Hey guys, I was wondering if the Rayovac hybrid charger has any mechanisms to shut off the charge other than the timer itself? I am willing to open it if you guys are able to identify if it does or not just by looking at the components on the inside. And would it in any way ruin the charger itself? I know its probably a crappy charger but its either that or this other crappy Energizer AccuRecharge charger that takes 15 hours to charge. Does anyone know if that charger is any good at all? I don't really care about how long it takes to charge just don't want to kill the battery is all. Thanks for your time.
