  • Real DeWalt batteries
Real DeWalt batteries. Work well, slim size. Higher amp hour than what originally came with my Drill/impact driver.

  • Trusted Dewalt
legit batteries, not knock-offs. true Dewalt longevity, and fit. Reliable charging. They weigh a little more than expected, but not too much.

  • I love the 4ah slims.
I love this style for my drills or impact drivers. I read they're being phased out by DeWalt which sucks. I'll probably buy a few more while supplies last. The ones I got have 2025 date stamps so brand spankin new.
