Abstract
Abstract A reserve cell has cylindrical electrodes surrounding a cell component container, all in a cylindrical housing. A shim has a circular groove accepting one end of an electrode and a socket holding one end of the container. The outer edge of the shim abuts the inner wall of the housing. This arrangement maintains spatial relationships of the cell.
