Abstract

Batteries for boats and vehicles require a CRA (cranking) battery 23 and an AUX (auxiliaries) battery 22 to ensure a start. The preferred version has an AUX battery made of parallel plates and a CRA battery made of parallel plates lying in a monobloc case in face to face positions. Each battery has a pair of CRA terminals 20, 30 for the electric starter and a pair of AUX terminals 19, 31 for the AUX loads of the vehicle and the alternator. The AUX and CRA negative are joinable by a link or a switch 41 so that a single earth connection is made to the vehicle. Alternatives show the AUX and CRA batteries side by side, at 90 degrees, providing 24 v or 36 v with a 12 v tap; a CRA battery with two AUX batteries one 51 for constant voltage equipment. Advant-ageous disposition of terminals simplifies connections to vehicle wiring and to a like battery.

Claims

1. A 4-pole battery for vehicle use comprising a CRA battery with a positive pole for connection to a starter motor, an AUX battery with a positive pole for connection to auxiliaries, the CRA battery having plates lying face to face along a horizontal plane of the battery, the AUX battery having deep cycle plates lying face to face along a horizontal plane of the battery, both AUX and CRA batteries being of different construction and accommodated in a case with side by side compartments, the CRA battery having a negative pole and the AUX battery having a negative pole.

2. A 4-pole battery as in claim 1 wherein the volume of the AUX battery is in the range of 35-45% of the volume of the battery.

3. A 4-pole battery as in claim 1 wherein the case is a monobloc moulding.

4. A 4-pole battery as in claim 1 wherein the battery has a set of terminals for the CRA battery and a separate set of terminals for the AUX battery.

5. A 4-pole battery as in claim 1 and a like battery connected thereto in series to give increased voltage.

6. A 4-pole battery as in claim 1 wherein the battery is attached to another battery.

7. A battery as in claim 1 having a monobloc battery case closed by a battery lid housing an AUX battery and a CRA battery yielding 24 v.

8. A battery as in claim 7 wherein the battery has a 12 v tap.

9. A battery as in claim 1 having a monobloc battery case closed by a battery lid housing an AUX battery and a CRA battery yeilding 36 v or more.

10. A multipole battery as in claim 1 wherein the negative poles are linked by a switch.

11. A multipole battery as in claim 1 wherein the negative poles are connected by a conductor link embedded in a lid on the case.

12. A multipole battery comprising a CRA battery intended for connection to a starter motor and an AUX battery intended for connection to auxiliary electrical loads, the CRA battery and the AUX battery being of different construction and each capable of providing a current different from the other, the CRA battery containing parallel plates and the AUX battery containing parallel plates, the AUX and CRA batteries lying face to face along a horizontal plane of the battery in a single battery case, wherein the CRA battery and the AUX battery each have independent positive and negative terminals.

13. A battery as in claim 12 wherein the plates are rectangular in shape.

14. A battery as in claim 12 wherein the battery is a lead acid battery.

15. A battery as in claim 12 wherein the CRA battery and the AUX battery each have a terminal cell and at least one terminal connected to the terminal cell by a conductor.

16. A battery as in claim 15 wherein a provision is provided for linking like terminal together within a battery lid.

17. A battery as in claim 15 wherein at least one terminal is connected to the terminal cell by a conductor.

18. A battery as in claim 12 wherein the battery contains a terminal cell and a battery lid supports both a terminal and an embedded conductor, whereby the terminal is placed remotely from the terminal cell.

19. A battery as in claim 18 wherein the CRA battery and the AUX battery have a communal terminal.

20. A battery as in claim 18 having inter-cell connections wherein all the connections, apart from those used to mutually connect the terminal cells, are on one axis in the CRA battery and one axis in the AUX battery.

21. A battery as in claim 18 wherein the terminal is mounted remotely from the terminal cell.

22. A battery as in claim 18 wherein part of the conductor is moulded into the battery lid.

23. A battery as in claim 18 wherein the lid is a polymeric moulding containing an embedded conductor located in the body of the lid by spacing means incorporated into the polymer of the lid during moulding.

24. A battery as in claim 18 wherein the lid is a polymeric moulding containing an embedded conductor located in the body of the lid by spacing means which are insulative.

25. A battery as in claim 12 having a CRA battery, an AUX battery for electrical auxiliaries and a second AUX battery providing a different current from the first AUX battery.

26. A battery as in claim 25 wherein the second AUX battery provides current for loads requiring constant current.

27. A battery as in claim 18, wherein the embedded conductor is in the form of a link with two holes for bolting onto a supplemental threaded post from the AUX and CRA terminals.

28. A battery as in claim 18, wherein part of the conductor is moulded into the battery lid.

29. A battery as in claim 18, wherein the conductor primarily consists of either soft or hard drawn copper strip.

30. A battery as in claim 29, wherein the copper strip is coated with either tin or a tin based solder.

31. A battery as in claim 18, wherein the conductor is made of or coated with aluminum or silver.

32. A battery as in claim 18, wherein the conductor is provided with means for mechanical stabilization thereof in the lid of the battery.

33. A battery as in claim 12, wherein the CRA battery is larger than the AUX battery.
