Apparatus operable to charge a controlled volume of an electrolyte through a filling opening into a battery case is disclosed. The apparatus comprises an electrolyte charging station, a manifold head having a vacuum outlet and a vacuum passageway connected to the vacuum outlet, an electrolyte reservoir and an electrolyte passageway connected to the reservoir, a manifold positioner operable to move the manifold head to and to support the head in a first position, in a second battery case evacuating position, and in a third battery case filling position, and a valve having a fluid discharge which is surrounded by a tube and is in fluid communication with the filling opening of a battery in the charging station when the manifold is in the second position and when the manifold is in the third position, and is spaced from the battery in the charging station when the manifold is in the first position. The tube is operable to engage the case of a battery in the charging station, around the filling opening therein, and in sealing engagement therewith, when the manifold in the second and third positions, and the valve is operable: when the manifold is in the first position, to prevent the flow of fluid from the vacuum outlet and from the electrolyte reservoir to the fluid discharge of the valve, when the manifold is in the second position, to enable the flow of fluid through the vacuum passageway between the fluid discharge of the valve and the vacuum outlet, and to prevent the flow of fluid between the electrolyte reservoir and the fluid discharge of the valve, and when the manifold is in the third position, to prevent the flow of fluid through the vacuum passageway between the fluid discharge of the valve and the vacuum outlet and to enable the flow of fluid between the electrolyte reservoir, through the electrolyte passageway and the fluid discharge of the valve.
