It takes about 10 hours of charging for a car with a dead to return to normal. Battery charging voltage: The car charging voltage is 12V. During the charging process, the charging voltage is mostly between 13.5-14.5V. When charged on the vehicle by the rectifier, it will not exceed 15V. If using a battery charger, the charging voltage is generally 14V. Battery charging current: During the car charging process, the charging current should not be too large. It is recommended that car owners avoid using fast charging. When charging, use a current that is half the size of the rated charging current, and the rated charging time needs to be doubled.
