Black & Decker 12V battery pack fails to charge?
I have a rechargeable Firestorm 12V battery pack (model A9275) for a cordless drill. When I try to recharge it, the red "Battery Charging" light flashes on, then is immediately replaced by the green "Battery Full" light. No charging takes place. However I know that the battery is discharged as the drill does not operate when this battery is attached, but will work with a different battery. Any ideas ?
