How to Test a Car Battery with a Multimeter
When your car doesn’t start, often a low or dead battery is the culprit. Unfortunately, most vehicle owners do not check their battery until it fails. As preventative maintenance, the suggested best practice is to conduct a car battery voltage test regularly – at least twice per year – using a multimeter.
A multimeter is an electronic measuring instrument that is used to gauge volts, amps, and resistance from an electrical source. The most common automotive application for a multimeter is to test the strength of a car battery. When used properly, it will provide voltage information to a high degree of accuracy on a digital readout. Understanding the data provided is vital in determining whether the battery is strong and healthy or should be replaced.
