Key Features
The CR2032 Lithium Coin Cell Battery , part number BAT-CR2032 , is a compact 3V battery designed for applications requiring a small, reliable source of continuous power. CR2032 batteries are commonly used in computer motherboards, CMOS memory systems, real-time clocks, calculators, remote controls, and various other electronic devices. The BAT-CR2032 uses lithium coin-cell technology and provides a nominal voltage of 3 volts . Its compact round design makes it suitable for electronic devices where space is limited and a small long-life power source is required. In desktop computers and servers, a CR2032 battery is commonly used to maintain the CMOS/RTC settings when the main system power is disconnected. The battery can help preserve system configuration information such as date, time, and certain firmware settings. A weak or depleted CMOS battery may cause a computer to lose its date and time settings or reset certain BIOS/UEFI configuration information after the system has been powered off. Replacing the battery with a compatible CR2032 cell can help restore normal retention of these settings. The BAT-CR2032 is also useful for
