An apparatus for testing a storage battery in an automotive vehicle includes a controllable electrical load configured to electrically couple to the storage battery of the vehicle. A current sensor is configured to electrically connect to a terminal of the battery and measure flow of current through the battery. A controller is arranged to apply an electrical load to the battery using the controllable load and adjust the electrical load while monitoring the electrical current sensed by the current sensor to determine a charge current applied to the battery by an alternator of the vehicle and further configured to perform a test on the battery. A method for testing a storage battery in an automotive vehicle includes connecting a controllable electrical load to the storage battery, connecting a current sensor to a connection to a terminal of the battery, applying an electrical load to the battery using the controllable electrical load, adjusting the electrical load while monitoring an output from the current sensor to determine a charge current applied to the battery by an alternator of the vehicle, and performing a test on the battery.
