The reasons for the 'thud' sound when starting the car after a long period of parking include ignition delay and insufficient battery power. Below are some relevant details about the battery: 1. Lifespan: The normal lifespan of a car battery is generally around two years; 2. Maintenance: With proper maintenance, it can be extended, and the best can last about four years. Signs of a weak car battery: The car is difficult to start after being parked for two days, and the car becomes noticeably heavier when driving with the air conditioning on. 3. Precautions for car batteries: Modern car batteries have a protection function that retains the minimum power required for ignition. If you turn the key without starting the engine and listen to music or turn on the lights, it can last for about an hour or so.
