What is the initial voltage of a car battery?

The initial voltage of a car battery is typically around 12.6 volts, but it can vary slightly depending on the battery's state of charge and the ambient temperature. When a car battery is fully charged, its voltage will be closer to 12.7 volts, while a discharged battery may have a voltage as low as 12.0 volts or even lower. It's important to note that the voltage of a car battery can also be affected by other factors, such as the electrical load being placed on the battery and the health of the battery's cells.
