Abstract: An electric accumulator battery, constituted of a series of independent modules, each of which comprises a recipient with a lid subdivided into cells in which positive and negative helically wound electrodes and an intermediate separator are housed. The recipient of each module comprises an outer wall, of straight rectangular prismatic shape, and an inner wall which defines three cylindrical cells (9) of coplanar axes, tangent to each other and closed on the lower base. Axial ventilation passages are defined between these two walls, which pass through the base through openings (5 and 6).

Abstract: An electric accumulator battery, comprising a recipient which is closed by means of a lid composed of a lower lid and an upper lid joined together, delimiting an intermediate chamber. The lower lid has filling holes (15), in which closing stoppers with a gas outlet valve are assembled, which end in the chamber defined between the two lids. The upper lid has openings (10) for the passage of the connection terminals (3), and at least one gas outlet hole (12). The two lids have facing ventilation openings (7-7′).

Abstract: A multicell electric storage battery with a prismatic container (1) and cylindrical cells, which comprises throughpassing vertical conduits (15-16) opening through the lid and bottom and disposed among adjacent cells and intended for the circulation of air or another coolant and for the passage of threaded anchoring rods (17). The cylindrical walls of the cells include a planar upper segment with an opening through which the electrical connection of adjacent cells is made.
