It will be interesting to see how long your batteries live using this charger. I suspect their life will be shortened since they willl not be getting a full charge. BTW, I noticed yesterday at my nearby WalMart a B&D Universal charger - seems it will rapid charge just about any B&D battery 9.6 v and up. It was about $40.
