Abstract
Battery parts, such as battery terminals, and associated systems and methods for making the same are disclosed herein. In one embodiment, a battery part has a base portion that includes one or more undercut sealing portions, each having a root and a lip. The lip can flare outwardly from the root to define an undercut between the root and the lip of the sealing portion. In some embodiments, the battery terminal can include adjacent sealing portions having opposing undercuts defined by overlapping lips of the adjacent sealing portions. Another embodiment includes a forming assembly for use with, for example, a battery part having a bifurcated acid ring with spaced apart lips. The forming assembly can include movable forming members that can be driven together to peen, crimp, flare or otherwise form the lips on the bifurcated acid ring.
