1. A method of testing a storage battery comprising:
- connecting a battery test device to the storage battery;
obtaining, via an input of the battery test device, identification information for an operator carrying out the battery test;
obtaining, via the input of the battery test device, test condition information related to the battery;
obtaining battery measurement values by performing a step in a battery test on the storage battery with the battery test device;
digitizing the battery measurement values with the battery test device;
determining, using a microprocessor in the battery test device, a condition of the battery as a function of the digitized battery measurement values and the test condition information;
digitally combining the operator identification information, the test condition information, the digitized battery measurement values and the condition of the battery to form an encrypted code, the encrypted code having properties such that the operator identification information, the digitized battery measurement values and the condition of the battery are subsequently recoverable from the encrypted code and the battery test subsequently verifiable through comparing the measurement values to the condition of the battery to identify operator falsification of the battery test; and
transmitting the encrypted code that combines the operator identification information, the test condition information, the digitized battery measurement values and the condition of the battery, across a wireless communication medium to an external receiver.
