A battery has a prismatic metal housing that includes a rectangular base having a base inner side and a base outer side, a rectangular cover having a cover inner side and a cover outer side, the size and shape of which substantially correspond to that of the base, and four rectangular side elements connecting the base and the cover and each have an inner side and an outer side. The at least one individual cell is a winding having a first and a second end face and the first end face faces in the direction of the base and the second end face faces in the direction of the cover. Conductor vanes electrically connect to the base of the metal housing exit from the first end face. These are fixed to an electrically conductive collecting and positioning means inserted into a receiving means in the base of the metal housing and fixed therein.
