ABSTRACT:
A battery assembly having an improved case, simplifying manufacture, includes a tubular case having an internal space, an open end, a closed end, a cell element in the internal space of the case, and a cap closing the open end of the case, wherein the internal sectional dimension of the case is largest at the open end and smallest as the closed end while the external dimensions of the case are uniform. The change in internal dimensions may be provided by a tapering thickness of the case. Because of the tapered opening within the case, the cell element is easily inserted into the case.
