Abstract
A battery including a container, a cover and an end wall stiffener block. The container is molded with a compartment between an outer and an inner end wall into which the stiffener block is inserted. The stiffener block is preferably made of a stiff plastic or of metal. The stiffener block and compartment are sized so that a contacting relationship is maintained between the inner wall, the block, and the outer wall. The inner wall also maintains a contacting relationship with the active internal components of the battery. During assembly, both the inner and the outer end walls are heat-sealed to the cover, such that the compartment is entirely sealed.
