I have a $120 smart charger I used for charging up model airplane batteries. It intelligently plots the voltage curve on batteries, and thus can fast charge at a VERY high rate but still detect when they're fully charged, and automatically switch to a trickle charge. I can charge a Nimh from fully drained in as little as 15 minutes, and nicd even faster
I tell you what, those suckers get HOT if you overcharge them.
