Abstract
A process for improving leakage resistant in a galvanic cell is provided. This is done by making an improved grommet and metal cover. The process comprises swelling a grommet which has been placed tightly around the periphery of a metal cover until the grommet is loose upon the metal cover, forcing a sealant solution between the swollen grommet and metal cover and then shrinking the grommet to substantially its original size to trap the sealant compound between the grommet and metal cover.
