A lead acid accumulator (1) with bottom connection comprises one or several pairs of accumulator cells (2, 3), each pair of cells being enclosed in a common cell vessel (4) with a liquid-tight partition wall (5) between the separate cells. The cell has a cover (6) with bores (7, 8) for the pole posts (9, 10). Each cell includes a positive (11 or 12) and a negative (13 or 14) group of electrodes, each of which is connected to a corresponding connection strap, one (15) being located above ana the other (16) below the electrode plates. The lower connection strap (16) is common to the two cells and is passed from one cell to the other through the partition wall. The two connection straps in each cell are arranged substantially mutually parallel and are located in a plane (29) substantially going through the centre axes (30 and 31) of the connection straps and through the centres of gravity (32) of the electrode plates. The upper connection straps in the cells are rigidly connected to the cover (6) by means of pole posts (9 and 10) which are substantially located in the plane through the centre axes of the connection straps. The lower common connection strap is supported by at least two shock-absorbing members (24 and 25) arranged on either side of tne partition wall. The pole posts are rigidly connected to the cover by means of a mechanical connection which prevents axial movements in the bores. |
