Accumulator, in particular lead accumulator

The battery has a housing with several cells, a lid with a lower part and an upper part at a distance from it that seals the lower part and labyrinthine outlet channels for oxygen separation between the upper and lower parts. The lower part has a break near the upper part bounding on the outlet channels. The cells in the region of the break are separated liquid-tight from each other by cell separating wall sections and closed by the upper part. The battery has a housing with several cells, a lid (4) closing the housing with a lower part (5) placed on the housing and an upper part (6) at a distance from the lower part and that seals the lower part and labyrinthine outlet channels (K) for oxygen separation between the upper and lower parts. The lower part has a break through (10) near the upper part bounding on the outlet channels and the cells in the region of the break through are separated liquid-tight from each other by cell separating wall sections and closed by the upper part.
