Abstract

A method and apparatus for auditing condition of a storage battery performs a battery test on the storage battery to obtain a test result. Subjective information pertaining to the battery is obtained. An audit code is generated based on the battery test result and the subjective information.

Claims

1. A method of monitoring the condition of a storage battery, comprising:

performing a battery test on the storage battery and obtaining a test result;

obtaining subjective information pertaining to the battery; and

generating an audit code based on the test result and the subjective information.

2. The method of claim 1 wherein obtaining subjective information comprises obtaining observation data pertaining to a problem with the battery and generating the audit code based on the observation data.

3. The method of claim 2 wherein the problem relates to a vehicle containing the battery.

4. The method of claim 2 wherein the problem relates to a physical condition of the battery.

5. The method of claim 2 wherein the problem is observed by a technician.

6. The method of claim 2 wherein the problem is observed by a customer using the battery.

7. The method of claim 1 wherein obtaining subjective information comprises obtaining an indication of customer accommodation and generating the audit code based on the indication.

8. The method of claim 1 and further comprising obtaining battery test information related to conditions of the battery test and generating the audit code based on the battery test information.

9. The method of claim 8 wherein the battery test information includes a name of the operator performing the battery test.

10. The method of claim 8 wherein the battery test information includes a location of the dealer performing the battery test.

11. The method of claim 8 wherein the battery test information includes information related to a vehicle containing the battery.

12. The method of claim 8 wherein the battery test information includes obtaining temperature information.

13. The method of claim 8 wherein the battery test information includes rated battery Cold Cranking Amps (CCA).

14. The method of claim 1 wherein performing a battery test includes determining battery conductance.

15. The method of claim 1 wherein performing a test includes applying an electrical load to the battery.

16. The method of claim 1 wherein the audit code comprises an alpha numeric code.

17. The method of claim 1 wherein the audit code is encrypted.

18. The method of claim 1 including placing the audit code on the battery.

19. The method of claim 1 and further comprising obtaining battery test information and wherein obtaining subjective information comprises obtaining observation data and an indication of customer accommodation, and generating the audit code based on the battery test information.

20. An electronic battery tester configured to generate the audit code in accordance with the method of claim 1.

21. An apparatus for monitoring the condition of a storage battery, comprising:

battery test circuitry for performing a battery test on the storage battery and providing a battery test result;

input circuitry receiving subjective information pertaining to the battery;

calculation circuitry coupled to the battery test circuitry and the input circuitry and generating an audit code based on the battery test result and the subjective information.

22. The apparatus of claim 21 wherein the subjective information comprises observation data pertaining to a problem with the battery and the calculation circuitry generates the audit code based on the observation data.

23. The apparatus of claim 22 wherein the problem relates to a vehicle containing the battery.

24. The apparatus of claim 22 wherein the problem relates to a physical condition of the battery.

25. The apparatus of claim 22 wherein the problem is observed by a technician.

26. The apparatus of claim 22 wherein the problem is observed by a customer using the battery.

27. The apparatus of claim 21 wherein the subjective information comprises an indication of customer accommodation and the calculation circuitry generates the audit code based on the indication.

28. The apparatus of claim 21 wherein the input circuitry further receives battery test information related to conditions of the battery test and the calculation circuitry generates the audit code based on the battery test information.

29. The apparatus of claim 28 wherein the battery test information includes a name of the operator performing the battery test.

30. The apparatus of claim 28 wherein the battery test information includes a location of the dealer performing the battery test.

31. The apparatus of claim 28 wherein the battery test information includes information related to a vehicle containing the battery.

32. The apparatus of claim 28 wherein the battery test information includes temperature information.

33. The apparatus of claim 28 wherein the battery test information includes rated battery Cold Cranking Amps (CCA).

34. The apparatus of claim 21 wherein the battery test circuitry includes means for determining battery conductance.

35. The apparatus of claim 21 wherein the battery test circuitry includes means for applying an electrical load to the battery.
