Abstract
A battery testing apparatus including battery charger/tester and a controller having battery charge mode and a battery test mode. In the battery charge mode, the controller causes a utility power source to be connected to the battery charger/tester, and the battery charger/tester allows electrical current to flow from the utility power source to the battery. In the battery test mode, the battery charger/tester allows current to flow to the utility power source so as to provide a consistently repeatable power draw from the battery reducing the error in detection of a weakened battery.
