What is the normal voltage range for a car battery?

[MacGia]

Under normal circumstances, the voltage of a car battery before starting should be between 11.8V and 12.8V, while after starting, it should range from 13.2V to 14.8V. As long as the voltage during startup does not fall below 11V, it is considered normal. Here are some key points about car batteries: 1. Function: The battery plays a crucial role in the operation of a car. If the battery fails to supply power properly, the engine will encounter issues. Car owners should regularly inspect their batteries—weekly in summer and biweekly in winter. 2. Factors affecting battery lifespan: Vehicle condition, road conditions, and driving habits. Good driving habits can extend the battery's service life.
