Does idling the car charge the battery?

[MaggieLee]

Yes, it can charge the battery. There are four methods for battery maintenance: 1. Parking duration: Avoid leaving the car parked in an open-air parking lot for extended periods. If long-term parking is necessary, remove the battery to prevent freezing damage. 2. Time intervals: In winter, car engines are harder to start. Each attempt should not exceed 5 seconds, with at least 15 seconds between subsequent attempts. If the engine fails to start after multiple attempts, check the circuit, ignition coil, or fuel system for issues. 3. Regular charging: The battery needs frequent charging. If unused for long periods, it will gradually self-discharge and eventually become unusable. Therefore, start the car periodically to charge the battery. 4. Cleaning: Clean the battery terminals regularly and apply specialized grease to protect the wiring harness. Also, frequently inspect the battery components and connecting wires.
