Abstract

Disclosed is a non-lead conductive cap for a battery terminal and battery. The battery may comprise a battery housing and a positive and negative terminal, the positive and negative terminal being accessible through the battery housing; wherein the positive and negative terminal further comprise an electrically conductive cap mounted on both the positive and negative terminal, wherein the electrically conductive cap does not comprise lead.

First claim

1 . A battery having a battery housing and a positive and negative terminal, the positive and negative terminal being accessible through the battery housing; wherein the positive and negative terminal further comprise an electrically conductive cap mounted on both the positive and negative terminal, wherein the electrically conductive cap does not comprise lead.

2 . The battery of claim 1 , wherein the electrically conductive cap comprises an electrically conductive portion comprising a conductive cage.

3 . The battery of claim 1 , wherein the cap is comprised of a material selected from the group of copper, brass, stainless steel, or nickel.

4 . The battery of claim 3 , wherein the cap is further comprised of a polymer or resin.

5 . The battery of claim 1 , wherein the cap further comprises an overmold.

6 . The battery of claim 1 , wherein the cap further comprises torque ribs.

7 . A battery comprising:
a housing comprising a cover and a battery element; a terminal facilitating electrical connection with the battery element which extends through the cover; and an electrically-conductive cap which receives a terminal;
wherein the electrically-conductive cap does not comprise lead.

8 . The battery of claim 7 , wherein the terminal comprises lead and the electrically-conductive cap covers all terminal lead.

9 . The battery of claim 8 , wherein electrically-conductive cap couples to the terminal by way of a friction fit.

10 . The battery of claim 8 , wherein the electrically-conductive cap connects to the using one or more components selected from the group of thermal press-fit, adhesive, glue, spin welding, heat sealing, laser welding, or an overmolded ring.

11 . The battery of claim 7 , wherein the electrically-conductive cap comprises a conductive cage.

12 . The battery of claim 7 , wherein the electrically-conductive cap is comprised of a material selected from the group of copper, brass, stainless steel, or nickel.

13 . The battery of claim 7 , wherein the electrically-conductive cap is further comprised of a polymer or resin.

14 . A battery having a battery housing and a terminal, the terminal being accessible through a battery housing; wherein the terminal does not comprise lead.

15 . The battery of claim 14 , wherein the housing comprises a cover, and the cover comprises a bushing, the bushing receiving the terminal.

16 . The battery of claim 15 , wherein the bushing comprises lead and is provided below a surface of the cover.
