Abstract: A battery cell has an electrode plate pack arranged in a casing and provided with a terminal of lead material that extends through a cover opening of the casing cover of the casing. A plastic material cap is placed onto the terminal. The cap has an inner side provided with a circumferentially extending shoulder and an exterior side provided with a circumferentially extending support web. A sealing element is arranged at the inner side of the cap between cap and terminal and is positionally fixed by the circumferentially extending shoulder. The casing cover rests on the circumferentially extending support web. Cap and casing cover are welded to each other. A threaded sleeve of nonferrous metal is embedded in the lead material of the terminal and is aligned with an insertion opening of the cap. The threaded sleeve receives a connecting screw to be passed through the insertion opening.
