Do I need to go to a 4S shop to replace the car battery?

You don't need to go to a 4S shop to replace the car battery. You can replace it yourself or go to an auto repair shop. The battery should be replaced every 2 to 3 years. The warranty period for a new car is about 3 years or 100,000 kilometers, and the life of a car battery is about 3 years. After this period, the owner should pay attention to the maintenance of the battery and replace it in time if necessary to avoid danger. The functions of the battery are: 1. When starting the engine, the battery supplies power to the starting system, ignition system and electronic fuel injection system; 2. When the engine stops running or is at low idle speed, it supplies power to the car's electrical equipment; 3. When the generator's output is insufficient, it can assist in supplying power to the electrical equipment; 4. It can mitigate the impact voltage in the electrical system and protect the electronic equipment on the car.
