Rated 5 out of 5 by from DeWalt XR batteries Good battery for longer/sustained use. All existing batteries I have purchased are 2.0Ah and are good but drain quite quickly when used with saw, drill’s & multi tool.

Rated 5 out of 5 by from Good battery, lasts a long time. Bought it for my orbital sander as my smaller batteries didn’t last very long. I didn’t want to get anything too large and heavy, that would make using the sander more difficult. This is just the right balance. It lasted a couple of hours of the sander on full blast.

Rated 5 out of 5 by from DeWalt XR 18V Battery 4.0Ah The battery does what it says on the tin, as the saying goes. My husband has used it for his xr drill driver and his xr brushless combi drill and it is great.
