US Patent 10393815 Voice counting of each battery under test

A method and apparatus for testing batteries uses an audible voice prompt 35, 64 to enunciate the battery label or identifier that will be stored with the battery measurement in memory. Since the battery test technician must pay careful attention to the placement of the probes onto the battery terminal, the use of a voice prompt, rather than a visual prompt, allows the technician to keep his/her eyes on the test probes. If the label enunciated by the voice prompt does not match the label of the battery under test, the label on the tester can be reset to match the battery under test. In particular, a battery tester has a program which displays sequential numbers of battery labels that are stored with each battery's measurement data in memory. The sequence of labels corresponds to the sequential numbers marked on batteries in a string, array or matrix.
