In modern cars, the central control system is the core part of the vehicle's electronic control, responsible for managing functions such as in-vehicle entertainment, navigation, air conditioning, and window control. In order to ensure that these systems can still save key data (such as time, user settings, fault codes, etc.) after the vehicle is turned off, the car central control system usually requires a reliable backup power solution. Button batteries are ideal for car central control systems because of their small size, stability, and long life. Among them, BR2032 is a commonly used button battery model in car central control systems, and is favored for its high temperature resistance, superior storage performance, and wide range of applications.
