Abstract
An electronic battery tester for testing a storage battery include storage battery test circuitry configured to receive power through a power input. An internal battery is configured to provide power to the power input of the storage battery test circuitry. A switch is provided to selectively couple the storage battery test circuitry to the internal battery such that the internal battery can be tested.
Claims56
An electronic battery tester for testing a storage battery, comprising:
- storage battery test circuitry having test connections configured to test a battery, the storage battery test circuitry configured to receive power through a power input;
- an internal battery configured to provide power to the power input of the storage battery test circuitry;
- and
- a switch configured to selectively couple test connections of the storage battery test circuitry to the internal battery to thereby configure the test circuitry to test the internal battery.
