How many hours does it take to charge a dead car battery?
1 Answers
If you want to charge a dead battery using the engine, it will take a total of 20 hours. Here is the relevant information: 1. If you intend to charge a dead battery using the engine, take a 12V60Ah battery as an example. The charging method adopts constant voltage and current limiting mode, with 14.8V constant voltage and 15A current limiting for 16 hours, followed by 3A constant current charging for 4 hours, totaling 20 hours. The required charging time is relatively long. 2. If the battery dies while driving, you can pull over before the vehicle becomes immobile and seek help from other drivers to charge your car battery by jump-starting with jumper cables between the two vehicles. Alternatively, you can call a tow truck to transport the car to the nearest repair shop for battery charging.
