If your car is struggling to start or the electrical systems seem weaker than usual, the battery could be the culprit.
Regularly testing your battery with a multimeter helps you spot problems early before you’re left stranded.
This guide will take you through what a multimeter is and provide a clear, step-by-step process to check your car battery health at home.
How do you test a car battery with a multimeter?
To test a car battery, set your multimeter to DC volts (20V range), connect the red probe to the positive terminal and black to negative, then read the voltage.
A healthy battery should read 12.6–12.8V with the engine off, and 13.8–14.4V when running.
