Had to get a new battery. I can't say I took very good care of the OEM battery, it ran out of water twice. So started looking on the net, I wanted a battery that would drop in with no mods and was maintenance free. Found a site www.batterystuff.com and followed the tabs. Found a Power Sonic battery that is maintenance free, $54 with free shipping. Ordered the battery and installed it. Fits right in no mods.
