Why do I need a car starter instead of buying a new car battery
1. Car battery replacement needs to go to a professional car repair shop
2. The function of the car battery is normal, but it cannot be started due to an accident or cold weather
3. If the car breaks down when going out or traveling, you need to pay expensive rescue fees and send it to the car repair shop
