Would not even consider Nicads any longer.
First they don't hold a charge loosing 10% of their charge per day.
Second, cadmium is really toxic to the env. Lithium is not toxic by
comparison.

Don't know about your NiCads, but the two DeWalt XRP 18v NiCad
batteries I've got are the ones that came with the six tool set I
bought over five years ago. They charge properly and work fine.

Sure, Li-Ion are better, but they and the tools they power cost more.
