Disclosed is a wirelessly rechargeable battery. The battery is comprised of an elongate battery casing (formed from 2 and 3) having a longitudinal axis. Within the casing (2 and 3) are a rechargeable storage device (4), a plurality of power receiving coils (8, 9) and a charging circuit (10). The coils (8, 9) are disposed at an angle of between 30 to 60 degrees to the longitudinal axis of the casing (2 and 3). The charging circuit (10) controls the supply of power from the coils (8, 9) to the storage device (4).
