ABSTRACT:
The battery tester of the present invention includes a heating element for generating heat in response to current supplied from a battery, and an indicator provided in proximity to the heating element for providing a visual indication of the remaining capacity of the battery in response to the heat generated by the heating element. The heating element has a display portion and first and second connecting portions on either side of the display portion that are selectively coupled to opposite terminals of the battery. The connecting portions of the heating elements have a lower resistivity than the display portion thereby reducing the heat generated at the switch contacts that are pressed by the user to activate the tester.
