<p>The aim of the invention is to implement a simple and during the use of the storage battery always available level indicator, by which it could be possible to visually control not only the level of the electrolyte inside the storage battery but also the availability of the required voltage inside the battery. The indicator is designed as a battery plug (1), which is equipped with a light transmitter (2). The specified light transmitter (2) is equipped with a passage (21) running axially within it, which is filled with the electrolyte and which contains two floaters (3, 4) located one above the other. The upper floater (3) is selected in such a way that its density is lower from the lowest possible density of the electrolyte within the battery cell. The lower floater (4) is selected in such a way that its density is lower from the maximum possible density of the electrolyte within the battery cell and smaller from the maximum density or specific weight of the electrolyte available within the battery cell. Inside the wall (22) of the light transmitter (2) there are two reflective elements (223, 224) so that the lower reflective element (224) is located on one end of the passage (21), while the upper reflection element (223) is located on the opposite side.</p> |
