Abstract: A rechargeable battery pack (10) for holding one or more batteries (19) and for connecting to an battery powered device (11). The battery pack batteries supplies electrical power to the peripheral device. The battery pack includes a case for holding at least one battery, a recharging circuit (57) connected to the at least one battery and disposed in the case and a plug (50) with prongs for electrically connecting the recharging circuit to an external source of electrical power. The plug rotates about a connection to the case from a first operational position having the plug mounted flush with the case and the prongs recessed in the case, to a second operational position with the prongs projecting from the case. The second and third operational positions of the plug are approximately orthogonal to the first operational position. The prongs are electrically connected to the recharging circuit in all operational positions.
