Abstract: A container for a battery includes a top portion having a generally rectangular shape and that is configured for coupling to a cover for the battery. The container also includes a plurality of cell containers extending from the top portion for housing wound cells elements. The cell containers have a generally cylindrical shape and are arranged in an offset configuration. The container also includes a structure extending from the top portion in an area of the top portion not supported by a cell container due to the offset cell container configuration. The structure provides enhanced structural rigidity for the top portion in the area of the top portion not supported by a cell container.
