<p>An end cap assembly (10) for an electrochemical cell, for example an alkaline cell, is disclosed comprising an exposed terminal end cap (20) of single piece construction having a convoluted surface, an electrically insulating member (100) and a metal support disk (70) between the insulating member (100) and the terminal end cap (20). The end cap assembly (10) is inserted into the open end of the cell housing after the cell contents have been supplied. A portion of the end cap surface is a flat annular step (23) which improves contact between the end cap and the electrically conductive portion of a condition tester (155) for the cell which may be integrated into the cell label (180). The annular step (23) is advantageously located at about right angle to the cell's longitudinal axis. The surface step is integral with the end cap and preferably located at about the same level as the shoulder of the cell housing at the end of the cell containing the end cap. The end cap assembly as a whole provides a tight seal for the cell.</p> |
