Abstract
A module battery of sealed alkaline storage battery comprises a plurality of cells stacked in one direction each of which comprises a battery casing of a synthetic resin, an electrolyte and an electrode group accommodated in the battery casing and a lid with a safety bent sealingly fitted to the opening of the battery casing; wherein the cells are bound in the direction of stacking by binding members for coupling the end plates at the ends of the stacked battery assembly to each other; the cells are butted to each other by a plurality of parallel ribs formed on the outer surface of the battery casing along the direction of stacking thereby to form spaces for allowing air flow between the cells, a thickness of the side wall of the battery casing along the direction of stacking is 1 to 3 mm, a rib height 1 to 2 mm, a rib interval 10 to 15 mm, and a rib width 3 to 10 mm.
