Exactly what I needed

This battery was 100% what I needed. It works perfectly with all of my other DeWalt tools, like my angle grinder and work light. I usually am only doing DIY projects or general home maintenance. I chose DeWalt because I knew I'd be getting the power I wanted and the durability I needed for being a homeowner. These batteries and the battery system are a big part of that!

Such Great Batteries

I have two of these batteries and use them on several of my DeWalt tools and have been very impressed with the power and longevity of the battery. I have used them with my impact drill, hand grinding we, and a 3rd party 6” chain saw and I rarely have to stop and charge the batteries before completing a job. I also found converters for my B@D tools and am able to use them with great success. Compared to other makers, the DeWalt batteries are far more superior.
