A device for filling or topping-up batteries, including a trolley, a reservoir for acid or distilled water, and conduits for connection to the inlet and the outlet ends of a series of filler devices, one on each battery cell. At the end of the series a conduit is connected to a sump on a trolley. A pump draws liquid by siphon from the reservoir through the filling devices to the sump. A level responsive switch in the sump is used for terminating the filling operation which can be performed automatically by connecting the conduits and switching on the equipment. A timer and an air valve ensure that all the liquid is sucked out of the line after the cells have been filled before the pump is switched off. Automatic connections connect the inlet and outlet to exhaust through explosion minimizing vents once the conduits have been disconnected.
