Abstract

A lead acid battery has a housing having a plurality of adjacently positioned battery plate receiving compartments. A cell of battery plates is positioned in each battery plate receiving compartment. Each cell has a plurality of positive plates, each having a positive lug, and a plurality of negative plates interleaved with the positive plates, each having a negative lug. A mold positioned on a top edge of each group of battery plates, and has two strap molding wells, each having a lead receiving space, a well base, and a plurality of lug receiving openings positioned in the well base. The positive lugs of the cell extend through the lug receiving openings in one of the strap molding wells, and the negative lugs of the cell extend through the lug receiving openings in the other strap molding well.

Claims (30)

1. A lead acid battery comprising:

a housing having

an open first end, and

a plurality of adjacently positioned battery plate receiving compartments;

a cell of battery plates positioned in each battery plate receiving compartment, each cell having

a plurality of positive plates, each having a positive lug, and

a plurality of negative plates interleaved with the positive plates, each having a negative lug;

a mold positioned on a top edge of each cell of battery plates, and having

two strap molding wells, each having

a lead receiving space,

a well base, and

a plurality of lug receiving openings positioned in the well base, the positive lugs of the cell extending through the lug receiving openings in one of the strap molding wells, and the negative lugs of the cell extending through the lug receiving openings in the other strap molding well, and

a floor extending between the two strap molding wells; and

a cover separate from the molds and positioned over the molds on the first end of the housing, the cover having a plurality of mold well receiving openings, two mold well receiving openings positioned over each battery plate receiving compartment.

2. The lead acid battery of claim 1 , wherein the positive lugs and the negative lugs extend into the lead receiving space of each strap molding well.

3. The lead acid battery of claim 2 , wherein the two strap molding wells of each mold partially extend into the two mold well receiving openings over each battery plate receiving compartment.

4. The lead acid battery of claim 3 , wherein the cover further includes rectangular cutouts extending as a channel between two strap molding wells of two separate molds positioned on cells in adjacent battery plate receiving compartments.

5. The lead acid battery of claim 4 , further comprising a lead strap positioned in each cutout.

6. The lead acid battery of claim 5 , wherein the lead strap extends from each cutout into the lead receiving spaces of two strap molding wells positioned on cells in adjacent battery plate receiving compartments.

7. The lead acid battery of claim 6 , wherein the lead strap is integrally connected with the lugs in each of the two strap molding wells position on cells in adjacent battery plate receiving compartments.

8. The lead acid battery of claim 5 , further comprising an epoxy seal filled around each lead strap.

9. The lead acid battery of claim 7 , further comprising a first terminal post having first terminal post feet positioned in one strap molding well.

10. The lead acid battery of claim 9 , wherein the first terminal post feet are interleaved into the lugs positioned in the strap molding well.

11. The lead acid battery of claim 10 , wherein the first terminal post feet are integrally connected to both the lugs and the lead strap.

12. The lead acid battery of claim 11 , further comprising a second terminal post having second terminal post feet positioned in another strap molding well, the second terminal post feet being interleaved between the lugs positioned in the other strap molding well and being integrally connected to both the lugs and the lead strap.

13. The lead acid battery of claim 12 , wherein the cover further includes at least two terminal bushings.

14. The lead acid battery of claim 13 , further comprising a manifold positioned on the cover.

15. The lead acid battery of claim 14 , wherein the manifold is positioned over the lead straps and sealed to the cover.

16. The lead acid battery of claim 1 , wherein the floor has an electrolyte access hole.

17. The lead acid battery of claim 16 , wherein the cover has corresponding electrolyte filling holes positioned over the electrolyte access hole.
