How long should a car be started if it hasn't been driven for a long time?

If a car hasn't been driven for a long time, it should be started for about half an hour. It's best to start the car once a week and let it idle for over 10 minutes, which is beneficial for the car's battery and electrical system. Here is some relevant information about cars that haven't been driven for a long time: 1. Preparation for long-term car storage: The main reason a car won't start after being unused for an extended period is usually a dead battery. Therefore, before storing the car for a long time, ensure the battery is fully charged. If that's not possible, disconnect the negative terminal of the battery to prevent power leakage. 2. Precautions for long-term car maintenance: Even if the car isn't being driven for a long time, make sure there is some fuel in the tank, though it doesn't need to be completely full—about half a tank is sufficient. Most modern cars use plastic fuel tanks, so the fuel won't deteriorate due to long-term storage.
