What is the voltage of the battery in a Ford Fiesta?

The voltage of the battery in a Ford Fiesta can vary depending on the specific model and engine type. However, the voltage typically ranges from 12 volts to 14.6 volts. When the ignition is on, the battery voltage can register around 12.0 volts, and after starting the car, it can increase to around 14.6 volts due to the alternator charging the battery. It’s important to note that these voltage values are approximate and can vary depending on various factors.
Please keep in mind that the information provided is based on general knowledge and may not apply to every specific Ford Fiesta model. It’s always recommended to consult the vehicle’s manual or contact a certified Ford dealer for accurate and up-to-date information regarding the battery voltage.
