Hey guys, I was wondering how do you take care of the sealed lead acid rechargeable flashlights? I have bought 2 and they both broke .. the million candlepower kind. Well I now bought another one but this is a work light and is a fluorescent rechargeable light with a sealed lead acid battery in it. I would like for this one to last and wanted some advice. All I think it has is a charge indicator and I bet there is nothing really inside that controls how the battery is charged other than a simple resistor or something inside it as I found in one of the other million candlepower flashlights I broke open. Any ideas or simple charging circuits that I can build for lead acid batteries?
