Abstract
An electronic battery tester for testing a storage battery including electrical connectors configured to couple to the storage battery. Measurement circuitry is coupled to the electrical connectors and a display is configured to display information to an operator. A manual input is configured to receive an input from a user. A microprocessor is coupled to the measurement circuitry and is configured to perform a battery test on the storage battery as a function of a battery parameter measured with the measurement circuitry. The microprocessor is configured to display characters and receive a character select input from the manual input which identifies one character of a plurality of characters displayed on the display. In another aspect, a forcing function is coupled to the battery and has first and second selectable frequencies. The microprocessor is configured to select between the first frequency and the second frequency.
