12.2v is enough to start the car.

It’s a 12v battery after all, it’s just voltage settling after being at ~14v when driving..

What is the minimum voltage needed to start a car?

Fully charged automotive batteries should measure at 12.6 volts or above. When the engine is running, this measurement should be 13.7 to 14.7 volts. If you don’t have a multimeter to tell you the voltage of your battery, you can do a test of your electrical system by starting the car and turning on the headlights.

Is 11.8 volts enough to start a car?

Is 12.3 volts enough to start a car?

However, what is the minimum voltage to start a car? There is no exact answer to the question. In the standard state, a fully charged battery should show a 12.6-12.7V.

At what voltage is a 12v battery dead?

For a 12 volt, leadacid battery, the voltage measured between these two points should be between 11 and 13 volts. The closer the voltage is to 13 volts, the closer the battery is to being fully charged. The closer the voltage is to 11 volts, the closer the battery is to being “dead”.

What voltage is too low for car battery?

Check the reading to see the current voltage of your car battery. Anything lower than 12.2 volts, and it’s identified as a bad battery.
