What is the voltage of the car battery in volts

How many volts is the car battery voltage? This is an important issue related to vehicle starting, and different battery voltages will have different effects on vehicle performance.

In general, most car batteries are 12V or 24V. For a vehicle powered by a single-cylinder diesel engine and two batteries with the same capacity in parallel, the battery voltage of 24V is usually used; while the battery voltage of a gasoline engine car is usually 12V. In addition, when judging whether the battery is in normal working condition, we can refer to it according to the standard range of the battery voltage.

The standard range of car battery voltage is 11.8-12.8V. If the battery voltage is less than 10.8V, it means that the battery is in a state of depletion. When the battery voltage is lower than the normal range, it may cause difficulty in starting the vehicle because the starter cannot get enough current. At this time, we can turn off the electrical equipment on the vehicle, let the vehicle run at idle speed, or drive on the road for about half an hour, so that the generator can replenish the battery.

The car battery is one of the indispensable parts of the car. It not only needs to provide sufficient power to start the engine, but also needs to provide power for the electrical equipment on the vehicle. Therefore, we need to maintain and maintain the battery regularly, so that the working condition of the battery can be at a normal level and the service life can be extended to a certain extent.
