Should I Buy It?

If you're looking for high-performance, compact batteries for your power tools and don't mind paying a bit extra for quality, these DeWalt batteries are a solid investment. They're especially recommended for heavy-duty tasks that require a lot of power in a short period. However, if you plan to use them for all-day projects regularly, you might want to consider backup options due to their limited runtime.


  • Great for females who want to do a little repair job themselves.
Awesome little battery, works very well, and is not as heavy as the larger ones. Excellent for female use. Keeps a charge while being smaller and easier to use.

  • More power than expected.
Loved these at the sale price. Lasted longer than I had expected for the smaller battery and the lighter weight made it a great value. Big Dewalt fan and this continues my appreciation.

  • Excellent Batteries for DIYers with Dewalt tools
Great Power Delivery for home tools. These batteries are extremely light weight, output consistent power to all my dewalt tools, and constantly deliver on DIY projects around my home. For heavier use, I would probably go with the 3.5 powerstack or the 5Ah. But for light duty or working in weird spaces at awkward angles, the weight savings and small size is a dream. ... show more

  • Ok, but thought the run time would be a bit longer
As a delwalt nut with over a dozen cordless power tools, My array of batteries are pretty vast. The traditional dewalt 20v batteries of this size are obviously limited in the scope of work they can do and these are no different. I was expecting a bit more run time compared to the basic 2ah ones I have however. They certainly do work longer but not to a great deal longer. I'd still buy them again but don't be lead to believe they are night and day better. ... show more

I have used these batteries but they are fully charged.

  • Pay attention to who is selling DeWalt tools!
Lasted two months. I thought I had purchased these two DeWalt 20v batteries from Amazon, turns out they came from a reseller. They lasted two months before dying. I attempted to file a warranty claim with DeWalt, but Industrial Tools is not an authorized retailer. No warranty. Buyer beware.
