The first pair and second pair of connectors forming Kelvin connections to the battery. A microprocessor is configured to selectively charge the battery and measure a dynamic parameter of the battery as a function of an AC signal applied to the battery.

Method and apparatus for charging a battery

An apparatus for testing a storage battery includes battery test circuitry configured to perform a battery test on the storage battery. The battery test circuitry responsively provides a test result output related to a condition of the storage battery. A test count memory configured to store a test count and test count circuitry is configured to maintain a test count in response to an occurrence of a battery test performed by the battery test circuitry.
