Abstract: An improved battery of the type having a spiral wound core (32) surrounded by a container (38) is disclosed in which an improved terminal tab (10-32, 44-50) is attached to the end of the core inserted into the container, the terminal tab comprising an outwardly extending tab member (24) bent back over the base (12) of the terminal tab and along the side of the core. A protrusion (46) on the base contacts the bent tab member to minimize compression by the tab member of the circumferential edge of the end of the battery core when the core has been inserted into the container. An improved method of assembling such a battery also is disclosed.
