ABSTRACT:
A method and apparatus to cold form rings or a lead battery terminal with undercuts or overhangs to improve the sealing properties of the rings. The apparatus can be one of a segmented die device and a die device wherein one die member moves relative to the other die member. In either apparatus at least one ring on the battery terminal is transferred from having a first shape into a second different shape with an overhang.
