The invention relates to a filling system for a secondary battery. A stopper is inserted in the battery and has a liquid channel passing through it, the passage being closable by means of an inlet valve controlled by the level of the liquid in the battery. The stopper cooperates with a filling nozzle which is connected to a storage container for the filling liquid. The nozzle is movable relatively to the stopper and may be inserted through a closable filling opening of the stopper. The nozzle is provided with an outlet opening associated with an outlet valve which cooperates with and is operated by an opening element carried by the stopper when the nozzle is inserted into the stopper. |
