Lid section of an electrochemical battery and battery with such a lid section

The part has a closure stopper comprising charging holes (2) to be locked for filling liquid electrolytes into a housing. The charging holes are arranged in two adjacent rows (8, 9) and offset to each other. The charging openings are interconnected through a common vent channel. The common vent channel intersects the associated charging holes in a tangential manner. Adjacent degassing ducts (4, 5) extend from one another at distance that is not greater than diameter of a receiving chamber (6) i.e. elongated chamber, for an ignition protection frit insert (12).
