Abstract: A relatively flat, rectangular, box-shaped, rechargeable, battery pack has a multi-positionable plug with prongs. The plug can be appropriately positioned for recharging the pack by insertion of the plug into either a European-type, deeply recessed receptacle, in a shallow recessed receptacle or in a flush, non-recessed United States-type receptacle. The pack is adapted to interchangeably fit into a pocket or any one of a plurality of pockets in a device in which the pack is to be employed. The prongs on the plug furnish voltage to the device when the pack is in a device pocket and furnish voltage to the pack during recharging. In a discharge mode, the plug is depressed and latched within the battery pack leaving only the prongs external of the battery pack for insertion into the device to be powered. The plug is likewise depressed for recharging in a flush-type receptacle. The pack discharge circuitry is actuated by a mating post in the housing of the device to be powered.
