Introduction
A CMOS battery, also known as a coin cell or button cell battery, is a small, round, and typically flat battery used to power the CMOS memory in a device MCU. The CMOS memory is responsible for storing system settings such as date and time.
The CMOS battery ensures that the CMOS memory retains its data even when the device is powered off. If the CMOS fails or loses power, the system may forget its settings causing the device to have issues such as incorrect dates and time settings.
