Here is the battery from one of the drills. I have wound some tape around to make the pack a bit stronger. 

Newer drills may have smaller and lighter batteris that may be Lithium - this is not bad. In my case it is Ni-Mh. It gives around 30-40 minutes of spinning the pipe around. The recharging time is around 3 hours.

The battery ends had some wholes in them and I used two screws to place all the cables on them.
