How many kilometers does it take to fully charge the battery?

[MacRose]

It takes about 300 to 500 kilometers to fully charge the battery. The functions of the battery are: 1. To supply power to the starting system, ignition system, and electronic fuel injection system when starting the engine; 2. To supply power to the car's electrical equipment when the engine is stopped or idling at low speed; 3. To assist in supplying power to the electrical equipment when the generator's output is insufficient; 4. To mitigate impact voltage in the electrical system and protect the electronic equipment in the car; 5. To store excess electricity generated by the generator. The maintenance methods for the battery are: 1. Start the car regularly to charge the battery; 2. Add distilled water or special replenishing fluid when the electrolyte is insufficient; 3. Frequently check whether the small holes on the battery cover are ventilated during daily driving; 4. Check whether the positive and negative terminals of the battery are oxidized; 5. Check whether any part of the circuit is aged or short-circuited; 6. Turn off electrical equipment when leaving the car.
