The Invention concerns an electric accumulator (1, 100, 101, 102, 103, 104) of the type with free electrolyte comprising: a container (3) provided with cells (5) adapted to house the plates (8) and to contain the electrolyte (E); a cover (2, 200). The accumulator has a valve device (9) having an inlet (10) that communicates with the cells (5) and an outlet communicating (11) with the external environment (A), to prevent the leaking of electrolyte (E) and to allow the disposai to the outside of the gases that develop inside the accumulator (1, 100, 101, 102, 103, 104) when the pressure in the cells (5) exceeds a predetermined value. |
