A cover (1) of a battery container has one or more conventional apertures (2) closable by plugs for topping-up the individual cells with electrolyte and also has a corresponding number of hollow shafts (3) closed by a wall section (4). The wall section (4) is constructed to be readily broken at (5) to enable, for example, a measuring instrument to be inserted through the shaft (3) to obtain information about the electrolyte. <IMAGE> |
