If you plan on doing DIY projects inside or out of your home, there’s a good chance a drill set will come in handy. These sets come with a drill—naturally—bundled with accessories like drivers, extra batteries, and a case, so you have everything you need to use the tool in as many situations as possible while keeping it properly maintained. There’s nothing wrong with getting a drill and picking up these accessories over time, but having a set is a lot more convenient.

Plus, chances are if you’re looking for those accessories, the need is immediate rather than imminent, so it’s better to be prepared than sorry. Plus, with proper care, these drill sets are going to last a lifetime, so picking one up is well with the investment. The best drill sets will save you time, stress, and money, especially if you begin taking on smaller home repairs rather than paying someone to do them.

How we chose the best drill sets

We had two guiding principles when researching the best drill sets and ultimately selecting the five you’ll find below: personal needs and cost. All of the drill sets below are suitable for common tasks like hanging a TV on a wall and drilling a few pieces of wood together to build furniture, but the accessories they come with—and their price—are different.

The best drill sets: Reviews Recommendations

The best drill sets will allow you to tackle the widest number of jobs and complete them in the shortest period of time. The accessories that accompany the drill should complement it and be useful on a regular basis rather than superfluous. You shouldn’t ever have to upgrade your drill set, so consider each of our recommendations before selecting the correct one for your needs.

Best overall: CRAFTSMAN V20 Cordless Drill Combo Kit

  • Drill power: 3,400 RPM
  • Weight: 4.4 pounds
  • Accessories: Two batteries, carrying case, 85-piece drill bit set, impact driver

If you want to fill out your entire power tool library in one fell swoop, you should start with CRAFTSMAN’s V20 Cordless Drill Combo Kit, which is the only drill set we’re recommending with two tools. The star of the show is its 20-volt drill, which can rotate at speeds of up to 3,400 rotations per minute. It’s the most powerful drill you’ll find below, and while you’ll have to pay a little extra, it’s absolutely worth the investment. The only downside to the drill’s immense power is its weight—it’s roughly a pound heavier than our other recommendations. If you don’t mind holding a heavier power tool, you’ll appreciate the oomph because it can help you get jobs done more quickly.

On the accessories side of things, this set comes with all the essentials plus a carrying case and impact driver. An impact driver may look like a drill, but it wraps around a screw or lag bolt to rotate them. An impact driver won’t require constant alignment (it’s easy for a drill bit to slip off a Phillips or flat-head screw if you’re not careful, which can lead to damaged furniture) and is best suited for heavy-duty tasks. This isn’t the type of tool you’re likely to have in your garage already, and while you may be unfamiliar with it, its applications will become apparent as DIY projects arise. Both of CRAFTSMAN’s tools have an LED light, which will help you use them in dark areas—think attics or nooks and crannies in a basement or garage—which is a nice little touch that makes a lot of difference.

If you don’t mind spending a little extra and know you’ve got a bunch of upcoming home projects, this is the one drill set we’d recommend. Even less seasoned repair people will appreciate having an impact driver on hand just in case.

Best cordless: DeWALT DCD771C2 20V MAX Lithium-Ion Compact Drill/Driver Kit

  • Drill power: 1,500 RPM
  • Drill weight: 3.64 pounds
  • Accessories: 45-piece drill set, battery, charger, carrying case

DeWALT’s cordless drill set includes everything you need to get started on home renovation projects without worrying about wires. The drill itself is powerful and lightweight with a textured body that makes it easy to grab, but it’s the included accessories that make this set worth picking up. DeWALT has bundled its drill with a pair of batteries and charger, so you can use the drill continuously for several hours without having to pause in the middle of your job. This is incredibly important if you’re on a tight deadline.

The included bit set ensures you’ll be ready to work with screws of all shapes and sizes, and its hardshell case clasps shut to keep them protected and prevent them from coming loose in your drill bag. One of the reasons we rate DeWALT’s power tools generally—and drills specifically—is the wide variety of accessories you can use with them. Our favorite for this drill is an optional USB-C charging kit, which allows you to use the same power adapter you use for your laptop with your power tools.

The primary reason you should get a cordless drill is the convenience of using it without worrying about where your outlets are or whether you’ll run out of juice. DeWALT’s decision to bundle two batteries with this drill set makes it the top choice if portability is your primary concern.

Best for metal: BLACKDECKER LD120VA 20-Volt Max Lithium Drill

  • Drill power: 750 RPM
  • Drill weight: 3.98 pounds
  • Accessories: 109-piece bit set, battery, charger
  • Drill is designed to prevent screws from stripping
  • 109-piece bit set is robust
  • Interchangeable battery with other tools

If you’re going to work on drilling projects that involve metal, you’ll need a drill set with bits designed for that job. The 109-piece bit set BLACKDECKER includes with its drill set that is designed to be used specifically for metal, wood, and plastic. This drill may not spin as quickly as our other recommendations, but a variety of steel bits will allow you to easily make holes between one-eighth of an inch to three-eighths of an inch in diameter and several inches deep. In many cases, piercing your material first will make it easier to drive a screw through it.

Additionally, the drill in this set has a 24-position clutch, which means you can adjust its maximum rotational speed to avoid using too much power when it’s unnecessary. You won’t need to change this setting when working with metal, but may want to tone things down when working with thin sheets of wood or particleboard. We like that BLACKDECKER’s extensive bit set comes with its own hardshell carrying case, so you’ll never lose a bit, but wish the company had thought to include a carrying case for the drill and its accessories too.

While we’re recommending this drill set on its own, it’s nice to know that BLACKDECKER standardized the battery on many of its handheld power tools, which makes them interchangeable. If you begin to build up a full garage or tool room’s worth of tools, this will become a big advantage.

Best corded: DeWALT DWD115K 45-Piece Titanium Drill Bit Set

  • Never needs to be charged
  • Fast speed
  • Identical bit set to our cordless recommendation

This corded drill set from DeWALT carries over most of the features we liked about its cordless model—including the same great bit set—but you never have to worry about it running out of juice. In fact, this drill’s maximum speed is over 65% faster than its cordless cousin. However, carrying a cable around has its costs, namely a substantial increase in weight and being tied (literally) to an outlet. It’s worth noting the drill itself isn’t heavy, but you’ll also be carrying the weight of its cord around you everywhere.

On the upside, this drill’s svelter shape makes it a little easier to get into tight spaces a full-sized cordless drill may struggle to access. Its additional power will come in handy if you’re drilling through particularly hard surfaces, and it’ll be able to run at its top speed indefinitely because DeWALT didn’t have to worry about battery life when designing the drill. If you understand the tradeoff inherent in getting a corded drill, this set from DeWALT is a fantastic choice.

Best budget: Litheli Cordless Drill Set

  • Drill power: 1,300 RPM
  • Drill weight: 3.5 pounds
  • Accessories: 16-piece bit set, battery, charger, belt clip, magnetic extension bar

Litheli bucks the trend of power tools being pricey with its feature-competitive-yet-cost-effective drill set, which includes a battery, belt clip, and an assortment of drivers. The drill’s power is right in line with what we’ve come to expect from a cordless model, and it’s the lightest one we’re recommending—though only by about a tenth of a pound. The included accessories are also similar to what you’d expect from drill sets that cost a lot more, so where did Litheli cut corners?

Thankfully the answer isn’t technical—there isn’t a must-have feature that this drill lacks—but there are some nice creature comforts you won’t find in this set. The included bit set doesn’t have a case, which means they could get lost if they were dislodged from their little labeled holder. This is even more awkward for the larger bits that have no holder at all. Similarly, Litehli doesn’t include a carrying case with its drill set, which also increases the odds of something getting lost.

On the other hand, this drill set costs 50 (it’s currently 10 off thanks to an Amazon coupon, but there’s no telling when that expires), and a really solid power tool deal. Our recommendation is to pick up a generic, inexpensive tool bag to solve this problem. Yes, you’ll have to get a third-party accessory to complete this drill set, but you’ll still save a big chunk of change compared to our other recommendations.

What to consider when shopping for the best drill sets

Drill sets come in a variety of configurations, but below you’ll find the factors that are most important in helping you find the right one for you. We also considered the cost of each drill set in order to find options that are suitable for every budget without sacrificing any major features.

Drill power

There are many ways to determine a drill’s power, but the one we’re going with is its maximum rotations per minute—shortened to RPM. This is a less abstract unit of measurement than a drill’s power draw, measured in volts. The faster a drill can spin, the faster you can get your job done.

Weight

Many of the drills in this guide are cordless, which means weight is a critical factor in determining the right one for you. Most of our recommendations weigh less than 10 pounds, which is pretty light for a power tool. You may still feel some strain after holding it for an extended period of time, but you can alleviate that issue by holding the drill with two hands. This won’t be possible with every job, but using both of your hands has the added benefit of allowing you to hold it more steadily.

Accessories

You should only get a drill set that comes with the accessories you feel you’ll actually need for the jobs you’re doing. All of the drill sets we’re recommending come bundled with multiple bits—aka the little pieces you stick into the drill to actually use it. The most common bits terminate in a Phillips or flat head in different sizes, which are used to insert or dislodge screws. Circular bits can be used to create holes straight through different materials, which can be useful on their own, or to create a hole for your screw to go into. Most of our recommendations come with an additional battery, charger, and carrying case.

FAQs

Q: Does a bigger drill battery mean more power?

No, a drill’s battery does not necessarily correspond with its power. A larger battery will allow you to use the drill for a longer period of time, though it’ll add more weight and bulk, which could make it more difficult to use for an extended period of time.

Q: How do I choose a drill?

Begin by deciding whether or not you’d like a corded or cordless model—the latter offers more flexibility, but requires you to keep a battery charged for it to work. Then decide which accessories in the drill set are most important to you—drivers designed to be used on different materials, an extra battery, or a carrying case are among the most common. Finally, consider the cost of your drill set (this should be commensurate with how often you plan on using it) and find one within your budget.

Q: What drill lasts the longest?

All of the drills we’re recommending should last several years if they’re properly maintained. Using the correct driver for the materials you’re drilling through, cleaning the drill and drivers after every use, and properly storing your drill set between uses are all very important to extending the life of your drill as long as possible.

Q: How much does a drill set cost?

This depends on which accessories are included in the kit. You can spend as little as 60 and as much as 300 depending on your needs.

Final thoughts on choosing the best drill set for you

Upgrading from using a screwdriver to a drill set will be revelatory in terms of increased efficiency. Instead of hand cramps, you’ll get quick results. Seemingly annoying DIY tasks, like making a hole in the top of your desk to thread cables through or switching out the handles of your cabinets, will only take a few minutes. We made it a point to prioritize drill sets with a cordless tool, so you can use them anywhere in your home, or take them with you if you’re working on a project elsewhere. A drill set belongs in every home, whether you own a house or rent an apartment, for those “just in case” moments. If you’re already a handy person, picking one up is essential.

Are DeWALT 20v Batteries Interchangeable With Black And Decker? – Explained

If you’re wondering whether DeWALT 20v batteries are interchangeable with Black and Decker, the answer is yes and no. While they may look similar and have the same voltage, some key differences prevent them from being fully interchangeable.

One of the main differences is in the battery connectors – DeWALT uses a different connector than Black and Decker. This means their batteries will not fit into each other’s tools without modification.

Additionally, even if you were to modify the connection, there may still be compatibility issues due to differences in the battery chemistry and capacity, so it may be tempting to try and save money by using DeWALT batteries in your Black and Decker tools (or vice versa). It’s probably best to stick with the batteries designed specifically for your tools to ensure optimal performance and safety.

The Connectors Are Different

While DeWALT 20v batteries and Black and Decker batteries may seem similar, one important difference is that the connectors are different. This means that despite having the same voltage, DeWALT 20v batteries cannot be used interchangeably with Black and Decker batteries without an adapter.

Attempting to use a DeWALT battery on a Black and Decker tool or vice versa can result in damage to both the battery and the tool. DeWALT 20v batteries and Black and Decker batteries are two popular battery options for power tools.

However, it is important to note that these two brands use different connectors for their batteries. The connectors are the parts of the battery that attach to the tool, allowing it to power up and run. While some may assume that all power tool batteries are universal, this is not the case.

You May Damage The Power Tool

DeWALT 20v batteries are known for their durability and long-lasting charge, making them a favorite among contractors and DIY enthusiasts alike. They use a unique type of connector that is specially designed for DeWALT tools. Black and Decker batteries, on the other hand, use a different type of connector that is only compatible with Black and Decker tools.

The connectors are different so the batteries won’t fit other brands’ power tools. By doing this, you may even damage the power tool. This is another concern of yours while interchanging DeWALT 20V batteries with Black and Decker.

If you try to use DeWALT batteries in a Black and Decker power tool, most likely, you are going to damage the Black and Decker power tool. And the same thing will probably happen if you want to do vice versa. This is a terrible idea. Why damage a premium DeWALT power tool just to save a small amount of money?

You May Ruin The Battery

This will probably be the most common outcome if you try to interchange DeWALT 20V batteries with Black and Decker. What will happen if you try to use DeWALT 20V batteries on your Black and Decker tools?

There are no electronics in a DeWALT battery because the necessary electronics are present in the DeWALT power tools. What will be the outcome then? Putting the DeWALT battery in a Black and Decker power tool is the worst outcome. The battery will get damaged. Hence, we don’t recommend doing it at all.

You May Endanger Your Safety

While it may be tempting to use DeWALT 20v batteries interchangeably with Black and Decker tools, doing so can actually endanger your safety. While these batteries may look similar. They are not interchangeable, and attempting to use them with the wrong tool can result in damage to the battery or even cause it to explode.

Additionally, using a battery that is not specifically designed for your tool can compromise the performance of both the battery and the tool itself. It’s important always to use the correct battery for your specific tool to ensure optimal performance and safety. Don’t risk damaging your tools or putting yourself at risk – always use the appropriate battery for your Black and Decker tools.

The Business Policy

Yes, you heard it right. You can’t interchange DeWALT batteries with Black and Decker for this reason. If you could do that, would you go for a DeWALT battery for once? The answer is very simple. No.

Users and critics consider DeWALT a very high-quality brand in terms of power tools. You must use the required batteries to power the cordless DeWALT power tools. Selling batteries is one of the best ways to profit from cordless tools. If you can, just go and use a Black and Decker battery in a DeWALT power tool. What is the point of manufacturing DeWALT batteries, then?

Exceptions To DeWALT Battery Compatibility Rules

While DeWALT 20v batteries are generally interchangeable with Black and Decker tools, this compatibility has some exceptions. For example, certain older models of Black and Decker tools may not be compatible with DeWALT batteries or may require an adapter to work properly.

Additionally, some newer models of DeWALT batteries may not be compatible with older Black and Decker tools. It is important to check the compatibility of your specific tool and battery before attempting to use them together.

Yes, there are a few exceptions to the DeWALT battery compatibility rules. The following batteries can be used with the DeWALT tool brands with some minor adjustments:

18V Li-Ion Batteries

These can be used in all DeWALT tools that use 18V Li-Ion batteries, including the cordless drill/driver, hand saws and trimmers Porter Cable impact drivers. First, use these batteries in the tools to ensure the voltages are compatible. The voltage on a Li-Ion battery ranges from 3.6 to 11.1 volts, so be sure to check the voltage of the battery before using it in a tool.

20V Max Lithium Lon Batteries

These can also be used in all DeWALT tools with 20V Max batteries, including saws and drills/drivers with more power. First, to use these batteries in the tools, ensure they are labeled 20V Max and have built-in protection features (like over-discharge warnings) to prevent them from being used in other devices.

12V Max NiCd Batteries

These also work relatively well with some DeWALT tools that use 12V Max NiCd batteries. But they may not be compatible with all of them. To use these batteries in a tool, first, make sure about the label of 12V Max NiCd and has built-in protection features. It helps to prevent them from using in other devices.

Which Batteries Are Compatible With DeWALT 20V?

Now coming to our next question, is there any battery that is compatible with DeWALT 20V? It may surprise you to hear this, yes. There is one. In 2016, DeWALT released the Flexvolt platform. What is the Flexvot platform, anyway?

See the name ‘Flexvolt’ carefully. If we divide the word, we will get two words- ‘flex’ and ‘volt.’ We can conclude that this name means flexible voltage. You can use the Flexvolt battery on various power tools. If it is necessary, the battery can go down to cope with lower voltages.

For example, you have a powerful tool that requires a 20V battery. And you have a 60V Flexvolt battery. In this case, the Flexvolt battery will go down to work as a 20V battery to run the power tool. Sounds amazing, right?

Apart from the Flexvolt batteries, we haven’t found any other batteries that are compatible with DeWALT batteries. Well, if you have Flexvolt in hand, is it even necessary to find more alternatives?

How To Find The Right DeWALT Battery?

You should keep a few things in mind when looking for the right DeWALT battery. These include the battery’s voltage, amp hour rating, type of construction, and the tool’s intended use. Voltage – The battery’s voltage is important because it dictates how much power the battery can deliver. The higher the voltage, the more power the battery can provide.

The amp hour rating is important because it tells you how many hours the battery can last before you need to replace it. Generally speaking, higher amp-hour ratings mean longer-lasting batteries.

Type of construction – Batteries are typically either lead-acid or lithium-ion batteries. Lead-acid batteries are heavier and require more space than lithium-ion batteries. But they are more reliable and last longer than lithium-ion batteries.

Intended use – If you’re unsure which type of battery your tool requires. Please consult your tool’s documentation or contact DeWALT customer service for assistance.

What To Do In Emergencies?

In emergency situations, you may not have access to a DeWALT 20V battery. It is important to know if Black and Decker’s batteries are interchangeable. While the two brands use similar battery designs, they are not always compatible with each other. Attempting to use a Black and Decker battery in a DeWALT tool or vice versa can result in damage to both the tool and the battery.

However, there are some third-party adapters available that claim to make the batteries interchangeable. We recommend exercising caution when using these adapters as they may not be reliable or safe. In emergencies, it may be best to try and find a compatible battery from a hardware store or borrow one from someone with the same brand of tools.

Use A Dremmel In Order To Cut Notches

If you’re wondering whether DeWALT 20v batteries are interchangeable with Black and Decker, the answer is yes! However, there is a catch. In order to make the batteries fit properly. You may need to use a Dremel tool to cut notches into the battery compartment of your Black and Decker tools. This may seem daunting, but it can be done easily with the right tools and a steady hand.

Once the notches are cut, your DeWALT 20v batteries should fit snugly into your Black and Decker tools. Giving them new life and increasing their usefulness. So don’t throw away those old batteries just yet – with a little bit of DIY know-how, you can give them a second chance at powering your favorite tools.

Use Adapters

If you’re wondering if DeWALT 20v batteries are interchangeable with Black and Decker tools, the answer is not straightforward. While they may look similar, DeWALT and Black and Decker batteries have different connectors and voltages. Which means they are not directly compatible.

However, with the use of adapters, you can make them work together. Adapters can be purchased from third-party manufacturers or made at home with some basic tools. It’s important to note that using adapters may affect the performance of your tools and may void any warranty.

So it’s always best to consult the user manual or contact the manufacturer before attempting to use an adapter. With a little bit of research and caution, you can extend the life of your tools by utilizing DeWALT 20v batteries with Black and Decker tools through the use of adapters power tools.

Conclusion

Handy outdoor power tools make quick work of tackling overgrown weeds and grass, giving the yard a tidy look and trimming hedges and shrubs. We put battery-powered trimmers through their paces on several grass or weed types to see how well they ran and cut, ultimately arriving at this list of the best battery trimmers.

For ensuring a polished look to a lawn, the best string trimmer is a great investment. These yard-care tools spin a cutting head loaded with nylon string (instead of a fixed blade) to cleanly trim the grass at the edge of a lawn or mow down weedy areas. Though gas and electric models once dominated, new and improved battery-powered versions don’t require mixing fuel or storing gasoline like gas string trimmers do, nor are they limited by the length of an extension cord, like corded electric string trimmers are.

Some battery trimmers are better suited to different-size yards, users, and budgets. So we could help consumers make the right choice, we tested some of the most popular string trimmers to find out how they perform under real-world conditions. To qualify as a top pick, a string trimmer should be durable, powerful, and easy to operate. The string line should exit the reel easily with no need for the user to constantly remove the reel cover and untangle the line.

The following battery-powered string trimmers are at the top of their class. Anyone looking to invest in a trimmer is likely to find one here to fit their landscaping needs.

How We Tested the Best Battery Trimmers

To truly test these battery-powered string trimmers, we started by assembling the tools and charging the batteries. Most trimmers arrived with the batteries about 25 percent charged right out of the box, but a full charge allowed us to gauge runtime at full power. Although some of the trimmers offer lower power settings that could extend runtime, we found that the lower settings simply made them less capable when it came to coarse weeds, so we ran them at full power for testing.

We put each trimmer through its paces in a variety of real-world scenarios: “clean” lawn grass, weedy grass, and natural areas featuring coarse, weedy seedlings and vines. To earn a spot in our lineup, the lightweight 20-volt (V) trimmers had to deliver a clean, crisp cut in both clean and weedy grass sections. In addition to trimming the grass zones, we used the 36V, 56V, and 80V models to cut through woody, viny growth in natural areas. Along with cutting power, we tested for battery runtime, maneuverability, and operator comfort and determined the best battery trimmer by category.

Our Top Picks

These reviews describe the key features of each cordless string trimmer and how the models performed in our backyard tests.

STIHL FSA 60 R 36V Battery Trimmer

It makes sense that the STIHL FSA 60 R would be a top performer in this test group. It comes from a brand with a long history of industry-leading outdoor power equipment. This string trimmer measures just over 66 inches long, weighs less than 10 pounds with the battery installed, and works for about 25 minutes per charge. The 36V 3.9 amp hours (Ah) battery charges in a little more than 2 hours.

The tough polymer material used for the motor housing and debris shield help keep the weight down. A few other standout features include a variable-speed throttle trigger, trigger interlock, battery retainer latch, EasySpool cutting head, bump guard, and hang loop. The trigger interlock and battery retainer latch prevent accidental startup. The variable trigger and EasySpool head improve operating efficiency by saving battery life and minimizing the time it takes to reload, respectively. The bump guard protects sensitive surfaces during close trimming, and the hang loop offers a convenient way to store the tool when not in use.

This is a great all-around pick for quarter- to a half-acre yards. The relatively short runtime of the STIHL FSA 60 R belies a very capable trimmer. In our tests it easily and cleanly sliced through all kinds of grass and weeds, including tough tree saplings up to about ¼ inch thick. The shorter runtime actually mattered less because the trimmer cut so well, and we moved at a faster pace than with some of the other trimmers with longer runtimes.

The other thing we noted here was the amazing level of operating comfort. The trimmer was fairly lightweight to begin with, but the weight was so well balanced—with just enough weight forward of the front handle to keep the head near ground level—that using it required significantly less effort than what was required of some of the other trimmers that weighed about the same. Also, vibration was minimal, so after trimming we had plenty of energy to keep working.

Product Specs

  • Weighs less than 10 pounds but easily powers through tough weeds
  • 25-minute runtime per charge for about 5,000 linear feet of trimming
  • Excellent balance to keep the head at ground level
  • EasySpool head, bump guard, variable-speed throttle, and accidental start protection
  • Smallish 13.8-inch cutting swath is on the small side for open spaces
  • 2-hour recharge time for battery is longer than that of some competitors

Ego ST1511T Power 15-Inch Powerload String Trimmer

Ego Power has made a name for itself in the outdoor power-equipment category by building an affordable battery-powered tool line that competes favorably against old-fashioned 2-cycle gas-powered equipment. The ST1511T 15-inch string trimmer proved to be powerful, clean, and quiet in testing. The 56V 2.5Ah lithium-ion battery delivers up to 45 minutes of runtime, with a recharging time of just 50 minutes. The bump-feed trimmer head comes preloaded with 0.095-inch trimmer line for more cutting force and less noise. Taller users will appreciate the straight shaft design, and the unit weighs in at just over 10 pounds.

In our tests, the Ego trimmer showed ample power to cut through everything in its path, including overgrown, weedy grass; privet seedlings; and honeysuckle vines. Its well-balanced design, with the heavy battery in back offset by the long, straight shaft, made it comfortable to work with and more agile than others we tested. Our only caveat: For seasonal yard cleanup or maintaining larger landscapes, the 45-minute maximum runtime may not be quite enough.

Product Specs

  • Auto-loading trimmer head reduces downtime while working
  • Adjustable telescoping straight shaft provides a custom fit for different users
  • Excellent power and runtime value at a moderate price point
  • Heavier than some with less forward weight to keep head down
  • Battery is bulkier than others, making the tool tiring to use over an extended period

Get the Ego Power battery trimmer at Amazon, Ace Hardware, or Lowe’s.

BlackDecker LST300 LBXR2020-OPE 20V String Trimmer

To give the yard a polished look without breaking the bank, consider the BlackDecker cordless string trimmer. It features a 12-inch cutting swath to cut down the corners and clean up the edges of small- to medium-size yards. An automatic feed spool means no more stopping to bump the tool when new string is needed. Two 20V lithium-ion batteries are included.

In our tests, this trimmer performed very well in weed-free grass and in weedy lawn areas. With a light weight of just 5.7 pounds, this trimmer is easy to handle without causing arm and shoulder fatigue. The short, straight shaft design is most comfortable for users under 5 feet 9 inches tall. We also liked that with a quick adjustment to the head, the trimmer becomes an edger to neaten up the grass along sidewalks and driveways. In all, we found this affordable tool a solid pick for small obstacle-free landscapes.

Product Specs

  • Pack includes 2 batteries for more runtime, less downtime
  • Automatic feed spool
  • Money- and space-saving design that both trims and edges
  • Battery recharges in just 45 minutes
  • Best for grass only; struggles with coarse, woody weeds
  • Wide debris guard doesn’t fit well into tight spaces

Get the BlackDecker battery string trimmer at Amazon (with extra battery) or The Home Depot.

Makita XRU15PT1 36V LXT Brushless String Trimmer Kit

The Makita XRU15PT1 string trimmer is a premium option to keep the lawn and garden under control. It can handle large yards with enough power to tackle dense weed growth. This cordless string trimmer comes with four 18V 5.0Ah batteries so you’ll never run out of power. Shoppers can purchase this model as a kit that includes a dual battery charger and two sets of batteries, or as a “tool only” for those who already have items from the Makita 18V tool platform.

With a long, straight shaft and high-power cutting head, this 10.4-pound trimmer feels like a pro-quality tool. It was well balanced and articulate while trimming around shrubs and between obstacles. It had plenty of power to cut through tough vegetation. In our tests, it made nice clean cuts and crisp edges in the grassy areas and tore through weedy privet seedlings and honeysuckle vines without hesitation. It’s an excellent candidate to replace gas equipment for medium to large landscapes, though the price may be high for budget-minded shoppers.

Product Specs

  • Runtime is longer than charge time for ready-to-go fresh batteries
  • Includes a second set of batteries for extended work
  • Gas-like power and performance for tough trimming jobs
  • Expensive trimmer due to the high cost of batteries
  • Small debris guard allows some material close to operator
  • Stiff bump head required a hard strike to let out line

DeWALT DCST972X1 60V MAX 17-Inch String Trimmer Kit

When an established leader in pro-grade cordless hand tools enters the lawn-care category, shoppers will want to take note. The DeWALT 60V battery trimmer packs a heavy-duty brushless motor powered by a 60V 3Ah FlexVolt lithium battery that lets it tear through all kinds of tough weeds for at least 40 minutes per charge.

This attachment-capable trimmer comes equipped with a straight shaft and Rapid- loading adjustable spool. It uses.080-inch trimmer line to cut either a 15-inch or 17-inch swath. A safety switch in the grip prevents accidental starts. Users can select high or low power, depending on the project, and control the trimming RPM with a variable-speed trigger. The universal attachment feature lets owners replace the trimmer attachment with a variety of other tool heads, including an edger, hedge trimmer, pole saw, and more.

The DeWALT battery trimmer was one of the heaviest we tested, but also the most powerful. With the standard.080-inch trimmer line that came pre-spooled, this tool had no trouble cutting anything from grass to thin tree seedlings and even tough blackberry canes. In low-power mode it offered more cutting force than the high- power setting of most others we tested. In high range it beat all but the STIHL, which was about an even match in terms of pure power. To be honest, high power was too much for many of our applications, so we also tested thoroughly in low range. It ran about 40 minutes on high, and about 60 on low.

Other than the heavy weight, the only negative point we have to offer is the noise. The trimmer is loud to begin with, and when initially triggering or feathering the trigger it makes an even louder whine/whistle sound. Still, it’s a very impressive tool at a fair price for the power and runtime and a good choice for large properties or cleaning up overgrown areas.

Product Specs

  • Battery type: 60V 3Ah FlexVolt lithium ion
  • Runtime: 40 minutes
  • Weight: 12.95 pounds
  • Outstanding power for clearing overgrown weeds and brush
  • Works with.080-inch or.095-inch trimmer line for normal or heavy trimming
  • Excellent runtime of up to an hour for average grass trimming
  • Power head can run other landscaping tool attachments
  • Heavy weight of just under 13 pounds, but no shoulder strap
  • Longer battery charge time at 135 minutes
  • Noisy operation, especially when initially triggering

BlackDecker LSTE525 20V MAX String Trimmer/Edger

Weighing just 8.8 pounds, this string trimmer is easy to carry, maneuver, and control with an adjustable handle and a safety trigger switch to prevent accidental starts. The 12-inch trimming radius is suitable for keeping the lawn properly maintained without damaging fencing, decks, trees, or other common yard obstacles.

This cordless string trimmer operates with a 20V battery that can last for up to 20 minutes, and a spare battery is included. For edging, simply turn the head and use the built-in wheel to balance as the trimmer string handles the task.

When we used the tool to trim weedy lawn grass patches and edge the curb and driveway, it made nice clean cuts and tracked well to make good straight edges. The shaft and handle adjusted to comfortably fit our 6-foot user. The tool is amazingly lightweight for the amount of power it offers, but the weight is mostly balanced to the front of the handle, and having to manually counterbalance it while working fatigued our tester. Though not built for heavily weed-infested yards, it has ample power and runtime to clean up curb lines, driveway edges, and otherwise maintain a smaller landscape.

Product Specs

  • Very lightweight and easy to carry
  • Handle is customizable to fit the size of user
  • Trimmer doubles as an edger with a simple turn of the head
  • Battery provides limited runtime, although a spare is included
  • Not enough power to tackle coarse, woody weeds
  • Weighted toward the front, which may cause user fatigue

Echo DSRM-2100 eFORCE 56V 16-Inch Battery Trimmer

A wide cutting swath, extended runtime, and powerful trimming ability make the Echo DSRM-2100 eFORCE battery trimmer an excellent choice for large yards. The straight-shaft trimmer is powered by a brushless motor and 56V 2.5Ah lithium battery for up to 56 minutes of powerful performance that rivals traditional 2-cycle trimmers. It cuts a 16-inch-wide swath to get the job done efficiently.

This battery trimmer weighs in at a comfortable 9.75 pounds, making it a relatively lightweight choice at this level of capability. It features battery-saving low/high power settings for different cutting conditions, a variable-speed trigger, and a cushioned handle grip for comfort. The Speed-Feed cutting head comes preloaded with.095 trimmer line and reloads quickly without disassembly.

The Echo eForce battery trimmer is an excellent value for large-property maintenance. In our tests, the cutting power seemed to be slightly less than that of the DeWALT and STIHL trimmers, but it was still very capable. In high-power mode we trimmed for about 40 minutes. But the better-than-average power and wider swath meant that in 40 minutes with the Echo, we were able to complete work that other trimmers would need an hour to accomplish. The noise level was good, and reloading was fast and easy.

This trimmer could have scored higher with improved balance. Although it is a lightweight trimmer overall, most of the weight is in the working end. The heavy cutting head forces the operator to compensate by lifting upward on the front handle and pushing downward on the rear handle while working. We tested with the 2.5Ah battery that comes standard. Working with the available 5Ah battery (sold separately) would rebalance the trimmer to some degree while doubling runtime and increasing overall weight.

Product Specs

  • Excellent price for this combination of power and runtime
  • Wide cutting swath and power performance for large properties
  • Rapid charging system charges the battery in less than 40 minutes

Get the Echo battery trimmer at The Home Depot or Acme Tools.

Worx WG163 20V Power Share GT 3.0 String Trimmer

Owners of small yards may find this lightweight string trimmer an excellent option. It weighs just 5.5 pounds and easily converts from a trimmer to an edging tool; a built-in wheel helps balance the tool while edging. A push-button feed system gives the ability to extend the trimmer string without bumping the 12-inch trimmer head or manually pulling additional string from the trimmer. It comes with two 20V batteries and a charger, and the battery lasts for up to 20 minutes on a full charge.

This Worx string trimmer tackled our grassy areas with ease, both the weedy and weed-free zones, but it wasn’t as capable on rough areas. We were particularly impressed by the edger function, which we found comfortable and well balanced thanks to the 90-degree shaft-rotation capability. The adjustable trimmer head and upper handle let us customize the working angle, but the process of doing so proved clunky. We had to reach down and turn a rather stiff knob at the connection point between the shaft and cutting head to unlock and relock the angle for each adjustment.

Product Specs

  • Trimmer and edger in a single tool
  • Smooth push-button Command Feed spool system
  • Adjustable head tilts to 90 degrees
  • Battery provides limited runtime, although a second battery is included
  • Head-tilt adjustment is somewhat awkward and clunky
  • Relatively long 60-minute charging time for 20 minutes of runtime

Husqvarna 320iL 40V Battery String Trimmer

One limiting factor of most string trimmers is the cutting head’s direction of rotation; it matters more than one might think. The direction of rotation determines where the clippings will go, and in some situations, how the user should grip the trimmer. The Husqvarna 320iL 40V battery trimmer offers a solution, thanks to its dual-direction cutting head. At the touch of a button, we could change from clockwise to counterclockwise rotation and back, without changing grip on the handles.

This straight-shaft trimmer is powered by an efficient brushless motor and 40V 4Ah battery that drives about 45 minutes of runtime per charge. It features a Rapid-load cutting head that comes prespooled with.080 trimmer line and cuts a 16-inch swath. Low-vibration technology improves operator comfort, and the machine weighs in at just over 10 pounds with the battery.

The Husqvarna 320iL ranked near the top of the test group in terms of user comfort and quiet operation, but its power was somewhat underwhelming after the big showing from the STIHL and DeWALT trimmers. We were super impressed with the dual-direction feature. It allowed us to use the trimmer right- or left-handed, and we could safely trim curb lines from either direction without standing in the street. On high-power mode the trimmer performed lawn-trimming duty superbly, but in heavy weeds and natural areas it could not keep up with the more powerful trimmers.

Anyone not interested in going off the beaten path might still do well to consider this trimmer. Its balance is impeccable, rivaling the STIHL in comfort even though it’s a fraction of a pound heavier. And for quiet operation, this one takes the gold medal. The only real question regarding comfort and control was, why so many buttons? Its four thumb-operated buttons control on/off, high/low power, clockwise rotation, and counterclockwise rotation.

Product Specs

  • Dual-direction trimmer head leaves clippings where desired
  • Excellent balance for comfortable extended use and less fatigue
  • Among the quietest of the trimmers we tested
  • The 4 buttons and a trigger seem like too many controls
  • Even the high power is not adequate for heavy-duty trimming

Worx WG170 20V Power Share Revolution String Trimmer

While plenty of string trimmers also function as edgers, we found this model to have the best dual-function design. At the push of a button, the trimming head on the Worx WG170 Revolution trimmer converts to an edger that rolls easily along the edge of a sidewalk or driveway. The head tilts up to 90 degrees, so it is easy to reach weeds on slopes while standing comfortably.

The trimmer comes with two batteries plus a charger and three extra spools of trimmer line. The string trimmer also boasts a handy spacer guard that keeps it from bumping into plants, and the shaft adjusts to suit taller or shorter users. It cuts a 12-inch swath and operates on a 20V lithium-ion battery. We tested the tool with the 2Ah battery, but it also comes with a 4Ah battery at some retailers.

In our yard, this trimmer cut through and created a crisp edge on both weedless and weedy lawn areas. We really liked the easy adjustable feature on the trimmer head: A twist lock holds it in just the right position, up to 90 degrees, for a customized working angle for users of different heights. Also, the batteries are interchangeable with those of many other Worx 20V cordless tools.

Product Specs

  • Adjustable upper handle to accommodate users of different sizes
  • Trimmer head converts to an edger for use along sidewalks or driveways
  • Comes with 2 batteries to make up for shorter runtime
  • Requires a relatively long charging time
  • Trimmer feels underpowered for tackling coarse, heavy weeds
  • Only 20 minutes of runtime per charge

Greenworks Pro 80V 16-Inch Cordless String Trimmer

The Greenworks Pro 80V trimmer is a quality tool that adapts to a variety of other functions with attachments such as a brush cutter. (However, attachments are sold separately.) The 2Ah battery provides up to 45 minutes of runtime and recharges in just 30 minutes. The brushless electric motor is efficient and quiet, providing plenty of torque to cut through heavy weeds without the noise and smell of a gas-powered unit.

In our test areas, the Greenworks Pro trimmer was powerful enough to cut through the toughest weeds and vines with ease. The heavy battery weighs the machine down toward the rear, but the included adjustable shoulder strap makes operation more comfortable. The battery is compatible with other Greenworks 80V tools. Just don’t get too excited about the variable-speed trigger: Although it’s intended to allow a gradual increase from “off” to “high” speed, we found the range of movement between the two to be minuscule; in effect, the trimmer is either “off” or “on.”

Product Specs

  • Battery type: 80V 2Ah lithium ion
  • Runtime: 45 minutes
  • Weight: 10.6 pounds without battery
  • Trimmer has a quiet, efficient brushless motor
  • The recharging time is only 30 minutes; runtime is 45 minutes
  • Gas-like power and performance without the noise and smell
  • Slight lag time between triggering and full power
  • The trimmer’s adjustable speed feature is difficult to use
  • Weight is balanced toward the rear, but shoulder strap helps

What to Consider When Choosing a Battery Trimmer

When shopping for string trimmers, also known as weed eaters, keep in mind yard size, how often the tool will be used, and the height and strength of the primary user. The following key considerations will help in selection.

Trim Width

Trim width, also called swath width, indicates how wide a path the trimmer will cut through weeds in a single pass. Many models on the market today feature swath widths of 10 to 18 inches. The wider the width, the more power the trimmer must have, which often means the tool will be heavier because it will require a larger, more powerful battery.

Battery Type

Running a string trimmer requires a hefty dose of power. Though most of today’s trimmers run on rechargeable lithium-ion (Li-ion) batteries, a few accept nickel cadmium (NiCad) batteries. Li-ion batteries are more powerful, but NiCad batteries are less expensive (an average of 70 to 125 less). Li-ion batteries also are smaller, hold a charge longer, and provide full power throughout the discharge cycle.

NiCad batteries suffer from “memory effect,” meaning if the battery is used before it has fully charged—or if it’s recharged before its power depletes—it will “remember” the earlier charge level and won’t hold a longer charge in the future. If choosing a trimmer that has a NiCad battery, let it charge fully before use and drain completely before charging. For most users, a string trimmer with a Li-ion battery will be the best choice.

Voltage

Along with battery type, consider how much operating power the battery has, which is measured in volts. Today’s rechargeable string trimmer batteries average from 18 volts up to an average of 60 volts of power. powerful batteries at the high end often are intended for commercial use and can cost 200 or more per battery.

Some string trimmers in this category sell without a battery (or battery charger), which the user must purchase separately. This could be a cost-saving benefit for those who are adding to a same-brand, battery-compatible cordless tool collection, since the same battery will power multiple tools. However, it can be more convenient to purchase a kit with multiple batteries to have one on the charger while the other is in use.

Feed Type

The “feed” of a string trimmer indicates how the trimmer head releases additional trimmer line as it becomes frayed and broken during use. The standby is a bump feed where the user bumps the bottom of the trimmer (the area where the spool attaches) on the ground to release a few inches of fresh line.

Some newer models feature an auto-feed sensor that gauges the length of the strings and releases more when needed. Still others have a push button to release more line. Auto and button feeds eliminate the need to bump the spool, which can reduce the risk of damage if bumped too hard, but many commercial-type trimmers still use bump feed because it’s quick and easy.

Curved vs. Straight Shaft

Some string trimmers feature a straight shaft that runs from the handle to the cutting head, while other models feature a distinct curve in the lower shaft about two-thirds of the way down. Some users find curved-shaft trimmers to be easier to operate since the spool end already rests at a handy angle for weed whacking.

Straight-shaft trimmers often accommodate interchangeable tools, such as a tree trimmer head, which can be swapped out depending on the task at hand. In general, straight-shaft trimmers work better for users at least 6 feet tall, while shorter users will appreciate curved-shaft trimmers.

Noise

Battery-powered string trimmers have a distinct advantage over gas-powered trimmers when it comes to noise pollution. Gas-powered trimmers are moderately loud, emitting an average of 90 decibels (about as loud as a motorcycle passing by from 25 feet away). By contrast, a cordless string trimmer emits approximately 77 decibels, which is comparable to casual conversation.

FAQs

Those who are still unsure about how to use a battery string trimmer may find the following answers to common questions about these tools helpful.

dewalt, batteries, interchangeable, black

Q. Can a string trimmer cut weeds?

A string trimmer is used to cut and control weed growth around the home and garden. However, light-duty trimmers may have issues with very dense weed growth.

Q. Can you use a string trimmer to cut grass?

A string trimmer can be used to cut grass, though you need to be careful not to cut the grass too short while trying to keep the trimmer balanced. It isn’t the easiest way to cut the grass, but it is possible.

dewalt, batteries, interchangeable, black

Q. Can you edge with a string trimmer?

Yes, a string trimmer can be used for edging the garden, driveway, walkway, or sidewalk. If you have a large yard, it may be better to invest in a separate edging tool.

Q. How many volts should be in a trimmer?

String trimmer batteries average from 18 volts up to 80 volts. Typically, the higher the voltage, the longer the battery life.

Q. How do you edge a lawn with a string trimmer?

Hold the string trimmer perpendicular to the lawn to keep the cut even. Position the head about 4 inches off the soil so the string has space to rotate. The string should rotate and cut through the grass and dirt. As you move along the desired borders, keep the head balanced and even. Clean up the cut grass and dirt to finish the job.

The Complete Cordless Tools Battery Guide

Ampere hours, voltage, Li-Ion, NiCd… all these are terms that you might hear thrown around when you are looking at purchasing a new cordless tool. But what do they all mean? How do you know when the salesperson has no idea what they are talking about and just wants the commission?

Well, let’s give you a bit of an education and go over the different battery types, ratings and everything else you need to know regarding batteries for cordless tools. That way you can be armed with all the info you need to make an informed decision.

How Battery Technology Has Improved

If you told a carpenter that you relied on nothing but a battery drill to do all your screwing and drilling jobs 15 years ago, they would have laughed at you. These days, cordless drills, nailguns and other such cordless tools are their most used devices.

Battery technology has improved vastly over the past decade, and in some cases, the tools that they power can perform just as well as a corded tool.

One of the main problems with batteries in the past was their ability to last the distance. There is nothing more annoying than having your battery run out of juice halfway through a job.

Modern-day Li-Ion batteries can provide power for extended periods of time, and also recharge quite quickly – making them a worthwhile investment.

Which Battery Type is the Best for Cordless Tools?

The cordless tool industry has grown exponentially since the release of the Li-ion battery, mainly because of the vast improvement over the other older battery types.

Yes, it is true that some of the other battery types listed in this article are outdated, but they do still have their uses and they are still sold with some cordless tools such as cordless lawn mowers, or grass shears.

The super quick answer: If you want the quick answer as to which battery type is best, then you will probably want to go with a Li-ion battery.

Of course, there are many other things to consider, if you want to learn a bit more then please keep reading.

Understanding Battery Capacity Specifications

When you are shopping for a cordless tool, you will notice that you are bombarded with different battery specifications.

The most common specifications that are all over the packaging and marketing materials are:

Well, surely it is easy right ?

Just choose the biggest numbers and you have the best battery?

While this seems like the obvious answer, it does depend on numerous factors… which we will look at.

Let’s quickly explain some of the most commonly used terms when it comes to cordless tool batteries.

Ampere-Hour (Ah)

What does Ah mean? What does it mean when the Ah or a battery is (X). These are some of the most common questions we get. And it actually isn’t that complicated.

Ah, or ampere-hour is the total amount of charge your battery can deliver in one hour. E.g. Under ideal conditions, a cordless lawn mower that continuously draws 2.0 amperes (amps) of current will drain the total charge of a 2.0Ah battery in 1 hour.

So by that logic, a 4.0Ah battery should last for 2 hours in the same electric mower. This is all assuming of course that the mower draws a constant 2.0A and that conditions are ideal for the battery – which never happens in the real world.

There is another thing to consider here, and that is the fact that a 4.0Ah battery is not necessarily going to last twice as long as a 2.0Ah battery will. In some circumstances, it may actually last more than twice as long. It all depends on the type of battery, how it is wired up and the control circuitry in the battery itself.

But you can still use the basic reasoning mentioned here to roughly judge how long a battery might last.

So what does Ah mean on a battery? To put it simply, Ah is a measure of how much charge the battery can provide. A simple analogy would be the size of the fuel tank in a car.

Battery Voltage

The voltage (V) rating of a battery is a measurement of how much power that battery can provide.

To put this in very simple terms, the higher the voltage, the more powerful the battery. Some cordless devices require more power to run, so a cordless drill that is designed to drill through tough timber is going to need more power than a drill that is only designed to do light work.

Yes, higher voltage generally means the tool is more powerful – but it also means more weight in the tool and these higher voltage tools also generally cost a lot more. It all comes down to choosing the right tool for the job, remember that bigger is not always better.

Memory Effect

The memory effect occurs when a battery is constantly partly drained, then charged without being allowed to fully discharge. The name comes from the fact that the battery remembers how much of its charge was drained before being charged and then uses the shorter charge period as its new capacity.

Not all batteries suffer from the memory effect.

Battery Cycle Life

Cycle life is a measurement of how many times a battery can be charged before losing the ability to retain energy.

For example, Li-Ion batteries in cordless tools generally have a cycle life of 300-500. So theoretically you could charge a Li-Ion battery at least 300 times before it would need to be replaced.

Self-discharge

After a cordless tool battery has been charged, if the battery is not used immediately it starts to slowly lose its charge. Some battery technologies have a much faster self-discharge rate than others.

Keep in mind that a faster self-discharge rate is not always bad – if your tools are never stored away for long periods between use then you probably won’t care about the self-discharge rate at all.

Self-discharge is measured in percentage of charge lost per month.

Deep-discharge

A deep discharge is allowing the battery to completely drain of energy through use. This can be problematic for some battery types (not all) and can severely reduce the batteries cycle life and capacity.

On the flip side, there are some battery types that should periodically be allowed to deep discharge in order to maintain a healthy battery.

Cordless Tools Battery Types

Most guides that you read about cordless tools batteries will be focused mainly on Lithium Ion (Li-Ion) and that is with good reason. Li-Ion have become the go-to battery of choice for most cordless tool manufacturers. This is for a few reasons:

  • They provide a lot of power from a small battery (high energy density)
  • They can be recharged many times (high cycle life)
  • High capacity (Ah/Specific energy)
  • No memory effect

Before we go into too much detail, let’s take a quick visual look at the difference between the 4 main battery types.

We often get asked which batteries are better or which type is better.

Well, we have tried to make it simple to compare the different battery types with this handy image below.

Ok, that’s great – it looks pretty hey?

Maybe – but it does give us a few important insights into the battery types. From this info, we can take the following away:

  • For high current applications (digital cameras, high power torches etc.) NiMH is clearly the best choice. This is because NiMH batteries are capable of delivering a high burst of power when needed (the specific power number is huge).
  • But… The amount of power NiMH can actually store is lower than a Li-Ion battery.
  • Lead Acid and NiCd batteries are pretty much obsolete these days.

So the long and the short of it is: A Li-Ion battery is smaller and can provide a lower current for a much longer period than a NiMH battery. But a NiMH battery can deliver high bursts of current when needed.

Now we will dive a bit deeper into each battery type.

Nickle Cadmium (NiCd) Batteries

The Nickel Cadmium battery has a long history, in fact, it was first invented in 1899! Of course, it only started being mass produced in 1946 and it grew in popularity from there. They are generally outperformed by both NiMH and Li-Ion batteries but are still useful for some jobs today.

NiCd Batteries at a Glance

Cycle life: 1,000 chargesSelf-discharge: 10%Ah rating: 1.2Ah – 2.2Ah (low)

NiCd Batteries Pros

  • Very cost effective
  • Robust and not easily damaged
  • Long life cycle – around 1,000 charges
  • High current flow

NiCd Battery Cons

  • Heavy compared to Li-Ion and NiMH
  • Low capacity (Ah)
  • Must be cool before being recharged
  • Regular deep discharge required
  • Very toxic and not environmentally friendly (contains cadmium)
  • Susceptible to memory effect

Nickle Metal Hydride (NiMH) Batteries

Brought into mass production in 1989, NiMH batteries are a much newer technology. They are an improvement on NiCd batteries in many ways, the main points being that they are less toxic to our environment when disposed of, and have significantly improved capacity (Ah). They do of course come with some downfalls which can be seen in the following sections.

NiMH Batteries at a Glance

Cycle life: loses capacity after around 600 cycles, although this can be improved upon if charged and stored correctlySelf-discharge: 13.9–70.6% at room temperatureAh rating: 2.2Ah – 3.0Ah (medium)

NiMH Batteries Pros

  • Capacity is higher than NiCd batteries
  • Costs less than Li-ion batteries
  • Cycle life can be greatly increased by storing and charging the batteries correctly
  • Safe for the environment
  • Can deliver large amounts of current to high powered devices (cameras, torches etc)

NiMH Batteries Cons

  • Sensitive to temperature and should only be stored and used when between 33 degrees F – 103 degrees F
  • Requires a deep discharge semi-regularly (every 2-3 months), but allowing NiMH batteries to continuously deep discharge will reduce the lifespan and reduce storage capacity
  • Lack of use over long periods of time can be detrimental to the batteries lifespan and capacity
  • When in use you should not let a NiMH battery fall below 70% capacity except when doing your maintenance deep discharge
  • Cost more than Ni-Cd batteries
  • Is susceptible to memory effect but can be reduced with proper charging. Memory effect is also reversible to a degree by carrying out a few proper charge/discharge cycles

Reconditioning NiMH Batteries

If your NiMH batteries have developed a memory effect or capacity has been reduced, then it is likely you can recondition them by following this guide.

Lithium-Ion Batteries (Li-Ion)

Entering commercial production in 1991, the newest technology in batteries for cordless tools is the Lithium-Ion battery (Li-Ion). As far as we are concerned, Li-Ion batteries are the best choice for cordless tools, whether it is a cordless lawn mower or a cordless drill.

Li-Ion batteries do not suffer from a memory effect and they are not affected by poor charging habits. Li-Ion batteries instead wear out over time due to age and use. The main downfall of this type of battery is the relatively short life cycle (

Li-Ion Batteries Pros

  • Very light-weight and small
  • Hold a large amount of energy
  • Self-discharge rate is very low at normal room temperatures
  • No memory effect
  • Very high capacity
  • Requires no maintenance

Li-Ion Batteries Cons

  • High temperatures during use or charging can cause the batteries to explode, although most feature adequate safety features to prevent this
  • High cost compared to other battery types
  • Is sensitive to heat and impact

Lead Acid Batteries

Lead-acid batteries are not commonly thought of when it comes to cordless tools, but they are still quite common in cordless lawn mowers so we have decided to give them a small section in this article.

The lead-acid battery was first put to commercial use in train carriages in 1859, it has obviously had multiple revisions and improvements since then but is still widely used today for a number of applications.

You will typically find these used as cordless lawn mower batteries and batteries for the starter motor in ride-on mowers. This is because these tools have much more room for a larger and heavier battery.

Lead Acid Batteries Cons

  • Loses significantly more capacity in cold weather than Li-ion
  • Worse for the environment than Li-ion due to much more mined material being required
  • Lose voltage slowly as they discharge resulting in less power
  • Lose the ability to be recharged if left discharged for too long
  • Very heavy

Charging Cordless Tool Batteries

In the past, you could mix and match different chargers with different rechargeable batteries. These days, most cordless tool batteries are designed to work with a specific charger, especially those with Li-Ion batteries. You will find that Lead Acid batteries can be charged in many different ways, but it is always best to follow the manufacturers instructions and use the charger that the manufacturer provided with the tool.

The Future Of Cordless Tool Batteries

If I could turn on my crystal ball and tell you exactly where battery technology was heading… I would! Unfortunately, my crystal ball is being repaired!

But, I can tell you what I do know and what some of the worlds most renowned battery experts know.

The truth is that at the moment, there is no magical battery technology being developed that will change the world. While there are some theories of technologies that MIGHT work – there really are no working models for the moment.

There is, however, lots of money being spent on improving Li-Ion battery tech. This is due to the rise of electric cars and stationary battery energy storage (for storing energy generated from wind and solar power). So we should see a new generation of Li-Ion batteries being developed that will slowly take over the market as manufacturing ramps up and costs come down.

Cordless Tool Battery FAQ

Q: Can you recondition power tool batteries?

A: Yes you can, there are a few ways to give your batteries new life. Some methods are mentioned in this post. Or you can completely rebuild your battery – although be very careful with this as it can be dangerous.

Q: How long do Li-Ion batteries last?

Li-Ion batteries have a cycle life of up to 1,900 cycles. Generally, the Li-Ion cells will last 2 – 3 years before needing to be replaced.

Q: How Long do Cordless Drill Batteries Last?

It really depends on the type of battery and how you use/store them. But a good rule of thumb is you can expect about 2-3 years out of most cordless drill battery types.
