A battery terminal post of the type for use in electrolytic devices contained by resilient electrolyte-resistant walls, wherein an opening in the electrolytic device wall is radially enlarged to form a bushing, into which is inserted a second T-shaped lead alloy bushing, into which in turn there is inserted a complementary third bushing 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.
