How Many Volts Does It Take to Start a Car?

A car battery is a 12-volt lead-acid system that provides power to the car''s starter and voltage regulator to work together. To start a car, you need to have enough voltage in your battery. Generally, a car needs at least 9 volts of electricity to start, although some with more advanced electrical systems may require up to 11 volts. The voltage range of a car battery is
