How long should the vehicle be driven after a jump start to fully charge the battery?

[Kyle]

After jump-starting a car, it should be driven normally for more than half an hour to ensure the battery is fully charged. The role of the battery: The battery in a vehicle is a crucial component that powers the electrical devices inside the car. If the battery is dead, not only will the car fail to start, but the electrical devices inside the car will also not function properly. There is a generator next to the engine, which can charge the battery when the car is running. Precautions for jump-starting a car: Connect the positive terminal of one car to the positive terminal of the other, and the negative terminal to the negative terminal. When starting, connect the positive terminal first, and when finishing, disconnect the negative terminal first. If the car fails to start, listen to the sound. If there is only a "clicking" sound, it indicates insufficient power. If there is also the sound of the engine turning, it may be another issue. If the car still fails to start after a long period of jump-starting, check whether the battery power of both cars is the same, and try using a more conductive cable.
