A sealed, through partition terminal for an electrochemical cell featuring the use of gasketing material to prevent the spread of electrolyte past the terminal seal assembly is disclosed. An orifice formed in a lid of an electrochemical cell accepts a terminal member that is secured to the lid with a fastener threaded onto the terminal member. A shoulder molded on the bottom face of the lid and adjacent to the orifice prevents axial movement of the terminal member while torquing the fastener. A gap formed between the wall of the orifice and the terminal member is filled with gasketing material that is compressed by torquing the fastener. The compressed gasketing material seals any gaps between the terminal member and lid orifice preventing electrolyte leakage.

A sealed, through partition terminal for an electrochemical cell featuring the use of gasketing material to prevent the spread of electrolyte past the terminal seal assembly. An orifice formed in an inner lid of an electrochemical cell accepts a terminal member that is secured to the inner lid with a fastener threaded onto the terminal member. A shoulder molded on the bottom face of the inner lid and adjacent to the orifice prevents axial movement of the terminal member while torquing the fastener. A gap formed between the wall of the orifice and the terminal member is filled with gasketing material that is compressed by torquing the fastener. The compressed gasketing material seals any gaps between the terminal member and inner lid orifice preventing electrolyte leakage.

An up-and-through battery intercell connection for electrochemical batteries or cells is disclosed featuring battery partition wall extensions formed on battery partition walls located within a battery container through which lead intercell connector nuggets are secured to provide electrical connection between battery intercells. A battery container top is formed with recesses to accept the battery partition wall extensions. The container top is further formed with adhesive channels to accept a paste adhesive that allows the battery container top to be secured to the battery container without having to invert the battery during manufacture.
