An improved housing system for a multi-cell battery including a container and a cover. The container has a bottom and a plurality of external walls cooperating to define a well and a plurality of internal walls which cooperate with the external walls and the bottom to define a plurality of cell reservoirs for receiving cells of a multi-cell battery. The external walls and the internal walls terminate in an array of edges oriented in a pattern substantially in a plane. The container and the cover are of material amenable to heat bonding. The improvement comprises the cover having an underside with a plurality of zones. Each zone has a respective thickness; one zone is oriented substantially in a plane and generally in register with the pattern of the array of edges presented by the container when the cover is positioned for attachment with the container. The one zone has a thickness which is greater than the thickness of adjacent zones. In the preferred embodiment, the adjacent zones and the one zone meet in transition loci having a radiused transition.
