Abstract
A battery structure arranged to avoid the inefficiency problems which normally accompany container bulging in conventional absorbed electrolyte batteries such as sealed lead-acid batteries. The battery container is separated by partition walls into a plurality of working cells into which are closely fitted conventional stacks of plates and separators. The partition walls hold the plates and separators in intimate contact necessary for proper operation of the battery. Bulge compensating end cells are provided at either end of the battery between the working cells and the container end walls to accommodate pressure variations during battery operation. Compression means associated with the bulge compensating end cells maintains the plates and separators in intimate contact to maintain battery efficiency while permitting the container end walls to bulge.
