This is the highest Ah DeWalt compatible 20V Max battery that I have and it's really nice to have one that will actually get through the job without running low. Prior to this the biggest battery I had was a 4Ah battery which did a pretty good job but would run out before the job was done quite often. This 9Ah battery has plenty of power for any of my DeWalt compatible tools. The hammer drill is probably the most demanding and drains batteries faster than the others so I used it to test the battery and it performed flawlessly. The battery works well in all of my DeWalt tools and the charger charges all of my DeWalt batteries just fine. You simply can't go wrong at this price! This battery will last through the job that normally would take 2 or 3 of the smaller 4Ah batteries and it's really not that much heavier. Read more
