+BadAndy Posted September 13, 2003 Share Posted September 13, 2003 It's the big secret of the Battery industry. Yes, Alkaline batteries can be recharged numerous times. I've been doing it for years. There are 2 ways to do this. The proper way is using vented batteries with a pulsed charging system. This method works well but requires a larger outlay of special batteries and a special charger. The other way is the way I do it, and requires only your old dead coppertops and a Wallyworld nicad charger (about the same price as an 8pack of aa's). The cheep way does require a bit more attention. The nicad charger pumps out the juice a bit faster, so you can't leave the batteries on charge for more than 5 or 6 hours. If you leave them in they will eventually bloat and leak, ruining your charger. I use coppertops exclusively because I know they are vented. There may be other vented batts but I've never torn them apart to look. I limit my charge/discharge to 4 cycles, just to ensure they never bloat and always have full capacity. Do not use cheap offbrand batteries as they are likely not vented and will bloat. Stop tossing those perfectly good alkalines, help protect the environment and save a ton on batteries.
