A series of cell fill valves are interconnected by a series of hoses and T-connections, one to each battery cell. Each cell fill valve is controlled by a ball in a seat in a single fill opening. The ball is controlled by a float on a pivotable lever arm with an end finger which holds the ball up to admit water with the float down and allows the ball to lower onto the seat as the cell fills causing the float to rise to a shutoff level when the cell is filled to a desired level.
