After jump-starting a car with a dead battery, it should run for more than 1 hour before being turned off. Ensure all electrical devices are switched off before turning off the engine. Here are some methods for car battery maintenance: 1. Turn off lights and audio systems before parking and shutting down the engine; 2. Avoid leaving the air conditioning on when turning off the engine; 3. Drive the car periodically for a certain distance; 4. Regularly clean the battery; 5. Prevent battery discharge; 6. Check the battery every six months; 7. Monitor the battery status indicator promptly. Additional information: If a car battery is left unused for a long time, it will gradually self-discharge and eventually become unusable. Therefore, the car should be started periodically to recharge the battery.
