Understanding the Car Battery
Before we dive into the voltage requirements, let’s first understand the role of the car battery. The car battery provides the electrical energy necessary to start the engine and power the vehicle’s electrical systems. It is essential for the proper functioning of your car.

Minimum Voltage to Start a Car
The minimum voltage required to start a car is typically around 12 volts. This is the standard voltage for most car batteries. When you turn the key in the ignition, the starter motor draws a high current from the battery. To provide the required power, the battery needs to maintain a voltage of at least 12 volts.
Testing the Voltage of a Car Battery
If you are unsure about the voltage of your car battery, you can easily test it using a multimeter. Follow these simple steps:
- Set your multimeter to the DC voltage setting.
- Connect the positive (red) lead to the positive terminal of the battery and the negative (black) lead to the negative terminal.
- Read the voltage displayed on the multimeter.
If the voltage reads below 12 volts, it may be an indication that your battery is not fully charged or needs to be replaced.
Jump Starting a Car
If your car battery’s voltage is too low to start the engine, you can jump start it using another vehicle’s battery. The voltage of the jump-starting battery should be the same as a normal car battery, typically around 12 volts. Connecting the two batteries allows the higher voltage from the jump-starting battery to transfer to the low-voltage battery, providing enough power to start the engine.
