’t work because the battery is at 0 V and you don’t have a current limited supply but you do have a voltage source of 15 V or less you can prime your battery to a non 0 V state, now you can plug it in to your battery charger. Pre-check: Pull your caps off of your battery (use proper PPE) and make sure all of the cells are fully covered with liquid. If not, add distilled water only being sure not to over fill. 1. Set your current limit to 1 A. You can use up to 1.8 A if you wish, batteries are just more forgiving when at lower currents, this is my preference only. 2. Set your voltage to 13.5 V. 3. Turn the supply on, your current should be limited based on your setting and you will slowly start to see the voltage increase. This may take 7-10 hours or more based on your current limit. See this link if interested: 4. When 13.5V is reached the current start to drop off until it reaches a lower steady state. Your battery is fully charged. 5. Reverse the soft sulfation. Set your voltage supply to 15V with a current limit of 0.2 A (200 mA). 6. Turn your supply on for 24 hours. See this link, paragraph 6, if interested: 7. Turn off supply, re-install battery.

I’m not sure if I’m right about this but I do believe when you apply a current to a absent salt solution The Epsom salt is converted to sulphuric acid. Is in the process of that happening the Epsom salt takes electrons from the sulfides on the plates. That releases the salt fides from the plates and restores the battery. If I’m not positive if that’s how it works if I am wrong I would appreciate if somebody could correct me that would help me out on several levels.

I have done this with baking soda to clean out and used regular tap water. Filled the battery shook and dumped until no more black suet came out. Then let drain upside down. Added 16 oz of epsom salt to a 2 quart bottle of distilled water and dumped into battery. No need to boil cause as you charge it will boil anyways. Charge for 24 hours maybe 48 if needed. Hookup battery to car leave head lights on and let the battery drain till the lights start to dim. Then recharge the battery for another 24 hours. Then good as new. Seems like a lot of work but this way will yield best results.

HELP! I got a 12v marine deep cycle type 24 battery for free. Owner said it was dead. I drained all the fluid that was left in it (not much) and then filled the cells with a distilled water/ epson salt solution until I could just see some solution. (I put as much epson salt into the boiling distilled water until it wouldn’t disolve anymore). I left it like that for about 5 hrs or so. (no charging). I checked it with my multi-meter and it reads 34.2 volts! I thought my multi-meter is going bad so I checked 3 other deep cycle batteries I have that are topped off and they all read 13.1 volts. I then checked the type 24 again and again it reads 34.2 volts! How can this be?

Question?: do we need sulphuric acid(if so how much?) or simply drain the epsom salt and just pour in distilled water.thank you

Yes, you need either the sulphuric acid (can’t tell you how much) or the epsom salt mixture can be left in the battery instead. Water will not work. I use the cheap Leroy-Merlin swimming-pool acidifier 35% sulphuric acid.

Hello. I have an industrial forklift battery that is “dead”. I could use some guidance in rejevenating it. May you help?

Battery Reconditioning​

Kevin Miller width=100 height=100 /

Last Updated on July 8, 2021

H ello guys! Thanks for visiting our place. Today we are going to share with you some of our ideas on battery reconditioning. Most people think reconditioning old and dead batteries is highly technical and complicated.

Well, it is not that difficult to follow, and the battery reconditioning method we’re going to share is practical and straightforward. There are several types of cells that we can recondition, but today we are going to show you how to recondition any dead batteries at home.

There are a few benefits that we can enjoy when we recondition a dead battery. One, we can save a few bucks from buying a new one. Second, we can help mother nature by reducing its pollutants.

Just read through the whole article to know more so that you’d know how to recondition batteries at home. Let’s get started…

What is Battery Reconditioning

Battery reconditioning means bringing back the healthy life of a battery, that is, full charging capacity and standard electrolyte level. This is important because whether you have a regular car or a luxury type, low charge, and acid stratification are the typical concerns among owners.

Every time a battery discharges, lead sulfate crystals are formed around its plates. The massive buildup of these crystals affects the charging and discharging capacity of your battery.

Some of the batteries which can be reconditioned include AGM, 12v car battery, gel batteries, golf cart battery, lithium-ion batteries, prius battery, NiCad, and NiMH rechargeable batteries.

Having practical knowledge of reconditioning batteries is excellent so that you’d be able to keep your battery at optimal performance.

Who Benefits From Reconditioning Dead Batteries

Knowing how do you recondition a dead battery is practically beneficial to the owner and the environment.

For the car owner, gaining that knowledge and skill would save you a few bucks and the hassle it brings when the battery dies, and you are in the middle of nowhere.

Aside from that, for those who want to have a few incomes. You can practically charge a few bucks from people who wish to their battery reconditioned. Perhaps, you can recondition some of your old and dead cells in the garage and resell it for a reasonable price.

over, the environment also benefits from battery reconditioning as a lesser amount of lead-acid solution is disposed of in the surrounding. These chemicals, when not cured before disposal, can pollute the soil and groundwater, which causes several health consequences.

Safety Tips for Battery Reconditioning

When reconditioning batteries, safety measures must be kept in mind to avoid accidents along the way. Be reminded that the electrolyte inside a lead acid battery is corrosive and harmful when in contact with skin, eyes, and garments.

These are some of our tips you can follow to maintain safety during battery reconditioning:

  • Wear rubber gloves to protect your hands from the acidic electrolyte solution
  • Wear goggles to protect your eyes from any splattering
  • Wear an apron to protect your clothes from the corrosive liquid
  • You can prepare a weak basic solution made from baking soda and water to neutralize any spills of the acidic electrolyte solution.
  • Work in a well-ventilated area so that the harmful fumes and heat from the electrolyte solution will be readily dissipated — likewise, a lesser chance for you to inhale much of the vapor. You can also use a disposable mask to filter the air you breathe while doing the whole process.

We highly emphasize prevention over cure. Be careful in preparing and transferring electrolyte solutions to your battery.

How to Recondition Batteries

Are you still there? Now, we are here for the meat of the article on how to recondition old batteries. Just read through the whole process, and in no time you would grasp the entire concept.

Materials Needed

So, here are the necessary things you will need for the entire procedure.

  • Funnel
  • Distilled water
  • Baking soda
  • Epsom salt
  • Voltmeter
  • Screwdriver (flat head)
  • Goggles
  • Disposable rubber gloves
  • Apron
  • Bucket
  • Battery Reconditioning Charger

STEP 1 Prepping the Battery

Before you prepare your battery, make sure you are wearing your safety gear: goggles, rubber gloves, and apron. Likewise, ensure you are working in a well-ventilated area which is also near to a water source in case you would have spills or splashes on your skin or clothes.

In preparing your battery for reconditioning, make sure its terminals are clean and free from corrosion or any salt buildup. The battery must be removed or detached during the whole reconditioning process.

You can prepare a DIY baking soda solution for cleaning some corrosion in the battery terminals. The ratio for baking soda and water can be either 1:1 or 2:1. The corrosion or salt buildup in the terminals is slightly acidic, and so this basic cleaning solution can help in the removal and neutralization.

Mix baking soda and water in a container until you reach a gritty or paste-like textured solution. After, take a clean or used toothbrush and dip it in the solution and then rub it on the battery terminals.

Meanwhile, for heavy corrosion on the terminals, we recommend the use of a steel brush, steel wool, or a fine sandpaper grit. The extra abrasive texture will provide better scraping performance in removing corrosion.

STEP 2 Check Voltage Level of Your Battery

After the prepping, you need to check the voltage level of your battery if it is in good condition or not. It would be best if you had a reliable voltmeter in doing this one which can be readily bought in electronic shops.

The voltmeter has two wires with one metal clip at both ends for each cable. One wire is color black for the negative terminal, and the other wire is red in color for the positive terminal.

Connect the clip of the red wire to the positive terminal of the battery and the black coil to the negative terminal. If it’s a car battery an indicator to know if your battery is already in good condition and fully charged is the reading must be 12.6 volts and above. When the battery is inside the car, and the engine starts, the reading must be between 13.7V to 14.7V.

If the voltmeter reading is below 12.4V, then your battery needs reconditioning. Write down the details of your voltage reading for reference.

STEP 3 Remove the Old Electrolyte Solution and Wash Battery Plates

Before doing this, you need to have your bucket ready for receiving the old electrolyte solution and some weak baking soda solution to neutralize some spills while emptying the battery.

Take your flat head screwdriver and remove the battery caps. After, secure your battery caps in one container and slowly lift the battery and pour out the old electrolyte solution into the bucket. For any spills, pour a substantial amount of the baking soda solution on the affected area to neutralize it.

To neutralize the battery acid solution inside the bucket, you can add 1/2 pound of baking soda powder into the bucket. Another option is to make a 3:1 baking soda and water solution to pour into the bucket for neutralization of the acid. Once neutralized, do not dispose of this yet.

For cleaning the battery plates inside, prepare a baking soda and water solution with a ratio of 1:1 or 2:1. After making the baking soda solution, fill each battery cell to the full level, and close it back with the battery caps. Lift the battery and do some shaking for like 30 seconds to 1 minute, then you can let it sit for another 1 minute to allow some reactions to happen. After, open the caps, empty the battery and pour the baking soda solution into the same bucket.

Check the bucket for a neutral pH level between 6.8 to 7.2 before disposal. You can contact Earth911 for further details on the proper disposal of battery acid solution.

STEP 4 Bring it Back To Life: Reconditioning Batteries

The next step is to replenish the electrolyte solution in your battery. For this, you can use Epsom salt and distilled water to create a new battery solution.

The concentration of Epsom salt solution must be around 1molar. This is created by dissolving 120 grams salt in 1 liter of distilled water. You can slightly warm the water to ensure all salts are dissolved.

After preparing the salt solution, fill each battery cell to the full level and return, and cover the cap. Once all battery cells are filled, your battery is now ready for recharging.

STEP 5 Charge the Refilled Battery

Grab your battery charger and connect the red wire to the positive terminal of the battery and the black to its negative terminal. Place the charging condition in slow mode 2 Amps for 12V and let it sit for 24 to 36 hours.

Detach the charger from the battery after 24 to 36 hours. Then measure the voltage of the battery. If it measures 12.4V to 12.6V, then your battery is in excellent condition already.

STEP 6 Subject it to Load Testing

You can do this using a battery load tester which you can buy in any hardware shops. To pass the load test, the reconditioned battery must sustain 9.6V for 15 seconds tested at half the CCA rating.

CCA rating refers to the Cold Cranking Amps delivered by a 12V car battery at zero degrees Fahrenheit and a minimum of 7.2V for 30 seconds. The higher the CCA rating of the battery, the better its performance.

Your battery must have a higher CCA rating as it degrades through time and to cope during cold seasons. It is easier for your engine to start in warmer temperatures but to have a higher CCA rating gives it more advantage during low-temperature conditions.

If your reconditioned battery failed the first load test, you need to discharge it and recharge it back. Then do the load test again to check its CCA rating.

Frequently Asked Questions

Now, we are done sharing our thoughts on how to recondition old batteries. However, there are other things we were not yet able to cover for this article. Nevertheless, we have some FAQs below where you can find some of your unanswered questions.

How long is the lifespan of a reconditioned battery? The lifespan much depends on what type of battery you were reconditioning. On average, reconditioned batteries can have a lifespan of 1 year.

What are your estimated savings from battery reconditioning? When you buy a new battery, the cost can range between 75 to 100. Meanwhile, if you know how to recondition dead batteries, you can save around 25 to 50 percent of the retail cost.

Can you pour vinegar into your battery to refill the lost electrolytes? Never add vinegar to the electrolyte solution inside your battery as the sulfuric acid and acetic acid will react and form lead acetate in the terminals. Instead, add a little distilled water to fill up the lost electrolytes.

How long can a battery sit without being used? On average, an unused battery can stay in good condition for about three to four years. However, this condition will also speed up battery degradation, particularly when exposed to extremely warm or cold conditions.

When is it not advisable to recondition your batteries? There are three factors that can tell you if it is not good to recondition your batteries.

  • If you have already reconditioned your battery three times, for each reconditioning, you do not fully restore the whole performance of the battery. Likewise, it degrades in every reconditioning process, so you do not expect the same condition as the brand new ones.
  • If the battery incurs excellent damage, then it is no longer suitable for reconditioning as it may worsen.
  • If you do not have the right materials, then do not push through in reconditioning batteries at home. This might put you and your battery in a risky situation.

Are there other methods of battery reconditioning? Yes, there are other methods you can apply for reconditioning batteries. The way you can use will also depend on the type and size of battery you have.

Likewise, some batteries have a “memory effect” on their capacity. Frequently, this happens when you overcharge or immediately charge a battery even if it is not yet below the stated level, opt for charging.

How to Recondition a Car Battery?

Most cars still use lead-acid batteries of some kind. wet/flooded, AGM or even Gel-cells, but these batteries over time lose their capacity and the ability to start the engine.

battery, reconditioning, restoration

Since quality car batteries are not cheap, many people wonder how they can recondition a car battery at home. Reconditioning car batteries at home can be done successfully, but this also depends on the battery type, its use, age, current condition and similar.

Lead-Acid Batteries 101

For short, lead acid batteries consists of positive and negative lead plates and diluted sulfuric acid as electrolyte.

Lead plates are sometimes made of pure lead, sometimes with added calcium and other alloying elements in order to achieve certain goals, like stiffer plates, lower self-discharge rate, etc.

Chemistry: Charging and discharging process is reversible and includes creation of Pb and PbO2 (charging) and PbSO4 (discharging) on the battery plates (very simplified). in the fully charged battery, the negative plate consists of Pb (lead), and the positive plate is PbO2 (lead dioxide).

However, charging/discharging cycles are not perfect. with each cycle, newly created Pb, PbO4 and PbSO4 are not formed in the ‘exact’ proper way as before.

Also, lead–acid batteries lose the ability to accept a charge when discharged for too long due to crystallization of PbSO4 (also known as sulfation process).

There are other processes that over time, little by little decrease the battery’s capacity and its ability to provide large currents.

Types: Most common lead acid battery types are wet/flooded, AGM (Absorbent Glass Mat) and Gel-Cell batteries.

Wet/flooded batteries have their electrolyte in liquid form, hence the name. Over time, water from the battery is lost and must be added in the form of distilled water. never add a tap water into the wet/flooded battery.

AGM and Gel-Cell batteries are Sealed Lead Acid (SLA) batteries and there is nothing what common user can do regarding the electrolyte. there is no need (and no option to do so) to add water during the operating life of the battery.

Reconditioning Car Batteries at Home. Recommended or Not?

Well, there are several ways to recondition a car battery at home.

One of the ‘most famous’ methods which is applicable ONLY to wet/flooded batteries include removing sulfuric acid from the battery, cleaning the cells with baking soda and then adding custom electrolyte based on the Epsom salt (magnesium sulfate) and distilled water.

To do this at home, one requires open area (it should not be done inside, no matter ‘how well’ the area is ventilated. ), protective gear (gloves, goggles, etc), chemicals etc.

But, personally, it is not recommended for many reasons:

For short: not recommended, to say the least!

However, there is a much simpler and much safer method of reconditioning a car batteries at home, regardless of the type (wet/flooded, AGM, Gel-Cell) and charge/discharge level (even if the battery is fully discharged, down to the cell reversal) etc get a Smart lead-acid car battery charger. It is that simple.

Features and Specifications of Smart Lead-Acid Battery Chargers

Smart lead-acid battery chargers are microprocessor controlled devices that analyze the battery condition and charge it according to:

Note: Never, but really never charge lithium batteries with charges not designed for such batteries.

If you have wet/flooded battery, be sure to check electrolyte level prior charging and if required, add some distilled water. Also, check maximum allowed charging current of your battery and be sure to use battery charger that features maximum charging current lower than the battery’s maximum allowed charging current. charging the battery with too strong currents may destroy it easily, especially AGM and Gel-cell batteries.

When charging process starts, Smart battery chargers analyze the battery and start with the recovery/charging (depending on the settings/model of the Smart battery charger):

Note: some battery chargers even feature ‘Force Mode’ allowing the user to override microprocessor and to ‘force’ the charge into the (almost) dead battery. This is not recommended charging mode, but if the battery is (almost) dead, this mode can bring it back to life.

Connecting the fully charged battery to the battery maintainer or to Smart battery charger is recommended method for wintering the lead acid batteries, although with newer batteries with 3% or less monthly self-discharge rate there is no need for maintainers at low temperatures for months.

Smart battery chargers also come with many safety features like overcharge/over-voltage protection, reverse connection protection, short circuit protection etc.

But, no matter how safe modern Smart battery chargers are, be sure to read their instructions/manuals and to act accordingly. Stay safe!

Long Story Short: If you want to recondition/rejuvenate your car battery and prolong its operating life, get a good, thoroughly tested in real life conditions Smart battery charger, take the battery out of your car (if allowed by the car’s manufacturer due to many onboard electronic systems powered by the main battery even when the engine is turned off), place it on flat, firm surface in well ventilated area, set the battery charger, connect it and let it do its job.

Again: reconditioning a car battery using baking soda, Epsom salt and similar chemicals. big no, no. Be Smart and stay safe!

If you are stumbling around to know, how to bring a deep cycle battery back to life, you are at the right place. I will explain to you in detail, how you can repair an old battery so that you can use it for some more couple of years instead of buying a new one.

Deep cycle batteries are specially designed lead-acid batteries, known for maintenance-free and longer life span. A normal car lead-acid battery gives a quick burst of current for ignition or other purposes. In contrast, deep cycle batteries are capable to provide steady current for a longer duration. Hence, deep cycle batteries are preferred in off-grid or hybrid solar power systems.

If a battery is left unused for a longer duration, it produces sulphate crystals on the plates of battery cells. The sulphate crystal minimizes acid contact with the cell plates, resulting in Rapid charging and short discharging time. This makes the battery ineffective or sometimes useless.

Going straight away to buy a new battery is not a good option all the time. It will need an investment in new battery which is an expensive solution. In many conditions, you can recover the battery or enhance battery life for some more years.

In a battery, there may be a sign of not holding a charge, or even not taking a charge, you can try to repair it to get more out of it. A series of steps are given here which you can follow to get your battery back to life.

battery, reconditioning, restoration

Before starting off with the repairing procedure, you must take these points in mind,

  • Strictly follow the precautionary measures where discussed in the procedure.
  • Use proper or appropriate tools for every job done with the battery.
  • Battery inspection is very important procedure, do not overlook it in any case.
  • While caps of the battery cells are open, try to avoid contact with electrolyte (water) inside the battery as it is acidic in nature.
  • While charging the battery for the first time, pay attention to it regularly for first couple of hours. If body of the battery is too hot to touch, disconnect the charger immediately.

These tools will be used in repairing process while performing different steps.

  • Battery charger
  • Battery Desulfator
  • Battery Load Tester
  • Flathead or Phillips head screwdriver
  • Dry rag or a piece of cloth for cleaning
  • Baking soda
  • Distilled Water
  • Wrench or spanner for battery clamps

You will need to thoroughly inspect the condition of the battery. Check for any leakage in the battery because water level may go down due to leakage. Remove the battery terminals if they are connected. You should have two wrenches or spanners of correct size to loosen the battery clamps. In some designs of the battery clamps, you may need to use a flat head or Philips head screwdriver to remove the clamps.

Battery terminals get corroded as the battery ages or due to environmental conditions. A white or greenish-blue powder forms at the terminals. You should use gloves and safety goggles while doing the cleaning as the powder is toxic. First, clean the battery using a dry rag or any piece of cloth. Add 3-4 tablespoons of baking soda in a glass of water. Then, use the solution to clean the battery surface with a piece of cloth.

Inspect for the battery cell condition

Open the cover or caps from the cells of the battery and check for the water level in each cell. If there is no or little water, then inspect for the condition of the cells as well. They should be at least moist, otherwise, there are chances of the battery destroyed. Look into each cell for the accumulated debris at the bottom. When the battery is dried off too much, the stuff from the plates is shed off and accumulated at the bottom. This stuff shorts the bottom of the cell plates and charging this battery is dangerous.

Pour water in each cell of the battery

Now, the time is to add distilled water in the battery. If the condition of cells is good, pour distilled water in the cells up to the given mark. If there is no mark given, try not to overfill the battery and leave some space at the top. Do not use tap water or water from any other source, no matter how clean it is. The reason is that tap water has different salts dissolved in it depending on the source of water. These salts enhance the process of corrosion in the cells.

Put the Battery to Charging

For first charging after the above treatment, use a slow charger of 1-2 Ampere to avoid any damage to the battery. If you do not have a slow charger, you can use a regular charger with precautions. Some intelligent chargers have a safety feature not to charge a deep-discharged battery as they consider a battery below 10.5 V as defective.

Use a good battery in parallel if needed

To deal with such intelligent chargers, you will need a good battery with voltages above 12 V and battery jumpers. Using jumper cables, connect the repaired battery in parallel with the good one i.e. positive with positive and negative with the negative terminal. Now, connect the batteries to the charger. The charger will sense the voltage of the good battery and will start the charging process.

Keep an eye on the battery while charging

Let the battery charging continue for about an hour. During that time, keep an eye on the battery if you hear any kind of hissing sound (gassing) from the battery. DISCONNECT IMMEDIATELY if you hear any hissing sound. After an hour, check whether it is slightly warm or hot to touch. If you feel that the body of the battery is hard to touch or hot, DISCONNECT THE CHARGER IMMEDIATELY. If it is slightly warm, then let the charging process continue. Batteries become a bit warm while charging.

Remove the good battery if voltage improved

If you applied the method of paralleling the good battery with the repaired one, remove the second battery (the good one) after 3 to 4 hours if your main battery’s voltages go above 12 V. To check the voltage, disconnect both batteries from the charger and disconnect them from each other as well. Now, using a voltmeter, measure the voltage on the repaired battery. If voltages are above 12 V, reconnect only the repaired battery to the charger. Let the battery charge for 24 hours. After that, disconnect the battery from the battery charger and measure its voltage again if they are satisfactory or not.

Use Battery Desulfator to Remove Sulphate Crystals

While performing the above charging procedure, if you find that the charging process is very slow or no charging at all, you will need a battery desulfator. Alternative names of battery desulfator are battery resuscitator, battery rejuvenator, or battery reconditioner. As it is explained earlier, if the battery is dried up too much or deep-discharged, sulphate crystals are formed on the surface of the plates of battery cells. We need to remove this sulphate from the battery cell’s plates.

A battery desulfator is a device that enhances the capacity of an old lead-acid battery and extends the life of the battery. It provides pulses of high voltages or high frequency (depending on the technology used in the device) to the battery causing a current flow that reverses the crystallization process of lead sulphate. The desulfation process takes one day to three weeks depending upon the duration of the battery remain unused or damage caused to the battery due to the deep discharging.

Perform Charge and Recharge Cycle

It is a practice of experienced people to do the desulfation or charging/discharging repeatedly. Let me explain it to you. If you are doing the desulfation process, keep the battery on desulfator for two days, give it a rest for one day, and repeat the process. Measure the voltage at the end of each cycle and note if there is an improvement in the voltage. Repeat the desulfation process until you see no further improvement in battery voltage. Remember that disconnect the battery from the battery charger before measuring the voltage to get an accurate reading. In the same way, if you are charging the battery, charge it completely up to the limit possible and discharge with a load. This charging and discharging process help the battery to recover.

In battery load testing, current produced by a charged battery is measured. We use this method to measure the health of a battery. First, you need to charge the battery until you get output voltage equal to the labelled voltage indicated on the battery. The voltmeter reading should be in the range of 10 percent of the labelled voltage. Connect the battery to the load tester and press the button to test the battery health. If the needle remains in the healthy (green) zone, the battery is in good condition.

If you do not have a load tester, you can connect the battery to a random load like 12 V street light or headlamp of a car. The brightness of the light should not go down too early.

Conclusion. How to Bring a Deep Cycle Battery Back to Life

The recovery chances of a battery are 60 to 80 percent. The recovered battery can give an extended life of 6 months to 2 years depending on the amount of sulphation or damage to the battery due to overcharging, deep-discharging or battery heat up. A deep cycle battery does not need regular watering, a regular inspection is still recommended. It is recommended to use modern and efficient chargers, charge controllers or solar inverters which have options to care about the health of the battery.

It is one of the expected costs for many units after two years of usage.

Best Deep Cycle Batteries

Whether you are looking to install a solar panel in your home to go off-grid or stepping up your fishing game by getting yourself a boat, sooner rather than later, you are going to require a deep cycle battery. And unlike car batteries, many people have no understanding of deep cell batteries because they are not needed that often so if you are also one of those many people who have zero confidence while choosing a deep cycle battery for themselves. There is no need to fret. I have cherry-picked 5 best deep cycle batteries with help from my prior experiences and reviewed them in detail. You can read through each of the battery’s reviews and figure out the one that will be the most ideal for you. How To Pick The Best Deep Cycle Batteries For Your Needs Before you dive deeper into the batteries’ descriptive reviews, it is essential to know what features and attributes you should keep in mind when searching for a deep cycle battery in the first place. I have also inserted some questions here that people often ask while purchasing a deep cycle battery. You can check them out too. What to look for when choosing the best deep cycle batteries? When buying a deep cycle battery, check the battery’s capacity and always inspect whether its battery capacity will be enough to run whatever you want it to run smoothly or not. Also, see that if you are going to harness small output from the battery, there is no need to buy a large capacity battery. The high capacity batteries cost more, plus the extra energy would be of no use to you. What brand should you go for when buying a deep cycle battery? Some people skip this part because, to them, a low price is an utmost priority. But, I would never advise you to go for a shity two-star brand to save a few extra bucks because the deep cell batteries manufactured with low build quality are not at all rugged and will hit you in the long run. All the deep cycle batteries I have recommended in this article are from reputable manufacturers. Even if you don’t find any of these batteries suitable for whatever reason, you can buy some other battery but never cut corners and go for one without researching the brand’s past reputation. What are the benefits of using a deep cycle battery? These are the advantages of using deep cycle batteries. They are lighter and less bulky than traditional lead batteries.There are no liquids required in deep cycle batteries.Low maintenance cost.Deep cycle batteries have less energy loss.These batteries charge at a fast rate.The batteries are durable and also have a long life span. How long does a deep cycle battery last? Deep cycle batteries are usually pretty long-lasting. You can use a deep cycle battery for up to six years provided that you take proper care of the battery and make sure that it is not getting damaged during the charging process. You can learn more about the maintenance structure of deep cycle batteries here. Can you use a deep cycle battery in your car? The clear answer to this bizarre but frequently asked question is a big NO. A deep cycle battery can not produce enough power to start up your car in the first place, and even if you manage to run your car somehow because of a small engine. You will not be able to make it far, and the battery will lose its life in a very short time, so it is not practical at all to use a deep cycle battery in your car. At what amperage rate should I charge my deep cycle battery? Usually, these batteries are charged at more than 6 amps. However, there is a different rating recommended for every battery, depending on its size. I would recommend you check the label on your battery to get hold of the precise ampere rating you should charge your battery and if you can not find the rating on the label, then look for it on the battery’s manual. Can you overcharge a deep cycle battery? No matter what type of battery you are using, overcharging is never a good idea. In fact, overcharging a battery can reduce the battery’s life, so a good idea would be to disconnect the battery from the source once fully charged. What is the difference between a car battery and a deep cycle battery? The significant difference between a traditional car battery and a deep cycle battery is that the deep cycle battery discharges very quickly. On the other hand, a car battery takes some time to discharge. What is an AGM deep cycle battery? Put merely, AGM batteries can handle high temperatures, and also do not discharge faster like other deep cycle batteries. You can read more about AGM batteries here. How to identify a bad deep cycle battery? The best and easiest way to identify if a battery is bad or damaged is by charging it thoroughly and then using it. If the battery gives the output that is guaranteed by the manufacturer, then it means that the battery is probably fine. Otherwise, it would be best if you reconsidered buying it. To learn more about how you can identify a bad deep cycle battery, you can check out this article in which this subject is discussed in-depth.

How to Wire Solar Panels in Parallel

If you are going solar for your home or business, it is important you know why and how to wire solar panels in parallel. Mark just switched to solar energy as an alternative energy option. With all the talk about renewable energy and climate change, he decided to ‘go clean and green’ with his home energy supply. He is finding it quite confusing to understand how to install the system in his home. Mark isn’t sure he needs to learn how to wire solar panels in any specific way: parallel or series. This is because to him, once the connection provides electricity, it’s all good. But is it? Well, I‘m so not sorry to burst Mark’s bubbles, and yours too if you think the same way. How you wire your solar panels matters. It is one of the most important variables in your solar energy system. It determines the overall efficiency of your system and also affects the kind of equipment you would have to buy alongside it. For one, your choice of inverter is based on its current and voltage rating depends on how your solar panels are connected: series, parallel or both. I’m sure you want the best option for your home, right? This is why you have to take note of this. For those who are still in the dark as to what solar energy, solar panels, inverters and all the jargons we have just discussed, no worries. I got you. Let’s take a run down through the basic concepts. Shall we? What is Solar Energy? Solar energy is the most available energy source on earth. It is clean, renewable and cannot be used up. Solar energy is increasingly being integrated as an off-grid energy option in homes and offices. This is well in line with the Sustainable Development Goals for 2030, which targets a substantial increase in the share of renewable energy in the global energy mix as well as an improvement in energy efficiency globally. Functions of a Solar Panel and Solar Energy System A Solar panel is a very important component of the solar energy system. It is responsible for trapping sunlight and converting it into electrical energy. The panels are made of Photovoltaic cells or PV cells. They are spread about on the surface of the panel boards. When sun rays fall on these cells, they are converted to electricity. So, the more the panels, the more PV cells are available to generate electricity. This electricity is Direct Current (DC). However, most of our commonly used electrical equipment make use of Alternating Current (AC). An inverter is then connected to the solar panels. Inverters are electronic devices that convert DC to the required AC needed to power electrical devices. So, we have our needed current and so our system is set up, or is it? There is still one more thing. We also need batteries in our system. Since we do not have the sun in full intensity at every time of the day (of course night comes and the sun retires to bed), we cannot guarantee that we would always be able to constantly produce a certain amount of electricity. Also, during cloudy days and also in the winter, the many clouds that form in the sky reduce the intensity of the sun reaching us. This means that much electricity can be generated from our solar energy option. This is where batteries come in. Batteries help us store the energy generated for future use. During the day when the sun is at its peak, you can use electricity in your home and be rest assured that by night, you’d still have electricity running so you can continue from where you left off the Game of Thrones episode before work. I see it like a kind of savings account or piggy bank, where you save energy for the rainy day (pun intended). How Do You Increase Efficiency and Power of Your Solar Energy System? To increase the efficiency and power output of your solar energy system, it is advised that you buy more solar panels. When you have more solar panels, the ideal thing to do is to connect them. This is pretty much obvious. Now here’s the catch. Well, panels are not connected in just any way. All the types of connection are aimed at achieving one main purpose: to increase power output. However, each method employs a different strategy in doing this. We will see this as we proceed. Ways in Which Solar Panels Can be Connected There are three ways solar panels can be connected: In Series CircuitIn Parallel CircuitCompound circuit (Series-Parallel circuit) Series Wiring of Solar Panels What does a series connection mean? Well, whenever electrical components are connected in series, the aim is usually to increase the voltage of the circuit. Solar panels connected in series produce a combined total voltage of the sum of individual panel ratings. What this simply means is that if you have six 12 volts 5 Amperes panels connected in series, your total output would be 72 volts 5 Amperes (Amperes is the unit used to measure current). Series connection creates a single pathway for current to travel, which means that all the current must flow through all the loads (in this case the solar panels) in the circuit. This is why the current remains the same up to the output. One other characteristic of series connection is that when the circuit is cut at any point, the entire system stops operating. This is pretty much expected since the same current goes through all as we have seen, so cutting off one is stopping current flow in the circuit. Solar panels have negative and positive terminals. To connect panels in series, you connect the negative terminal of one to the positive terminal of the next. This way you can increase power without altering the value of current being fed into the inverter. A very common example of series connection is your TV remote control. Also, a string of Christmas lights too is connected in series. The lights would not come on if one of the bulbs is burnt or not in place. Current path, remember? Parallel Wiring of Solar Panels Parallel connection, on the other hand, provides multiple pathways for current to travel within the circuit. This is the most common of all types of electrical wiring. I’m very sure your house is wired the same. Want to know how? Your home has a primary point where electricity enters into the house. It is from this point that electricity is fed to different sockets, bulbs, heaters in your home. When your friend comes visiting and you turn off the microwave after heating your lunch, it does not also turn off the TV in the living room. Like we saw in series connection, one point in the circuit going off means the entire circuit goes off too. This is not the case in parallel wiring. Since we have multiple current paths, one path going off does not affect the other(s). This means that parallel connection allows for redundancy, that is the system is more reliable as a fault in one path does not affect the whole. What Are The Advantages of Connecting Solar Panels in Parallel? Aside from improving the reliability of systems, parallel connections also aim to increase the amperage at the solar panel output. This means more current is being fed to the inverter. So, taking our example of six 12 volts 5 Amperes solar panels, parallel wiring would produce an output of 12 volts 30 Amperes. If a consumer has an inverter with a DC input rating of 12 volts, then such consumer only needs to supply 12 volts from the solar panel for the inverter to function. In this case, the consumer can connect in parallel to increase the amount of current, since the panels are wired to feed in 12 volts. This way, power can be increased without going past the voltage limit of the inverter. How Do You Wire Solar Panels in Parallel? Mike and Tim live together and have decided to get a solar panel. They split the bill and both agree to buy two panels each when they return from work. Later that evening, they discover that they have bought dissimilar solar panels. There has been an argument all evening, and it looks like work was tough on both of them. Well, I can help. Connecting Similar Panels If you are wiring similar solar panels in parallel, it is pretty much straight forward. You connect all the positive terminals together into one terminal and all the negative terminals together too. So, I could convince Tim to go back with his and get one that matches Mike’s and then, case dismissed. Connecting Dissimilar Panels If Tim is hell-bent on keeping his, and Mike is not bending, they have science to thank that they can reach a compromise. When solar panels have different wattage but the same voltage, they can be connected in parallel. Wattage just means how much power is measured. If the voltage is constant, we can connect them just as we did the first instance. What that simply means is that current is the variable factor in the different panels. For parallel connection, once the voltage is the same, we are good to go. Had they each bought panels with different voltage ratings, well one person would surely have to give in because there is no way we can connect them in parallel. Solar Panels Connected in Compound Well, Tim and Mike’s case didn’t fall into any of my predicted events. Tim bought two 6 volts solar panels while Mike got two 12 volts panels. Well, science to the rescue! We can connect the two 6 volts panels in series to get a 12 volts output. We can then connect this result to Mike’s 12 volts panels and everybody is happy. This is called compound wiring of solar panels. Conclusion. How to Wire Solar Panels in Parallel It is important that you as a home or business owner are able to connect your solar panels yourself and understand what each type of connection entails. Parallel connection is the most commonly used type of connection and we have seen why. You can now make informed choices based on what is available to you and enjoy your solar energy option with maximum Returns On Investments (ROI).

How to Stop LED Lights Glowing When Off

If you are stomping your head off trying to figure out how to stop LED lights glowing when off, then stomp no more because in this article all the solutions to fix the problem have been explained. Shoddily manufactured LED lights, when turned off, often produce an afterglow. I have experienced this unusual behavior with the LED lights in my home too. At first, I did not heed much. Soon the rather abnormal phenomenon started annoying me, especially during my sleep hours. Hence I was forced to find a solution to fix this soul-sucking problem. With some help from a few professionals of the field and some internet research about LED lights, I was able to identify and resolve the issue. If you’re also going through the same mind-boggling nuisance I was going through and also wondering how the heck are you supposed to stop already switched off LED lights from glowing, then you might want to keep reading because further in the article, I have explained all the fixes you can use to make the problem go away in as minimal technical terms as possible. What causes already switched off LED lights to glow? You must be left scratching your head while experiencing this weird occurrence of dimly lit LED lights for the first time, some are even left terrified, but before you draw any jigsaw conclusion, I am here to assure you that this is definitely not some devil’s work. In fact, this behavior is triggered in LED lights by not only one but many reasons. Reason 1 LED lights are said to consume 25-80% less energy than incandescent bulbs. Usually, this high-efficiency factor of LED lights causes them to flicker because there is always some amount of energy left in the circuit after you switch off the light. That little energy is enough to light up the LED for some time dimly. Reason 2 Poorly done or old electrical wiring also causes the LED lights to produce an afterglow effect. The obsolete wiring does not affect incandescent bulbs. Suppose you have recently switched to LED lights on old electrical wiring. In that case, it could be a possible reason for the afterglow in the LED lights. Reason 3 If you are facing the afterglow problem in LED lights near a staircase or a hallway, then there is a high chance that two conductors connected in parallel might be causing the lights to flicker. Reason 4 Sometimes the light switch that you toggle to turn off the LED lights switches off the neutral conductor instead of the phase. This causes a low voltage drop in the phase, which is enough to pull the afterglow in LED lights. Reason 5 White LED light can produce an afterglow for several minutes due to phosphor. Phosphor is used in bulbs to convert the original blue light emitted from LEDs into white light because phosphor is of yellow color and the combination of blue and yellow creates white color. Things You Will Need To Stop LED Lights Glowing When Off Here is a list of things you will need to follow the fixes given below in order to stop LED lights glowing when off: LED lights from a reputable manufacturerNeon indicator lightZener diodeCompact fluorescent lamp (CFL)Screwdriver Keep trying the next fix until you achieve success in removing the afterglow. Replace The Flickering LED Lights A lot of the time, the LED light itself triggers the afterglow effect due to its low build quality or incompatibility with the electrical wiring of your house. So the first and the easiest solution I will recommend you to try to stop the flickering of the light is to replace that old light with a new LED light from a reputable manufacturer. If the flickering goes away after replacing the previous LED light with a new one, consider replacing all the flickering lights of your home to get rid of the problem completely. Install A Neon Indicator Light You can easily get a pre-wired neon indicator light from any electronics store or online through Amazon or eBay for a couple of bucks. But if you are on a penny-pinching streak or just feeling too lazy to even shop online, then you can also take out a neon indicator light from your old or knocked down kitchen appliances like fridge, blender, and kettle. You can carve the neon indicator light out of the appliance just by using a small screwdriver. Neon indicators usually last years till they burn out, so you should be well and good with the neon indicator light that you just took out from your junk. Once you have acquired the neon indicator light, install it between the neutral and line. What this placement of indicator will do is that the neutral indicator will act as a voltage soaker and will now glow instead of the LED. The light produced by a neon indicator is far less interrupting compared to that of an LED bulb. It is essential to check the voltage range of the neon indicator you are placing to avoid any burnout. Use A Compact Fluorescent Lamp (CFL) We have already established that LED lights often illuminate an afterglow due to some voltage present in the circuit. This residual voltage can be soaked by putting a compact fluorescent lamp (CFL) in the circuit. In this way, LED light will not glow because of no extra voltage in the circuit. It is best to consult an electrician when dealing with electrical wiring and circuits because of safety concerns. However, please make sure to turn off the mainline powering your operation site if you are performing it yourself. Place A Zener Diode Zener diode is a diode created mainly to help the current flow in the reverse direction. This diode can help you in overcoming poorly grounded wiring. You can easily get a zener diode from an electronics store or online at a relatively cheap price. Installing a zener diode is rather easy too, and does not require any special technical skills. Once installed, the zener diode blocks all the charge by regulating the voltage when the LED switch is turned off. Thus, there is no afterglow produced in the LED lights. Install A Different Dimmer Sometimes, the electronic dimmer you are using for your LED Lights is not compatible with them. This usually occurs when you replace your old lights with new ones but keep using the old dimmers with the new lights creating a compatibility gap, which leads to this afterglow. In this case, the best solution is that you should install new dimmers that are compatible with your new lights. Do a little internet research about your current lights, and you will find the dimmer compatible with them. You can also opt for an electrician to do this job for you if you want it to be done professionally. Connect Extra Capacitors Typically, in long hallways and stairwells, two conductors are connected in parallel. Sometimes, the voltage carrying conductor induces some voltage in the other conductor. This little voltage drop in the conductor is enough to trigger the afterglow effect in a switched off LED light. To get rid of this phenomenon, you can simply install extra capacitors in your lights. The extra capacitors will seep all the unnecessary voltage drop, eliminating the flickering or afterglow in the light bulbs. You can easily purchase capacitors from a traditional electronics store or an online one. In Case Of Automated or Wi-Fi Controlled Lights In recent years, technologies like Smart home automation, IoT, and more have taken off. Now people do not use their hands to switch off stuff, but instead, they ask Alexa to do it for them. So if you are also living with modern tech and use some fancy Smart system to switch on and switch off your lights in your home, then the flickering LED lights problem in your home might be a little more complicated. The problem can be anywhere from your automated system to some deep electrical wiring connected to it. In this case, I would suggest you contact the company which installed the automated system in the first place. They would be able to diagnose and repair the problem in the best way possible because interrupting the deep electrical wiring yourself is dangerous and could also lead to electrocution. Summary. How To Stop LED Lights Glowing When Off People all around the world are switching from old bulbs to LED lights. The main cause of this switch is to take advantage of the low consumption and longevity factor of the LED bulbs. So if you are also one of those people who have switched from incandescent bulbs to LED lights, then your investment will definitely pay off. And in case you were regretful of your decision due to the flickering of the lights. No matter the situation, there is no need to fret anymore as this article contains all the solutions you can use to fix the afterglow effect. Now that you have all the solutions to solve the flickering problem, it is now time to get in action and do some work.

What Are The Drawbacks to Solar Tube Lighting

Solar energy enabled equipments have become a new trend in the market. Companies are discovering new methods of using solar energy and bringing them into use. One such technology is Solar Tube Lighting. These are also known as sun tunnel or light pipe. These light sources are perfect alternatives of skylights for getting the sunlight inside the room. These provide the natural way of brightening the dark areas of the house with natural or soft sunlight. Even during times when the sun is not visible, they are also accompanied by a photovoltaic technology which lightens the room anyways. The mechanism of solar tube lighting is relatively simple. These tubes are made of polished sheet metal or with highly reflective material. These materials channelize the sunlight into the house, amplifying the same as it passes through the tube. The solar tube lights come in a variety of sizes, ranging from 10 to 22 inches in diameter. They are also capped with a clear and weatherproof dome, thereby acting as small scale skylights. Solar tube lights gained popularity because of the benefits like free lighting and low to minimal rate of leaks. In comparison to skylights, solar tube lights have many additional benefits as well. These solar tube lights not only allow light but being narrow can be set up deeper into the rooms to bring more light inside the room. What Are The Drawbacks to Solar Tube Lighting? In spite of having so many benefits, solar tube lights are still not the best and the most efficient light sources to go for. Solar tube lights may be affordable and efficient in comparison to other alternatives. On comparing the pros and cons together, we concluded that cons outweigh pros. So, before buying solar tube lights, it is advisable to go through this list of cons as stated below. No view of the sky The ultimate purpose of solar tube lights varies and limits itself to small openings and then, amplifying the natural light to brighten the room. In this arrangement, the residents do not get any view of the sky which they would in the normal skylight. This arrangement can also bring a monotonous look in the house as well. On comparing this technology to skylights, it is observed that installing the latter not only allows ample natural sunlight to come inside the room, but also lets the residents enjoy the beautiful view of the sky. Not suited for every home Although solar tube lights take less roof space in comparison to the skylight, yet they take a lot of space in the house. This arrangement also reduces the chances of installing them using pipes in small homes as there is not enough space. So, it limits the usage of solar tube lighting in smaller houses. Therefore, the average family might not be able to afford that much space in their homes for the installation of the solar tube lights. Further, the design of the roof, i.e. the slope, the slant and such other factors also form a significant hindrance while installing solar tube lights. In comparison to skylights, another major issue is air circulation. This type of lighting is best suitable only for one-floor depths as the deeper you go into the house, the lesser light you receive. The reason being the longer the pipe, the lesser will be the light. Also, this depends upon a person’s personal choice as well. If a person wants to give preference to the appearance of the house, solar tube lights are not the best option. On the contrary, skylight boosts the appearance of the house leaps and bounds. The only source of energy It is essential to understand that the solar tube light’s source of power or energy is sunlight only. Though, there are some alternative light sources available but the only source of light in case of solar tube lighting is sunlight. On the days when there is rain, weather conditions are not favourable, not enough sunlight coming to the house, solar tube lighting is not feasible at all. In such cases, the residents will always have to look for alternative sources of light or be ready to be seated in the dark. High Upfront costs The cost of solar tube lighting is affordable and costs cheaper than other sources in the long run. But, the initial cost of installing and all costs related to it are relatively high. In case of big infrastructures where solar lights are to be installed, the initial cost of installing the solar tube lights is very high, raising overall price of the project. The average cost of installing one solar tube light technology in a house or building with a reasonable quality of the material is 500-1000, which by no means is cheap. Also, the other contributory factors pitch against the cost and make it expensive in the initial stages. There are a few modals of this technology which use rechargeable batteries in case the weather is not favourable, or there is less sunlight exposure of the building. These not only increase the cost of regular maintenance but at the same time counts as a major source of pollution as well. Not very much dependable The technology related to solar tube lighting has undoubtedly come a long way when it comes to bringing natural sunlight into the houses. But still, there is too much left which is outside our control. We have to rely on outside conditions for this technology to work totally. Also, every situation is not fit for the usage of solar tube lighting. Therefore, for the majority of projects, where consistent and strong light is required, the use of solar tube lighting is not advisable. This is because it can delay or slow the work at times. The technology is also not advised where the houses are built with extreme weather conditions. The conditions need to be just apt for the installation of lights into a certain house or building. Further, upon the installation of the solar tube lights, if any problem or emergency creeps in rendering the technology, these lights cannot be opened and are even difficult to maintain. Also, there may be times when water condenses at the coverings, affecting the light coming through the tubes and also disrupting the same. Difficult to install The solar tube lights are not easy to install. If by chance a wrong type of light or tube is chosen for a house, it might not serve the purpose it is installed for. In other words, when installed improperly or with some flaws, these lights may act as a channel for continuous leakage from the rooftop. The professional also charges a hefty amount for setting up the lights, adding further to the costs. Does not prevent UV light One of the major drawbacks of installing solar tube light is that it does not prevent the harmful UV radiations from entering the house. Whereas, the skylights have a special feature where they are enabled to stop the UV radiations from entering the house or building. These radiations can be harmful to the people being in contact with such radiations. Conclusions In the end, after going through all these cons and weighing them in comparison to the pros, it becomes evident that the cons outweigh the pros. It is also important that investors remain aware of what they are investing in especially when it comes to the houses. Though, this technology has come a long way in making energy-efficient, cheaper and more sustainable options, yet there are many more strides that need to be taken care of in this field to make it as a part of every household and be more reliable and consumer-friendly.
