The device has a transparent viewing rod with a battery observation surface at one end and a tip formed by a conical reflection surface at the other end carrying a ball cage through which electrolyte flows with an inclined channel for at least one ball of defined specific weight. The channel extends above the tip and has an upper wall with an opening for the tip aligned with the reflective surface at its transition to the cylindrical rod surface. The device has a transparent viewing rod (3) with a battery observation surface at one end and a tip (5) formed by a conical reflection surface (4) at the other end, to which is attached a ball cage (1) through which the electrolyte flows and that has an inclined ball channel (9) for at least one ball (12,13) of defined specific weight. The channel extends above the height of the tip and has an upper bounding wall (14) with an opening for the tip aligned with the reflective surface at its transition to the cylindrical surface (6) of the rod. |
