BatteryCare Battery calibration Windows 10



When considering laptops, performance is far less of a concern than with desktop. Most people are looking for a machine that can be used for as long as possible without the need to track down a power supply. As such, laptops that offer the longest battery life tend to be the most popular, and BatteryCare is a free tool that can be used to look after your battery and help to improve its longevity.

For older batteries, one of the most useful things it was possible to do to your laptop battery is to let is completely discharge and then recharge from time to time. This helped to maintain the performance of the battery and ensures that it is used efficiently and last for as long as possible between charges.

BatteryCare can be used to perform a full discharge of your battery, not necessarily to help improve performance, but more to calibrate the battery so that time estimates can be more accurately reported. The program also provides a great deal of information about the battery you have installed, so should you ever need to buy a replacement, you will have all of the relevant details to hand.

BatteryCare will also provide information about precisely how long your battery will power your laptop – this is a useful feature as many machines will only reported the percentage of charge that is remaining. Extra options include the ability to monitor hard drive and CPU temperatures as well as a simple means of switching between power profiles depending on the power source that is in use.


A handy little tool that keeps you informed about the state of your battery, with the calibration features meaning that you can trust your battery to last as long as it claims.

How to calibrate Dell laptop Battery for accurate battery life estimate.

Your laptop shuts down without a warning, that’s annoying.

Dell laptops sometimes have battery calibration issues.

This is a problem as you don’t actually know how much charge your battery has left.

It could show 100% and the next minute your laptop switches off making you lose what you were working. But this is an issue that can be easily fixed by calibrating you dell laptop battery so it measures its capacity accurately.

Fortunately battery calibration is an easy task you don’t need a computer scientist, you can do it yourself.

Basically how you do it is, you drain the battery completely then recharge it to its full capacity which allows the sensors to measure more accurately how long the battery actually lasts.

Calibrate Dell laptop battery

First you need to change your power plan settings so it allows your battery to drain without interruption, to do this

  • Right Click on the battery icon in system tray.
  • Select Power Options.
  • Then click on change plan settings.
  • Set Turn off display to Never and Put the computer to sleep setting also to Never.
  • Save changes.

Advanced Settings

  • Next click on Change advanced power settings.
  • On the list of devices select Battery, its the last option on my Dell latitude E7480.
  • Click the Sign to expand menu.
  • Set Critical battery action to Hibernate.
  • Then set Critical Battery Level to 5% or as low as you can set.
  • Now click apply then okay.

Now you can let the battery drain, you can be using the laptop while the battery drains.

batterycare, battery, calibration, windows

If you are not using the laptop make sure its not set to sleep after a certain period of time as this might mess up with the correct battery measurement.

When the laptop hibernates because the battery is too low let the battery cool down. Give it at least an hour or 2 before you plug it in to charge.

Now charge the laptop to its full capacity.

Your laptop should have a more accurate battery reading now.

Does battery calibration damage the battery

Laptop batteries gradual wear out with normal usage. Frequently calibrating your laptop increase battery wear and is not necessary on most modern laptops.

Ideally you should calibrate your battery when you feel that its really no longer measuring its capacity correctly.

How often should I perform battery calibration on dell laptop.

You maybe wondering how frequent is too much, when it comes to calibrating your laptop battery. This depends on a number of things.

For example the frequency of use, battery age, the type of battery, heat etc

As a rule of thumb you should not be calibrating your battery more than once in atleast months as this increases the battery wear. As I said above most modern laptops do not need battery calibration as much as the older ones.

If your battery continues to give you problems, the battery might be dead or dying. You can run a diagnostic test as described in this article on Dell diagnostic. If you get an error code look up the error code as described in the article I linked to above.

If you need a replacement, you can get a new battery its cheap here

Should I calibrate new laptop battery

There is no need to calibrate the battery on a new laptop. But that’s on the assumption that a new laptop means a new battery.

Calibrating is only necessary when you think your laptop isn’t measuring your battery capacity correctly.

Otherwise there is no need.

Calibrate Laptop in BIOS

Some laptops come with built in calibration software. If that’s the case you will see the option in the BIOS menu as show in the image below.

To calibrate your laptop using built in software.

  • Shutdown the laptop
  • Press the power button to turn it on again
  • Immediately press the F2 key to enter into BIOS
  • Navigate to the power tab
  • Select Start Battery Calibration.
  • Follow the prompts to calibrate your laptop battery.

Power CFG

Another important thing you can do is to check your battery health. This will help you see if the battery needs a replacement or not. It also shows you how much wear the battery has.

You can do this by generating a Windows battery report

To generate the a battery report in Windows

  • Press the Windows key and type “Run” without quotes
  • Right click on the Run program and select run as administrator
  • Click yes if it request permission.
  • On the Windows terminal the opens type the command powercfg /batteryreport
  • Now press WindowsR and type the following path on the input box that appears: C:\Windows\system32\battery-report.html
  • It should open the report on default browser for example chrome

Hope this information was helpful in making your laptop usage more productive.

How to calibrate your laptop’s battery and fix inaccurate wear info

The issue I’ve been coming across recently seems to be mostly with Dell’s XPS line of laptops, though it can certainly affect others: My new XPS 13 9370, XPS 15 9575, and XPS 15 9570 showed 8, 14.5, and 10% battery wear out-of-the-box, respectively (a battery wear of 10% means that the battery is only able to charge to about 90% of its rated capacity).

Normally, batteries will only show this much wear after a year of heavy usage, and it isn’t something you should accept in a new laptop. I realized something was up when every single XPS 15 I checked out new had around 10% battery wear reported, however. Warning: lithium-ion batteries should generally not be fully discharged as this cause real wear to the battery. Thus, battery re-calibration should only be conducted sparingly when you suspect a problem with the way the battery reporting its capacity.

Battery calibration hasn’t been much of a necessity since lithium-ion batteries got so much smarter over the past few years. Thus, even as someone who considers themselves to know quite a bit about notebooks, properly calibrating the battery in my new XPS laptops (showing incorrect wear percentages out of the box) was something I had to do a bit of reading up on combined with some trial and error to get right, and so I thought I would write a brief guide on how to do it right the first time.

Following this protocol, I was able to reduce the reported wear levels significantly to the low single-digits and recover a good deal of battery life.

Checking your battery’s reported wear

Before bothering with a calibration, it’s necessary to check the reported health of your battery. If your battery is new and showing less than 95% of its original capacity then it is probably worth recalibrating.

Go to the Start menu and search “cmd” to show the Command Prompt (PowerShell will do fine as well). Right-click the search result to run your choice of app as an administrator. Copy and paste the following line into the command line: powercfg /batteryreport

The battery health report will be output to the Windows\system32 folder by default.

Copy the directory path and paste it into your favourite web browser to view it. Once it opens, you can scroll down a bit and you should see your battery’s health as a function of design capacity (rated capacity) and full charge capacity (actual amount the battery reports it is able to hold).

After calibration. Before calibration, the full charge capacity was only 87,000 mWh, or less than 90% of advertised.

By doing some quick math you should be able to see how healthy your battery currently is. Technically it is not good to fully charge and discharge a Li-Ion battery often (which is what calibration requires), so if your battery is not new and the wear percentage seems reasonable, it may be best to leave it. If you see only 90% of capacity on a new laptop, however, then this guide will definitely help.

Step 1:

First, you will need to let your laptop charge to its “full” capacity. OEMs like Dell and Lenovo allow the user to set charging-thresholds on the battery in order to preserve the battery health (this is a very good practice that I encourage all OEMs to follow). Thus, to charge the laptop fully, you’ll need to find that setting and set your charging threshold temporarily to 100%. On XPS machines, this is done through Dell Power Manager or the BIOS.

You’ll need to set the charging behavior to “Standard” or change the slider manually to 100% to complete the first step. Once this is done, make sure your laptop is plugged-in and allow it to charge completely.

Step 2:

Next, you need to let the battery completely discharge until forced shut-off (not just hibernation). There are a few ways to do this, but my favourite method is the simplest: Restart the laptop in BIOS mode, then go out of the house for the day. With this method, you don’t need to worry about the laptop going to sleep or hibernating as these features are not enabled when viewing the BIOS. Additionally, power-saving states are not enabled for the CPU when in the BIOS either, meaning the laptop will run down significantly faster than it would in Windows under normal usage.

You could also use the laptop normally and let it run down until it automatically hibernates, then leave it in BIOS as described above as well. This requires your turn off all of the sleep and hibernation timers in the Power Options control panel first, however.

Step 3:

WAIT. Do not immediately charge the laptop; be sure the laptop has been sitting cool and unplugged for 3-5 hours before the next step. Failing to perform this step can result in making your reported battery wear worse.

Step 4:

Plug the laptop in and let it charge to maximum uninterrupted. You should be able to use the laptop in Windows at this point, but I let it charge in BIOS out of superstition. When you generate your battery report again, you should (hopefully) see a much higher rated capacity for your new battery.


That’s it! Using this method I was able to reduce my 9575 reporting 14% wear down to 4%, my 9570 reporting 10% down to 3.8%, and my 9370 reporting 8% wear down to 4%, and I hope it fixes the problem for you simply as well. As always, try to practice good battery care to prolong their lives: Keep them cool, don’t run them dry, and don’t charge them to maximum often.

Absolutely — the lack of QC is, imo, one of the main reasons why companies like Apple can exist despite being noncompetitive in almost every other arena. I would guess that whoever has been supplying their batteries is the same company for all 3 XPS machines, thus why they all have incorrect wear/capacities.

Absolutely! Apple charges for looks and brand name, rather than functionality or features. case in point is the MacBook, which has seen nothing by way of change in donkey’s years! I used a MacBook Pro (15) way back, unning on Panther or something. Sure, the Wi-Fi connected before I knew what was happening, the Machine was beautiful (though obscenely heavy compared to my IBM ThinkPad) and the illuminated Apple Logo was cool… However, I missed my favourite Apps, missed my favourite Games (I used to be something of a gamer back then) and the familiar Menus and Colours of Windows!! After 6 months usage (it was provided by the Office), I returned it for a HP. I was soo relieved! The guy who was allotted my MacBook was pleased as punch too, as I had maintained it scratch-free, in mint condition!! That was the last I ever wished for an Apple – Phone, Pad, Laptop of Desktop!!

Hello, I have a 10 months old premium Lenovo notebook (Yoga c930). First battery was replaced after just 2 months with wear level of 6%. Second battery is already at 26% wear. I have tried recalibration, but Lenovo is kind of now ignoring me because Lenovo Vantage says battery is in Good condition. I guess they dont care for wear level! This battery is inside for 6 months and it seems I have lost 1/4 of its capacity already. In my opinion this is just crazy, especially for such expensive device. Any Комментарии и мнения владельцев?

That sucks. I’d press for a replacement if that’s included in your Warranty package, 26% wear in half a year is awful.

I plugged in my battery and overslept, today. When I woke up my battery’s wear level went from 0% to 3%. I have a new zephryus g14 bought a month ago. Shall I follow this tutorial or should I wait to see if the wear percentage in the next couple of days increases?

I think that’s small enough that it’s probably accurate and there’s no need to follow this guide at this time.

worked for me perfectly on my new xps 9570. from 87 to 93mWh. If i repeat this process, will i get to 97mWh at some point or is 93 the best result i can get for my battery and it will only get worse from this point?

As far as I know, it shouldn’t get worse, so you could try it one more time, but it won’t probably do much. 93/97 is not bad though. Update: Also see Kirikshi’s the reply below.

That is not true, as any Li-Ion battery is very susceptible to complete discharge. It is said to resist quite low (1-2 dozens) of complete harsh discharges (as in the article) till its completely dead in terms of residual capacity. So, this experiment (albeit it can help with the calibration) is not a fortnight trick. No one promised that following complete discharge will damage battery (decrease capacity) less, than it rescales the calibration. Another reason not to risk – Li-Ion batteries show thermoelecric effect – voltage of a unified battery depends on temperature. (example: As a result, if you drop your charge to critical level and afterwards your laptop battery cools down – it goes below critical level, damaging the cell. All of this means that the procedure, even if it leads to calibration with winning around 5-10% of capacity, shouldn`t be implemented often (more than 4-5 times for the battery life).

That is correct — I hoped I made it clear in the article not to do this unless your battery should be brand new but is showing unusual wear (such as the case with many Dell laptops).

Thanks, you’re right, I was only suggesting performing this one more time. I’ll edit the initial reply to make it more clearly.

Turn on the computer and immediately press the F2 key repeatedly, once every second until the HP PC Hardware Diagnostics UEFI menu displays. Click Component Tests in the main menu.

Thanks for this article. I’m here because of my Dell XPS 15 9570, FullHD, 97Wh. The first weeks the battery last about 8-10h with my use case which look like this: 60% Videos/Streams via LAN 25% Office Work 10% Music via external speakers 05% Gaming After about ten weeks, the battery only last about 4-6h with the same use case. So, I just have done the cmd step, and the battery has a full charged capacity of 77Wh, compared to 97Wh! After ~twelve weeks just 80%! of the capacity is left. I hope with the steps the capacity will increase again, if not this was the first and last time buying such an expansive notebook from Dell…

So, after 2.5 days, and about 6.times repeating the steps 1-4, the battery is now mostly healed. From 77Wh to 89Wh in just a short time. I also know what one problem was. Like with the smartphones-batteries, I thought it would be okay to charge my notebook at about 15-20% up to 97-100%. But this notebook looks like it does not work with this way of charging. But, in my opinion the notebook should handle this kind of charging in a better way. I mean, I can not wait everytime to charge up to 100% and then leave my flat. Thank you for this steps, saved my money for a new battery ;).

Just repeated this process 3 times with my 9575, but unfortunately my battery went from 13% of wear (laptop is only 4 month old and was shipped with 5.7%) to 23%. I discharged it from the full state in BIOS. Then I waited for 5-13 hours to discharge more and then didn’t touch it when it was charging. What am I doing wrong? BTW the time I switched from charging from max 94% to 100% (and started using Manjaro Linux) I saw a drop in a capacity to that 13%, I’ve previously mentioned. BIOS 1.2.0 (latest)

Hi, I ve been checking the actual capacity, and it fell from 96000mah out of the box, till 88000, about 2 months later. The weird thing is that now after a full charge, I disconnect it and it inmediately drops from 100 to 95, or 98 in today’s case. I did this calibration yesterday but didnt solve the problem!

That sounds like it’s what you’re battery’s actual capacity is. It isn’t great but not malfunctioning yet

My 9575 on 1.2.0 BIOS (don’t know if that matters) after 3 of these procedures went from 13.5 to 21.5 battery wear? I charged the laptop to 100% then opened BIOS and sit there till it powers off. Then I waited 5-10 hours and plugged back in to charge to 100%. Every time I opened the OS the battery capacity slowly had gone out. What am I doing wrong? Laptop is only 4 month old and was shipped with 5.7% wear.

sorry for the late reply. I would suggest calling for a new battery before your laptop is 6 months old – you may really have 21% battery wear, and batteries are usually only covered for the first 6 months of warranty. Tell them it’s at 21.5% wear and it’s running out much too soon, and they should help you out with a new one.

I did so as you mentioned.but the wear level increased to 20% from 14% dell 4 cell 41mah battery purchased before 1 week. At first recharge wear level was 5% and my lappy automatically goes to hibernate at 37% and suddenly it show 8% then after wear level increased to 14 and now it’s 20. Backup is approx 3 hours all settings are normal. Did I got the defective piece…it’s nearly 4 months old manufactured as mentioned on box. I conslulted dell they took several tests and all tests were cleared successful…and told me to charge discharge some more cycles for stability. Should I opt for replacement as the retailer gives me full 1 year warranty at his shop. Can you suggest me what should I do….thanks

Sorry for the late reply! If you have a new battery with 14% wear that re-calibrated to 20%, I would return it to the shop indeed.

There is no way to keep the 9370 (XPS 13) from turning off at critical battery level (which cannot be set lower than 2% in advanced power settings) even if I am in BIOS. I keep turning it on and then it turns off after booting up again and again. I don’t know if this impacts the calibration process. I calibrated it a week ago and gained 10% capacity (design is 52Wh and it had increased to nearly 48Wh) but three days later it dropped to 41Wh so I hesitatingly, as attempting it once more. One other question, the 9370 BIOS allows me to set charging between 50 and 90%. But when I do that it stops at 90%, gives me the message plugged in not charging but never leaves 90%. So it doesn’t discharge down to 50% ever. Turned that off after a day setting at 90%. Is this a problem with Modern Sleep or can I change something in registry? I tried asking this on Dell without any luck.

I did the steps from 1 to 4 for my XPS 9570 and I managed to decrease the wear from 10% to 4,3% (from 87MWh to almost 93Mwh). It is crucial to leave you laptop discharged for 3-5 hours before charging it again to full capacity.

Hi, First of all I would like to thank you for the guide. Unfortunately it has not been helpful for me. The battery in my X1 Extreme went down from 75MWh to 72MWh. Its design capacity is 80MWh and it only has 25 recharge cycles so far. I also mostly use the laptop plugged in with a 80% threshold activated. Does this mean my battery is faulty and should I file a claim for a new one? Or should I try to recalibrate the battery one more time? Thanks so much, your support is greatly appreciated.

Batteries are so mercurial that I almost feel like recalling this guide. I’ve successfully re-calibrated batteries with this process quite a few times, but mostly from Dell. Lenovo seems to play on the conservative side with their firmware (batteries included) I think, in order to keep things more reliable. Just a theory. After 25 cycles and you’re at 72Wh though, I’d try recalibrating once more (leave it a good while to cool off before charging) before trying for a new battery.

Hi Douglas, Thanks so much for your quick reply. Will recalibrate one more time before trying for a new battery then. Thank you!

I would maybe edit the guide to add a big bold warning at the beginning along the lines of: Generally this process should only be performed once, and only if you believe you believe the indicated degradation is inaccurate. It will NOT improve a legitimately worn battery. I would hate to see the guide recalled since it is a great resource.

Hi ,two days before I had a sudden battery failure. The first time that I did the recalibration to the battery following these steps I had a 0% wear and after 8 months of use my battery was at 94WHr / 97 Whr. After changing the battery I tried yesterday to calobrate my battery but I dont remember what I have done in the past. So yesterday I let it fully discharged after replacing the battery. Then recharged to full after 5 hours. Today I used the laptop and I let it to fully diacharged again and I charged it to 100% but the battery is 93Whr / 97. Will be a problem if I repeat the steps again – one more time ?

Worked for me the first time. In the very beginning I could get some wear levels going down. But now after repeating the process, every time I let the computer completety discharge in BIOS it only gets worse. I am repeating the process each month and my wear level that was at 6% is at 16% now. So I won’t do it again. Ever…

Don’t keep doing it. It’s likely that is the actual wear on your battery. This process is takes a toll on your battery and I wouldn’t do it unless you have a reason to think the battery wear is inaccurate

Worked great on my Dell Precision 5530. Went from Full Charge Capacity of 87,500 mWh (out of 97,003) to 93,275, or 9.8% degradation to 3.8%. Big improvement. Thanks for writing this up.

My battery have 92.5% health out-of-the-box ( vostro 7590 ). How do you think – will dell change this battery?

Top 6 Ways to Fix Windows 11 Laptop Showing Wrong Battery Percentage

The battery percentage reading on your Windows 11 laptop can be helpful to you plan your work and avoid unexpected shutdowns. However, if the battery level displayed on your Windows 11 laptop is inaccurate, it may result in the loss of data and your work when your laptop shuts down abruptly.

It’s rather odd that the battery percentage on your Windows 11 laptop isn’t changing or displaying incorrect information. However, you can change that by ensuring to view an accurate (or near accurate) information about battery levels on your laptop. We’ve compiled simple and effective solutions to fix the issue quickly.

Perform a Power Cycle

Performing a power cycle clears residual charge from the laptop’s capacitor and resolve any common issues. If the incorrect battery percentage on Windows is just a one-off or occassional glitch, this should take care of it and save you a lot of time.

Step 1: Press the Power button to turn off your laptop and unplug all the external devices.

Step 2: Remove your laptop’s battery. Next, press and hold the physical power button for 15-20 seconds. That’ll get rid of any residual charge from your laptop’s internals.

Step 3: Re-insert the battery after a minute and power on your laptop. Then, check if Windows displays the correct battery percentage.

Calibrate Your Laptop Battery

Calibrating your laptop battery is another option to rectify inaccurate battery readings. Before that, you’ll need to adjust the power management settings so they don’t interfere with the battery calibration process.

Step 1: Press the Windows key R to open the Run dialog box. Type powercfg.cpl in the text field and press Enter.

Step 2: In the Power Options window, click ‘Change when the computer sleeps.’

Step 3: Set all the drop-down menus to Never.

Step 4: Next, click on ‘Change advanced power settings.’

Step 5: Double-click on Battery and then Critical battery action.

Step 6: Under the ‘Critical battery action’ section, use the drop-downs to choose Hibernate for On battery and Plugged in options.

Step 7: Next, double-click on the Critical battery level and use the drop-downs to set the values to as low as possible. Then, hit Apply followed by OK.

After you’ve configured the power management options, you can calibrate your laptop battery by following the steps below.

Step 1: Charge your laptop battery to 100% and leave it plugged in for at least a couple of hours after that.

Step 2: Unplug your laptop and start using it. Allow your laptop to discharge fully and shut down on its own.

Step 3: After your laptop runs out of power, plug it back in and charge the battery to 100% again.

Following this, your Windows 11 laptop should give accurate battery readings.

Run the Power Troubleshooter

The Power troubleshooter in Windows can automatically scan your system for any battery-related issues and resolve them. It will optimize power management settings on your laptop and make any necessary changes.

To run the Power troubleshooter on Windows:

Step 1: Click the Windows Search menu, type in troubleshooter settings, and press Enter enter to open Troubleshooters in the Settings app.

Step 2: Click Other troubleshooters on the right pane.

Step 3: Click the Run button next to Power.

batterycare, battery, calibration, windows

After running the troubleshooter, observe the battery percentage readings on Windows 11 to note if they show reliable numbers.

Re-Enable Battery Adapter

Battery adapter on your computer works as a bridge of communication between your laptop’s battery and Windows. If this adapter is experiencing issues, Windows may fail to derive necessary details and display an incorrect battery percentage. Here’s how to fix it.

Step 1: Press the Windows key S to open the Windows search menu. Type device manager in the box and press Enter.

Step 2: Click the arrow before Batteries to expand it.

Step 3: Right-click on the battery adapter and select Disable device.

Step 4: Right-click on the battery adapter again and select Enable device.

Restart your computer to apply the change.

Update or Reinstall Battery Drivers

If restarting battery drivers doesn’t help, it’s time to update them. The idea is to fix any issues caused by outdated or malfunctioning battery drivers.

Step 1: Right-click on the Start icon and select Device Manager from the list.

Step 2: Under Batteries, right-click on the battery adapter and select Update driver.

From there, follow the on-screen prompts to finish updating the driver. If the problem persists even after that, it’s likely that the battery driver is corrupted. In that case, you can try uninstalling the driver using Device Manager.

After you remove drivers, restart your PC to allow Windows search and install the battery driver. Then, check if the issue persists.

Install Windows Updates

Usually, Windows downloads newer updates automatically. However, if you have disabled automatic updates on your device, you might need to look for newer updates manually. If the issue with the battery reading is occurring due to a bug, installing newer updates will most likely fix it.

Press the Windows key I to open the Settings app, navigate to the Windows Update tab, and click the ‘Check for updates’ button at the top-right corner.

Download and install any pending updates and then observe the battery readings of your laptop.

Accuracy Guaranteed

One of the methods mentioned above will get Windows 11 to display the correct battery percentage. However, if nothing works, there might be an issue with the battery itself. In that case, generating a battery report can help assess the battery health details and determine whether a replacement is necessary.

The battery is one of the most important components of a laptop, and you don’t want anything damaging your laptop battery. Why?

It provides the power necessary to take your device with you on the go and work or play for hours without being tethered to an outlet. But, like all other components/gadgets, the battery can suffer from wear and tear over time.

In this article, we will explore what factors are damaging your laptop’s battery in Windows 11 and how you can prevent them to extend its lifespan.

Common Causes of Laptop Battery Damage

Several common factors can damage your laptop’s battery in Windows 11. Understanding these causes is the first step to preventing them.


One of the most common causes of battery damage is overcharging. When you leave your laptop plugged in for too long, the battery can become overcharged, decreasing its lifespan. To avoid overcharging, monitoring the charging process and removing the power cord when the battery is fully charged is important.

High temperature

High temperature is another factor that can cause battery damage. When a laptop is used for long periods of time, it can generate a significant amount of heat, which can cause the battery to overheat. This can lead to a decrease in battery life and performance. To prevent this, make sure your laptop is well-ventilated and avoid using it on soft surfaces that can block air flow.

Power surges

Power surges can also damage your laptop’s battery. A sudden increase in voltage can cause a surge in current, which can cause damage to the battery and other components. To protect your laptop from power surges, consider using a surge protector.

Running too many programs simultaneously

When you run too many programs simultaneously, your laptop has to work harder, which can generate more heat and put more strain on the battery. To avoid this, close any programs you’re not using and optimize your laptop’s performance.

Installing outdated drivers

Finally, outdated drivers can also damage your laptop’s battery. Drivers are the software that helps your operating system communicate with hardware components, including the battery. If you have outdated drivers, your laptop may not be able to communicate with the battery effectively, which can lead to performance issues and battery damage.

Effects of Battery Damage

When your laptop’s battery is damaged, there are several effects you may experience.

Decreased battery life

One of the most obvious effects of battery damage is a decrease in overall battery life. When your battery is damaged, it may not be able to hold a charge as well, which can result in a shorter battery life.
