Sealed storage battery

摘要

The sealed storage battery includes a monoblock container (10) in which at least two cell rows (11, 12) are arranged adjacent to and in parallel to each other. Each cell row includes a plurality of cells (11a, 11b, 12a, 12b). A cover (33) closes the top of the monoblock container (10). There are first intercell connectors (37, 38, 39, 40) for connecting adjacent cells of the same cell row in parallel and second intercell connectors (47a, 47b) for connecting adjacent cells of different cell rows in parallel. Positive electrode terminals (41, 43) and negative electrode terminals (42, 44) are arranged on the cover to correspond to the respective cells. The adjacent cells in each cell row have interconnecting gas phases. The storage battery has less variation of the characteristics of its cells and all of the cells can be discharged when the positive electrode terminals and negative electrode terminals are selected for use in any combination.
