I replaced the cells in my 14.4v B&D drill. It cost about $20-$25 and required some soldering. The capacity of the new cells is greater than the old ones, so it was a benefit all the way around. I recall there were some good descriptions of the process on the instructables site.
More recently, I've dropped the drill a few times and the case of the battery is cracked. I think that my next move will be to one of the new the lithium models. I'll probably go with the lighter 12v though, and stick with a corded drill for more heavy duty jobs.
