Amazon has been the best place to score deals on tools this summer, whether you're looking for a basic screwdriver or something more complex like a miter saw. The site is also host to tons of discounts on reliable DeWalt power tools, including the shopper-favorite drill and driver kit. Despite that, the best DeWalt sale isn't on any of its tools, but rather on the convenient replacement batteries, including one set that's over $130 off.

Right now, the two-pack of DeWalt's 20V Max XR 5Ah batteries is on sale for just $126—51% off the normal $259 price. This set has been purchased more than 3,000 times in the last month and has earned over 19,000 five-star ratings from shoppers who can confirm that they're "absolutely genuine." They're also available in a 4Ah model for $113, but it's hard to deny the value that's packed into the more powerful 5Ah set.

These lithium-ion batteries are powerful, with an estimated 60% more capacity than DeWalt's standard 20V Max batteries. They're the ones preferred on worksites but are a fine addition to any home DIY-ers tool kit, especially those with big summer projects planned. It weighs about 1.5 pounds, which is on par with other batteries of this size. It has a convenient gauge that displays the remaining battery life—a helpful feature for those working where power isn't readily available. DeWalt also includes a three-year limited warranty on the battery.

Power tool batteries aren't cheap, but those who have made the switch to these say it's well worth the investment. "Best battery out there," one shopper attested. "Hands down, these DeWalt 20V Max batteries are great—for the money, you can't go wrong. I use them daily and they have not let me down. The power level button is a lifesaver; knowing how much charge you have when packing for a day's worth of work or difficult working conditions. This is now the only battery I buy."

Others have learned that using DeWalt batteries for DeWalt tools is a massive upgrade from using less-expensive third-party batteries. "I've only ever used the cheap knock-offs," a shopper explained. "After those started dying on me randomly, I decided to bite the bullet and sell my kidney to give these a shot. I must say, I am impressed by the power and performance of these. They seem to just handle high-draw application orders of magnitude better than the third-party ones. Wish they weren't so damn expensive, but if you need performance and reliability, I don't think they can be topped."

If your tool bench is vibrantly yellow, then it pays to have a few powerful DeWalt replacement batteries like the ones in this set ready to go at a moment's notice. The price of power tools on Amazon tends to fluctuate, so make sure to pick up a set for yourself soon.
