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.

Claims (22)

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 at least one of the positive terminal and the negative terminal further comprise an electrically conductive cap mounted on the at least one of the positive terminal or the negative terminal, wherein the electrically conductive cap comprises no externally exposed 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 electrically conductive 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 electrically conductive cap is further comprised of a polymer or resin.

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

6. The battery of claim 1 , wherein the electrically conductive cap connects to a battery cover using one or more components selected from the group consisting of mechanical press-fit, thermal press-fit, adhesive, glue, spin welding, heat sealing, laser welding, or an overmolded ring.

7. The battery of claim 1 , wherein the electrically conductive cap further comprises torque ribs.

8. The battery of claim 1 , wherein the battery comprises an electrically conductive cap on both the positive terminal and the negative terminal.

9. The battery of claim 1 , wherein any exposed surface of the battery is lead-free.

10. A battery terminal assembly composed of a lead battery terminal having an electrically conductive cap positioned over the terminal, wherein the electrically-conductive cap comprises at least a lead free external surface.

11. The battery terminal assembly of claim 10 , wherein the terminal comprises an exposed portion comprising lead and the electrically conductive cap covers exposed terminal lead when assembled on a lead acid battery.

12. The battery terminal assembly of claim 10 , wherein the electrically conductive cap couples to the terminal by way of a friction fit.

13. The battery terminal assembly of claim 10 , wherein the electrically conductive cap comprises a conductive cage.

14. The battery terminal assembly of claim 10 , wherein the electrically conductive cap is comprised of a material selected from the group consisting of copper, brass, stainless steel, or nickel.

15. The battery terminal assembly of claim 10 , wherein the electrically-conductive cap is further comprised of a polymer or resin.

16. An electrically conductive cap for a lead acid battery terminal comprising:

a recess configured to receive a lead acid battery terminal; and

at least a lead free external surface.

17. The electrically conductive cap of claim 16 , wherein the electrically conductive cap comprises an electrically conductive portion comprising a conductive cage.

18. The electrically conductive cap of claim 16 , wherein the electrically conductive cap is comprised of a material selected from the group consisting of copper, brass, stainless steel, or nickel.

19. The electrically conductive cap of claim 16 , wherein the electrically conductive cap is further comprised of a polymer or resin.

20. The electrically conductive cap of claim 16 , wherein the electrically conductive cap further comprises torque ribs.
