A battery terminal post of the type for use in electrolytic devices contained by resilient electrolyte-resistant walls, wherein an opening (16) in the electrolytic device wall is radially enlarged to form a bushing (27), into which is inserted a second T-shaped lead alloy bushing (14), into which in turn there is inserted a complementary third bushing (12) of pure lead, which three bushings are then forced into intimate sealing contact by being radially expanded by the action of a punch and die in a swaging operation. |
