just buy new batteries.. ive heard horror stories of guys trying to rebuild their batteries themself only to have the tool catch on fire because they dont know what their doing.. if its an older drill chances are you wont even be able to get those batteries anymore

I looked into rebuilding my Ryobi batteries. Cost twice as much as buying a new battery.

Take your ni-cad (only) battery pack and determine polarity of each contact surface.

Then, (I use a 12v car battery charger as a hi voltage DC device) using the same polarity + to + and - to -, briefly touch (1 second at a time) both contact surfaces of your battery pack. It will spark a little.

That's it! Simple and effective. Your battery pack should show good voltage and hold a charge now.

Note; some battery packs are too far gone to be revived by this method but it works most of the time. Cheap too! You have just burned off the small crystalline connections that have formed inside your ni-cad battery that had effectively shorted it out. Burning off these "dendrites" revives your battery.

This sounds like a good way to cook your battery.
