   Battery tester. A battery tester is an electronic device intended for testing the state of an electric battery, going from a simple device for testing the charge actually present in the cells and/or its voltage output, to a more comprehensive testing of the battery's condition, namely its capacity for accumulating charge and any possible flaws affecting the battery's performance and security.

3. Battery simulator - Wikipedia

   en.wikipedia.org/wiki/Battery_simulator

   If the battery simulator has a current limit feature and if the current exceeds the maximum set value, the simulator automatically increases the voltage to limit the current [3] The advantage of using a battery simulator is its ability to freely set the emulated battery voltage to any value in order to test the charger.

4. Solenoid voltmeter - Wikipedia

   en.wikipedia.org/wiki/Solenoid_voltmeter

   When testing power supply circuits, a high-impedance connection (that is, a nearly open-circuit fault such as a burned switch contact or wire joint) in the power path might still allow enough voltage/current through to register on a high-impedance digital voltmeter, but it probably can't actuate the solenoid voltmeter. For use with high ...

6. Electrical safety testing - Wikipedia

   en.wikipedia.org/wiki/Electrical_safety_testing

   To do this test, you need to have an insulation resistance tester, which may be a small hand held battery powered device, up to a larger luggage sized tool able to achieve higher test voltages. Variables to choose before starting an electrical resistance test is the test voltage, test duration, and test points.
