A battery refill indicator including a cap having a screw type base and an enlarged cover including a central opening and a float-type liquid level indicator supported by said cap and including a stem extending outwardly through said central opening in said cap and a float connected to the stem in a position to be suspended within the electrolyte in the battery cell. The stem is limited in its upward travel to a height less than the height of the battery cables and the float is adapted to be adjusted in length to accomodate different size batteries. A guide disc is provided in the cap which limits the upward travel of the indicator and also acts as a splash guard.
