Is a car battery voltage of 14.4v normal?
1 Answers
A car battery voltage of 14.4v is abnormal. Under no-load conditions, the normal voltage of a car battery is around 13v, and the load voltage should normally not be lower than 11v. If the voltage is below this level, it may cause difficulty in starting the vehicle. After starting, as the alternator begins generating electricity, the car battery voltage should normally be between 13.5v and 14.5v. Both excessively high or low battery voltage can have certain impacts. It is advisable to regularly check the battery's condition. Once the battery voltage drops below 10.8V, it should be charged promptly. If the battery voltage is too low, the car may experience difficulty starting or even fail to start. Conversely, if the battery voltage is too high, it can damage the battery. The battery can be charged by the alternator while the car is running. If the car is parked for an extended period, it can easily lead to battery power loss, resulting in the car failing to start. Therefore, during long-term parking, it is best to start the vehicle at least once a week. The alternator will charge the battery, typically requiring idling for more than 5 minutes. Additionally, when parking for an extended period, it is recommended to disconnect the battery's negative terminal, as the battery will naturally discharge even when not in use. This measure helps prevent the vehicle's battery from being completely drained.
