How do battery load testers work?

Small and light portable battery load testers work very similarly to carbon pile battery testers, by measuring a battery’s response to a large current draw, but these do it for a short amount of time. Some hand-held battery load testers also feature more advanced mathematical analysis of the battery’s response to the sudden load.

How do you test a battery with a hand-held load tester?

Connect the hand-held load tester leads to battery (observing electrical polarities). Turn on tester, and input battery specifications (e.g. size, capacity, cold cranking amps). Press the test button to perform the test. Read the results from the tester’s screen or print-out.

How do you test a battery?

Observe how much the battery voltage drops under load. Carbon pile battery testers are the simplest type, are intuitive, easy-to-use, and can be very effective. The carbon pile is a large (low-value) electrical resistor, and the ‘tester’ works by measuring how much current the battery is able to discharge through the large resistor.

How do I use a battery tester?

You will need to insert the battery into the tester, ensuring the positive and negative contacts on both the battery and the tester match up correctly. Make sure that the battery is firmly secured in place before you take the reading.

How does a battery test work?

If a battery has a charge, the ink heats up as the current passes through it. A higher temperature indicates the battery has more current. The gauge from the battery tester usually changes colour based on the temperature.
