2 ημέρες πριν · Next, I touch the red probe to the positive terminal of the battery and the black probe to the negative terminal. A healthy, fully charged car battery should read around 12.6 volts or more. If the reading is below 12.4 volts, the battery might be partially discharged. A reading below 12.0 volts indicates a dead battery.
How to check a car battery with a multimeter The first test with your multimeter will measure DC voltage, indicated with a solid line and a dashed line above a letter V. Set the dial to 20, which will allow you to accurately measure between 0-20 Volts.
Learn how to use a multimeter to test your car battery's voltage and determine if it needs to be replaced. AutoZone provides step-by-step instructions on how to test and interpret the results.
The resting voltage should ideally be no lower than 12.6V. Bear in mind that when a battery goes down to 12.2V it's actually only 50% charged, and below 12V it's classed as discharged. What do I do if the car battery is repeatedly going flat? If the battery is continually going flat, it could be because of a 'parasitic loss'.
