ABSTRACT:
A battery unit is designed for battery-operated appliances such as cordless telephones, notebook computers, video cameras, etc., and comprises an envelope within which one or several electrochemical cells are accommodated as well as electrical connection contacts, which envelope has at least approximately the shape of a closed rectangular block. To provide a satisfactory and stable guiding, ridges and/or grooves are present at least adjacent the side surfaces of the envelope for mating with corresponding grooves and/or ridges of a housing of a battery-operated appliance to provide a sliding possibility for the battery unit. The envelope is further provided with external asymmetrical locating portions for cooperating with correspondingly shaped and positioned locating portions of the battery-operated appliance so as to prevent an incorrect insertion of the battery unit. The connection contacts are present adjacent the lower surface of the envelope.
