Abstract

Disclosed is a lead acid battery including a housing having an exterior. The battery also includes a lead terminal extending through the housing to the exterior of the housing. A coating covers the lead terminal such that there is no exposed lead exterior to the housing.

First claim

The invention claimed is:

1. A lead acid battery comprising:
a housing having an exterior;
a lead terminal extending through the housing to the exterior of the housing; and
a coating covering the lead terminal such that there is no exposed lead exterior to the housing, wherein the coating is selected from the group consisting of tin, zinc, brass, copper, stainless steel, nickel, and alloys thereof.

2. The lead acid battery of claim 1 , wherein the coating includes an arc-sprayed conductive coating comprising zinc or tin.

3. The lead acid battery of claim 1 , wherein the lead terminal comprises a concave depression on a top surface thereof.

4. A lead acid battery comprising:
a housing having an exterior;
a lead terminal extending through the housing to the exterior of the housing, wherein the lead terminal comprises a concave depression on a top surface thereof; and
a coating covering the lead terminal such that there is no exposed lead exterior to the housing, wherein the coating comprises a conductive coating portion and a non-conductive coating portion, wherein the non-conductive coating portion is provided in the concave depression.

5. The lead acid battery of claim 4 , wherein the non-conductive coating portion includes a coating selected from the group consisting of epoxy resin and polymer.

6. The lead acid battery of claim 4 , wherein the non-conductive coating portion is provided on a side of the lead terminal.

7. The lead acid battery of claim 1 , wherein the lead terminal is a positive terminal, wherein the lead acid battery further comprises a negative terminal.

8. The lead acid battery of claim 7 , wherein the positive terminal includes a first coating, and the negative terminal includes a second coating.

9. A lead acid battery comprising:
a housing having an exterior;
a lead, positive terminal extending through the housing to the exterior of the housing;
a first coating covering the lead terminal such that there is no exposed lead exterior to the housing;
a negative terminal extending through the housing to the exterior of the housing; and
a second coating covering the negative terminal, wherein the first and second coatings are different materials.

10. The lead acid battery of claim 1 , further comprising a battery element and a strap, wherein the battery element is coupled to an end of the strap.

11. The lead acid battery of claim 10 , further comprising a post of the lead terminal, wherein the strap leads to the post.

12. The lead acid battery of claim 11 , further comprising a bushing provided within the housing, wherein the post of the lead terminal extends through the bushing.

13. A lead acid battery comprising:
means for housing the lead acid battery;
means for conducting energy extending through the means for housing, wherein the means for conducting energy includes lead; and
means for covering the means for conducting energy such that no exposed lead is exterior to the means for housing, wherein the means for covering is selected from the group consisting of tin, zinc, brass, copper, stainless steel, nickel, and alloys thereof.

14. The lead acid battery of claim 13 , wherein the means for covering further includes a coating of the selected material.

15. The lead acid battery of claim 14 , further comprising:
second means for conducting energy extending through the means for housing; and
second means for covering the second means for conducting energy, wherein the second means for covering is of a second material different from the selected material of the means for covering.

16. The lead acid battery of claim 4 , wherein the coating is selected from the group consisting of tin, zinc, brass, copper, stainless steel, nickel, and alloys thereof.

17. The lead acid battery of claim 9 , wherein the first coating is selected from the group consisting of tin, zinc, brass, copper, stainless steel, nickel, and alloys thereof.
