The best battery charger for power tools starts with the battery brand you already own. For DeWalt 20V owners who want more runtime per charge, the Bslite 20V Max battery with DCB112 charger station is the first pick. It also helps to read Makita GRH10 Battery and Charger Compatibility.
The battery lists a 5000mAh capacity. More capacity means more drilling or cutting before you have to stop and recharge. It is also listed as compatible with all DeWalt 20V MAX tools.
A charger has to match the battery’s brand and voltage, so a DeWalt 20V charger won’t work with a RYOBI or CRAFTSMAN pack. Settle that first, then compare runtime and charge time. The battery’s 4-level LED display (25, 50, 75 and 100 percent) shows how much charge is left. It also helps to read Best Cordless Chainsaw: Compare Options for Yard Work.

Bslite 20V Max Battery and Charger: Best for DeWalt 20V owners who want more runtime
The Bslite 20V Max battery is the first pick for DeWalt 20V owners who want more runtime per charge. It is a 20-volt replacement battery with 5000mAh capacity that fits all DeWalt 20V MAX tools.
The maker says the battery runs 30% longer than standard batteries under continuous 5A discharge. For you, that means fewer stops to swap packs during a long cut session or a full day of drilling.
The maker also says zero memory effect means you can top it up at any time, even at 50% power, without shortening its life. That lets you grab a quick charge between tasks instead of running the pack flat first. The battery’s optimized discharge curve keeps voltage stable until it is empty, so your tool should hold steady power later into the charge.
Pros
Buyers say it works well with DeWalt tools and fits them properly.
Buyers say it is a cost-effective alternative to original batteries.
Cons
It is built only for DeWalt 20V MAX tools, so it is not a fit for other brands.
Buyers report the charging indicator light never comes on.
Buyers report the battery stops working after about ten seconds and does not last long.
If you need quick top-ups on CRAFTSMAN V20 tools, the CRAFTSMAN V20 pick fits better.
CRAFTSMAN V20 4.0Ah Battery and Charger: Best for CRAFTSMAN V20 owners who need quick top-ups
CRAFTSMAN V20 Battery and Charger is the pick for CRAFTSMAN V20 owners who need quick top-ups. The stated charge time and charge indicator are what make it fit that buyer.
The maker says the charger charges compact V20 batteries in 60 minutes or less. A battery that runs down at midday can be ready again before the afternoon starts, so you are not waiting on a second pack to keep the job moving.
The battery has a 3-LED state-of-charge indicator. You can see how full the pack is before you clip it in, instead of guessing. The charger also protects battery cells for long life, which matters if you charge the same pack every day.
Pros
Buyers say the charger recharges quickly, about an hour for the 4Ah battery
Buyers say the battery holds its charge well and lasts a long time
Buyers say the battery and charger are good value for the money
Cons
It works only with CRAFTSMAN V20 batteries, so it will not charge packs from other brands
If you run DeWalt 20V tools, the 20V Max replacement battery with DCB112 charger station is the better fit.
Luxionbatt 12000mAh 2-Pack with Charger: Best for DeWalt 20V users with heavy daily use
This 2-pack set is for DeWalt 20V owners who go through a lot of battery power in a day. The package includes 2 – pack 12.0Ah batteries and a DCB112 charger, so a spare is ready while the other one charges.
The maker lists 12000mAh capacity for the 2-pack, which gives you more runtime before you need to swap. The maker says the charger fully charges a 20V battery in just 90 minutes, about the length of a lunch break, so you can refill during the workday. The charger’s maximum current is 3.0A, which sets how fast it pushes power into the battery.
The charger has an LED indicator that shows charge status, so you can see progress without guessing. Built-in safeguards monitor each battery to protect against overcharging, overloading, overheating, and short-circuiting. The batteries are listed for DeWalt 20V models including DCB200, DCB201, DCB203, DCB204, DCB206, DCB207, and DCB180. The maker offers a 1 year warranty.
Cons
It is a replacement brand, not DeWalt itself.
If your tools are CRAFTSMAN V20, the CRAFTSMAN V20 battery and charger is the better fit.
CRAFTSMAN 20V 2-Pack with Charger: Best for CRAFTSMAN 20V owners who need a spare battery
This is the pick for CRAFTSMAN 20V owners who need a spare battery. The kit gives you two 20-volt batteries and one charger in one box.
The maker lists two CMCB204 4Ah batteries and one CMCB104 charger. In daily use, one battery can charge while the other runs your drill, so a flat battery doesn’t stop the job.
The maker states premium grade high performance cells and a longer cycle, which it says means extended battery life. The charger has a 3-LED state of charge indicator, so you can see how much charge is left before you grab a battery. The maker also states no memory and virtually no self-discharge, so a battery stored between jobs loses its charge more slowly.
Pros
Two batteries and a charger in one set, so a spare is ready.
A 3-LED state of charge indicator on the charger.
Virtually no self-discharge, so stored batteries hold their charge longer.
A 2 Year Limited Warranty on the set.
Cons
At 4.4 pounds, it is heavier than the 3-pound CRAFTSMAN V20 kit and the 1.9-pound Ryobi One+ kit.
The set has one charger for two batteries, so you share that charger between them.
If you own DeWalt 20V tools instead of CRAFTSMAN, the Bslite 20V Max battery with DCB112 charger, the first pick, is the better fit.
Ryobi One+ 18V 2.0Ah Battery and Charger Kit: Best for Ryobi One+ owners who want fast charging
The Ryobi One+ 18V 2.0Ah Battery and Charger Kit is the pick for Ryobi One+ owners who want fast charging. The maker says it charges from 0 to 100 percent in under an hour and works with the RYOBI 18V ONE+ System.
A charge that finishes in under an hour means a dead battery can be back in use during a lunch break instead of sitting on the charger overnight. The maker also says the kit delivers the same output in extreme weather, which matters if you work in a cold garage or a hot yard.
The kit is built for the 225 tools in the RYOBI 18V ONE+ System, so one battery can move between drills, saws and other tools you already own. The maker lists up to 1.5x more runtime, which means fewer stops to charge during a long task.
Pros
Charges from 0 to 100 in under an hour.
Works with 225 tools in the RYOBI 18V ONE+ System.
Buyers say it works well with the drills and saws they already own.
Buyers say it is easy to use and good value for the money.
Cons
Buyers complain the battery runs out after only 10 to 15 minutes of use.
If you own DeWalt 20V tools, look at the first pick, the 20V Max Battery Replacement for Dewalt Battery 5.0Ah with DCB112 Battery Charger Station, instead.
How do you choose the right charger for your tools?
Start with the battery brand and voltage, because a charger only works with the battery system it was built for. A DeWalt charger will not charge a CRAFTSMAN pack, and a 20V pack will not fit an 18V tool. Check the brand and voltage on your tool’s battery slot before you shop.
Next, think about how often you swap batteries. If you run a tool for a short job now and then, a slower charge is fine. If you switch packs several times a day, pick a charger that refills a battery quickly, so the pack you just used is ready when you need it again.
Then decide between one battery with a charger and a 2-pack. A single battery suits a weekend project or an occasional tool. A 2-pack suits longer days, because one pack runs your tool while the other charges, and you lose less time waiting.
Finally, look at the charger’s indicators and safety features. A charge-level light tells you when a battery is full, so you are not guessing. Overload protection cuts charging when something goes wrong, which protects both the battery and the charger. Look for both before you buy.
Where should you start?
Bslite 20V Max battery with DCB112 charger is the first pick for DeWalt 20V owners who want more runtime. If your drills and saws already take DeWalt 20V MAX batteries, start there.
The one thing to remember is to match the battery brand and voltage to your tools before anything else. A charger only works with its own system, so a 20V charger will not power an 18V tool, and a DeWalt battery will not fit a CRAFTSMAN tool. Check the label on the battery your tools already use, then look for the same brand and voltage among the picks.
Your next step is simple: write down the brand and voltage of every cordless tool you own. Pick the kit that matches the largest group of them. If you run one brand at home, that choice is usually the easiest and least expensive way to keep your tools running, because you can share batteries and chargers across them.
