Regarding this fancy AA & AAA wall-wart battery charger that Energizer sent in, know ye that it has flashing lights and a 'fuel' monitor so you know how much 'fuel' is in each cell. It charges slow to maximize the number of cycles, and can charge 4 at once, each kind in pairs. Now, about the 'bad battery' detection: it seems rather picky about what it will agree to recharge. Some of my NiMHs are quite new, after all, only a few charging cycles. I don't know! I'm paranoid! It is $20.
