What is the voltage of a fully charged car battery?
1 Answers
A fully charged battery should have a voltage between 12.5V and 13V. The battery is a crucial component of a car; without it, the car cannot operate normally. When the engine is not started, the battery supplies power to all electronic devices in the car and is also responsible for starting the engine. After the car is started, the voltage should generally be between 13.4V and 14.8V. If the voltage is below 13.4V, the battery may not be charging properly; please check the engine or other electrical loads. If the voltage exceeds 14.8V, it may damage the battery; please check the engine stabilizer. When the car's engine is not running, the battery voltage should be between 12.2V and 12.8V. If the voltage drops below 11.6V, it may be difficult to start the car; please turn off other electrical devices as soon as possible. When the battery voltage is below 10V, the car usually cannot be started. Battery maintenance: When the battery is not in use, it should be charged once a month to extend its lifespan. To prevent damage, regular inspections are necessary. Avoid sudden high-current discharges. Typically, car batteries are charged overnight, with an average charging time of about 8 hours. Electric vehicles must not be exposed to direct sunlight.
