An external electrical connector is disposed on the second end face. All of the battery cells are connected to the external electrical connector. The battery cells are charged and discharged through the external electrical connector. A cell holder secures several of the battery cells. An inner positional securing element is provided on an inner side of a sidewall of the housing and the cell holder interacts with the positional securing element.
