The automatic start and stop of the engine is to automatically turn off the engine when the vehicle stops temporarily (for example, waiting for a red light) while the vehicle is running. When it is necessary to move on, the system automatically restarts a set of systems of the engine. It can reduce unnecessary fuel consumption, reduce emissions and improve fuel economy. The disadvantage is that repeated use of the starter can easily cause overheating and damage to the starter, which also has a certain impact on the life of the battery.

  The working principle of automatic start-stop is very simple, that is, frequent start-stops are required, especially when driving in urban areas. The automatic start-stop requires rapid charging and discharging. If an ordinary battery cannot be charged and discharged multiple times in a short period of time, the automatic start-stop battery has the function of rapid discharge and charging.

  The battery that supports automatic start and stop has higher performance than ordinary batteries. The battery that supports automatic start and stop must have a stronger storage capacity and be able to charge and discharge quickly. At the same time, the service life must be longer than that of ordinary batteries.

  Based on the above reasons, the price of batteries that support automatic start and stop is often higher than that of ordinary batteries.

  Ordinary batteries do not have these properties. If ordinary batteries are used forcibly instead, the end result may be accelerated shortening of the life of ordinary batteries, or even damage.

  The calibration of the ordinary battery management system is different. The automatic start-stop can accurately distribute the current and voltage, while the ordinary battery does not have these functions. Since automatic start-stop requires frequent high-current and high-voltage output, many people worry about the life of the automatic start-stop battery. In fact, the automatic start-stop battery is dedicated for special vehicles, and there are differences in performance. Therefore, the lifespan of the automatic start-up vehicle battery and the ordinary battery are basically the same.

  Correctly recognize the difference between the automatic start-stop battery and the ordinary battery, then there will be no principled errors when replacing the battery. Some measures are even irreversible, such as causing damage to the vehicle. Automatic start-stop has been widely used at present. In addition to the battery, automatic start-stop also has some attention to details. You must be very familiar with these. If you use it wrong, it may really destroy the car.
