The invention concerns an electric accumulator (100, 100a, 101, 102, 103, 104, 105) comprising: a container (2) with many cells (4) adapted to house the plates (5) and to contain the electrolyte (E); a cover (1). The accumulator also comprises a reservoir (6) adapted to contain a topping up liquid (R) of the electrolyte (E) present in the cells (4), communicating with the cells (4); control means (9) of the level (L) of electrolyte (E) in the cells (4) adapted to prevent/allow the flow of topping up liquid (R) into the cells (4) when the corresponding level (L) of electrolyte (E) is higher/lower than a predetermined level (S). |
