Why can car batteries run on low voltage?

Car batteries do not run on low voltage. They typically operate at around 12.6 volts when fully charged and may drop to as low as 11.5 volts when discharged. Below this voltage, the battery may not be able to start the car. Low voltage can be caused by a variety of factors, including:

- A weak battery

- A faulty alternator

- A loose or corroded battery cable

- A high electrical load on the battery

If your car battery is experiencing low voltage, it is important to have it checked by a qualified mechanic to determine the cause and prevent further damage to your vehicle.
