RE: Chargers
If you're just charging NiCd's pretty much any programmable charger will work. The whole point of a peak detecting charger is to charge fast though. Slow is not better. It's safer. The point is to not damage your batteries, and a quality peak detecting charger can fast charge without damaging your batteries. If you just want to charge at 100 mah though, get a wall wart and a 24 hour timer.
