Abstract: An integral battery and recharger is described. The battery includes a battery housing, battery terminals and plug pins for location in a plug socket and operable to effect recharging of the battery when connected to an AC supply. The battery housing is generally designed to be received in a close fitting cavity (33) of a battery powered device. The part of the housing from which the plug pins project is designed to be sufficiently spaced, in use, from the walls of the cavity to allow the plug pins which project therefrom to fully extend part and the cavity. Preferably, the side from which the pins project extends at substantially 45° with respect to the said adjacent sides to form the third side of a three sided battery housing. A method of using and recharging a battery located in a battery powered device is also described.
