A non-leaking flexible plastic bellows connection between the cover and the lead terminal of a secondary battery expandable plate, including circumferential grooves around the terminal for molding thereto one end of the plastic bellows while the other end is sealed to the plastic cover of the battery or formed integral therewith. The grooves in the upper end of the lead terminal may be formed in the terminal or in a sleeve of softer lead composition integrally attached to the end of the terminal. The lead cell connectors are integrally attached to the upper outer ends of these lead sleeves or terminals above the grooves therein.
