The first contact lug is preferably welded onto the first end face. The second contact lug is preferably welded onto the first end face. As a result, the cell therefore preferably comprises a first contact lug configured as a sheet-metal part that is welded onto the first end face and has a planar section extending in a plane parallel to the first end face, and comprises a second contact lug configured as a sheet-metal part that is welded onto the second end face and has a planar subsection extending in a plane parallel to the second end face and has a subsection angled away from the plane and extends as far as into the plane of the planar section.

The cell is preferably designed in the form of a straight circular cylinder. The planar end faces are therefore preferably of circular design and oriented parallel to one another. The axis of the cylinder, which is oriented perpendicularly to the end faces, preferably runs through the center of the end faces.

The housing parts are preferably of cup-like design. In addition to preferably round bases, they each preferably have a hollow-cylindrical casing. The outer faces of the bases preferably form the end faces.

An annular seal composed of plastic and electrically insulates the housing parts from one another is usually arranged between the two metal housing parts. Furthermore, the seal ensures liquid-tight closure of the cells.
