Abstract:
An apparatus for testing a storage battery, comprising:battery test circuitry configured to perform a battery test on the storage battery, the battery test circuitry responsively providing a test result output related to a condition of the storage battery;a current date memory configured to store a current date;a test date memory configured to store test count dates indicative of dates on which a battery test was performed; andtest counter circuitry coupled to the battery test circuitry and test date memory, the test counter circuitry configured to store a current date in the test date memory in response to an occurrence of a battery test performed by the battery test circuitry the stored current date indicative of a date on which a battery test was performed, the test counter circuitry further configured to determine a number of battery tests performed during a test period of at least one day as a function of the stored test dates in the test date memory.
