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.

1. A method of making a battery part comprising: forming a battery part having a first sealing portion and at least a second sealing portion extending around an exterior portion thereof, wherein the first sealing portion and the second sealing portion include a first lip and second lip, respectively
1. A method of making a battery part comprising: forming a battery part having a first sealing portion and at least a second sealing portion extending around an exterior portion thereof, wherein the first sealing portion and the second sealing portion include a first lip and second lip, respectively, extending therefrom;bending the first lip in a first direction; andbending the second lip in a second direction, generally opposite to the first direction, wherein bending the second lip defines an undercut region between the second lip and the exterior portion of the battery part, and wherein the first lip is at least partially disposed within the undercut region. 2. The method of claim 1 wherein bending the first and second lips includes: positioning the battery part between a first forming member and a second forming member; andpressing the first forming member and the second forming member against the battery part to bend the first lip and the second lip. 3. The method of claim 2 wherein pressing the first and second forming members against the battery part bends the first lip and the second lip toward each other. 4. The method of claim 1 wherein forming the battery part includes casting the battery part. 5. The method of claim 1 wherein the battery part includes a longitudinal axis, wherein the first and second directions are generally parallel to the longitudinal axis, wherein the first and second sealing portion is spaced apart from the first sealing portion in the first direction, wherein the second lip at least partially overlaps the first lip in the second direction, and wherein the first and second lips are spaced apart from each other in a third direction generally perpendicular to the longitudinal axis. 6. The method of claim 1 wherein bending the first and second lips includes: rotating the battery part; andwhile rotating the battery part, contacting the first and second lips with a forming member. 7. The method of claim 6 wherein the forming member is rotatable, and wherein contacting the first and second lips with the forming member includes radially pressing against the first and second lips with the forming member. 8. A method of making a battery part, comprising: forming a battery part having— a base portion;a first sealing portion having a first lip extending radially outward from the base portion; anda second sealing portion axially spaced apart from the first sealing portion and having a second lip extending radially outward from the base portion;flaring the first lip in a first direction; andflaring the second lip in a second direction, generally opposite the first direction so that the second lip axially overlaps the first lip. 9. The method of claim 8 wherein, after flaring the first and second lips, the first lip is radially offset from the second lip. 10. The method of claim 8 wherein flaring the first and second lips includes flaring the first and second lips substantially simultaneously. 11. The method of claim 8, further comprising forming a through-hole extending through the battery part in the axial direction. 12. The method of claim 8 wherein the battery part further includes a third sealing portion having a third lip extending radially outward from the base portion, wherein the first sealing portion is axially disposed between the second and third sealing portions and has a fourth lip extending radially outward from the base portion, and wherein the method further comprises: flaring the fourth lip in generally the second direction; andflaring the third lip in generally the first direction so that the third lip axially overlaps the fourth lip. 13. The method of claim 12 wherein the first sealing portion is radially offset relative to the second and third sealing portions. 14. The method of claim 12 wherein the second and third sealing portions have substantially similar dimensions, and wherein the second sealing portion is inverted relative to the third sealing portion. 15. The method of claim 12 wherein flaring the first, second, and third lips includes: positioning the battery part between at least two forming members; andpressing the forming members against the battery part to flare the first lip, the second lip, the third lip, and the fourth lip. 16. The method of claim 15 wherein pressing the forming members against the battery part flares (a) the first lip and the second lip toward each other, and (b) flares the third lip and the fourth lip toward each other. 17. The method of claim 12 wherein flaring the first, second, third, and fourth lips includes: rolling at least one of the battery part and a die; andengaging the battery part with the die. 18. A method of making a battery terminal, comprising casting a battery terminal having first and second annular acid rings extending around an exterior portion thereof;pressing against the first annular acid ring to flare a first lip portion of the first annular acid ring outwardly from a first root portion of the first annular acid ring; andpressing against the second annular acid ring to flare a second lip portion of the second annular acid ring outwardly from a second root portion of the second annular acid ring and toward the first lip portion wherein flaring the second lip portion defines an undercut region between the second lip portion and the exterior portion of the battery terminal, and wherein at least a portion of the first lip portion is disposed within the undercut region. 19. The method of claim 18 wherein the undercut region is a first undercut region, and wherein flaring the second lip portion defines a second undercut region between the second lip portion and the exterior portion of the battery terminal.
