My 1300 mah Vision Spinner Fat battery is no longer doing anything properly. It doesn't hold a charge. When the battery is on the charger, the white light on the button blinks, and it shows green on the charger, but the battery is "dead". This battery is pretty damn new, and it WAS my favorite battery ever cuz of how well it worked. I just don't understand what could be wrong. I've only had the battery for a month and have used it less than that. Any ideas?
