    • Work great! Great quality.
Style: 20V MAX
I'm very happy with these batteries, and I've been using then for probably a year. The size and weight is far less than some of my other DeWalt batteries, but the capacity is every bit as good as it claims to be. When the batteries on my cordless tools needed replacing, I decided to switch the whole kit over to DeWalt. That was because of the high quality of the few DeWalt tools I had, and the fact that I could buy one set of batteries to share across all my cordless tools. It turned out to be a very good decision. The DeWalt tools and batteries perform significantly better than what I had before--and those were quality tools! The batteries fit flawlessly across drills, impact drivers, angle grinders, and vacuums. Yes, the brand sells at a premium price, and yes you get more quality and performance for that price. I use my tools frequently and often for hours at a time. To me, the tools in general and these batteries in particular have proved to be worth it. ... show more

    • Don’t buy knock offs!

So much better than the knock offs! They last longer and they are lighter. Sometime it pays to pay just a little more!

    • Held charge for a long time
Style: 20V MAX
Got these batteries for my electric chainsaw so that we could trim all the trees in our back yard. The batteries worked perfectly and held a charge for a few hours of constant use.
