How many volts below the car battery will not start?What is the normal voltage of the car battery

Generally speaking, if the car battery is lower than 11 volts, it will not start. When the voltage of the battery is between 11 and 12 volts, it will be more difficult to start the vehicle. The normal value of the battery voltage is 12 to 15 volts. When the vehicle starts After that, the normal value of the battery voltage is between 13.4 and 14.8 volts.

The impact of the car battery voltage being too high or too low

1. When the voltage of the battery is too high, it will be difficult to start the vehicle. If it is serious, it will not start at all. You need to use a charger to charge the battery;

2. When the voltage of the battery is too high, the battery will be seriously damaged, which will seriously affect the service life of the battery;
