The invention relates to a lead-acid accumulator having a housing (1), which has a plurality of cells (2), and having a cover (3) which closes the housing (1) and in which in each case one chamber having deflection webs (13, 13', 13'') for acid precipitation is constructed between a lower cover (3') and an upper cover (3''), which is arranged at a distance from said lower cover (3'), for each cell (2), the cells (2) having in the cover (3) in each case one filling and possibly inspection opening (6) which can be closed by a closure plug (10) and is surrounded by an annular web (11) which has a venting and flow-back opening (12), and at least one ignition protection device (14) in the cover (3) being allocated to the cells (2). In order that, even in the tilted state, no acid can penetrate into the ignition protection device or to the outside in a limited time, for example within 20 hours when it is on its side and within one hour when tilted, the venting and flow-back openings (12) in the annular webs (11) and/or the deflection webs (13, 13', 13'') are arranged and/or constructed in the chambers (4) in such a manner that in all the tilted positions of the housing (1) onto its four side walls (17), the acid level (19) is below that maximum level above which the acid (18) flows into the ignition protection device (14). <IMAGE> |
