How Long Does It Take to Charge a Car Battery with a Charger?
1 Answers
Starting battery charging generally takes 15-20 hours to fully charge. More relevant information is as follows: 1. Charging Time: Generally, the larger the battery capacity, the longer the charging time. For example: a 12V48AH battery indicates a voltage of 12V and a capacity of 48AH. Using an external charger with a current of 4.8A, it takes 14 hours to fully charge. 2. Charging Method: When the car is running, the battery is replenished by the generator. However, when the battery is severely depleted, it needs to be recharged promptly. The charging capacity from the car itself is insufficient, so a portable charger must be used to charge the battery. It takes 20 hours to charge a car starting battery.
