Be caredul with your power tools, my cousins son, 26yrs old, was killed last week when a dewalt battery got pinched as he was working on a vehicle, the battery exploded and shrapnel went through his hearrt, at times i find myself "hammering" with the bottom of the drill (battery) as that is what is in my hand at that moment, i will refrain from this going fwd, but wanted to let others know so they understand these battery cam be quite damgerous.
