The battery worked well when i first got it but after a year it was pooped out and would not take much of a charge. This was my second replacement so i got a Bosch to replace the dewalt. Dewalt had two batteries that came with it one of them was no good.

There are two DeWalt replacement battery pack types that I know of. The one that has the XR behind the voltage is a hotter battery than the standard battery. The XR battery is about 1/2 inch longer and may weigh a tiny bit more but its worth it.

I plan on buying a second XR battery. I have purchased two standard sets and they last about a year with me. Sometimes I use them a lot and sometimes they sit for a while betwen use. So far this battery is a gem.

Please note that this is the XR battery pack. Most 9.6 volt tools from DeWalt come with the standard battery pack. The XR pack features 25% more runtime. So if you're thinking about buying a new tool instead of replacement batteries, be aware of the difference in the batteries. By the way, higher voltage DeWalt replacement batteries are labeled XRP. These proide 40% more runtime than the standard batteries. Also note that the extended runtime batteries are slightly larger and heavier than the standard versions.

Who would pay $ for one battery; when you could purchase 2 batteries, a charger and the drill itself for $$???.
Why on earth do manufacturers price disposable items such as this so high?
I for one will purchase a new drill----------but it will not be a DeWalt!
Perhaps the same problem will occur with another brand, but I will feel better at the start giving Bosch or Porter Cable my commerce.
