Abstract
A method of establishing a hermetic seal about a terminal post of a battery comprises the step of forming a plurality of concentric ridges around the terminal post, positioning a tubular protrusion integral to the cover about the surface region of the terminal post containing the concentric ridges, and applying a radially directed force against the collar of such magnitude to cause the tubular protrusion to flow into intimate contact with the post and the concentric ridges.
