How do you test if a battery is good with a multimeter?
Connect the multimeter to the positive and negative battery terminals. If you don’t have a voltage of around 12.6 volts, you may have a bad battery. Now start the car, and look for a revised voltage over 10. If your voltage drops below 5 when the car is running, it is bad and should be replaced right away.
