The CR2032 is a lithium coin cell battery widely used in low-power electronic devices.


== Name ==
The name "CR2032" follows the IEC standard naming convention: "C" denotes a lithium manganese dioxide (Li-MnO₂) chemistry (it is a common misconception that the "C" stands for "coin", but this is incorrect). "R" indicates a "round" or cylindrical shape, and "2032" indicates the battery’s dimensions—20 mm in diameter and 3.2 mm in height.
CR2032 batteries typically provide a nominal voltage of 3 volts and a capacity of around 220 mAh, depending on the manufacturer and discharging conditions.
== Applications ==
CR2032 cells are commonly found in:
* Watches and calculators 
* Motherboard CMOS memory backup 
* Remote keyless entry systems 
* Fitness trackers and heart rate monitors 
* Medical devices such as glucose meters 
* Small Internet of Things (IoT) devices
Due to their reliability and standardized size, CR2032 batteries remain a staple in portable electronics and embedded systems requiring compact, long-lasting power sources.

    Name

    The name "CR2032" follows the IEC standard naming convention: "C" denotes a lithium manganese dioxide (Li-MnO₂) chemistry (it is a common misconception that the "C" stands for "coin", but this is incorrect). "R" indicates a "round" or cylindrical shape, and "2032" indicates the battery’s dimensions—20 mm in diameter and 3.2 mm in height.

    CR2032 batteries typically provide a nominal voltage of 3 volts and a capacity of around 220 mAh, depending on the manufacturer and discharging conditions.

    Applications

    CR2032 cells are commonly found in:

    • Watches and calculators
    • Motherboard CMOS memory backup
    • Remote keyless entry systems
    • Fitness trackers and heart rate monitors
    • Medical devices such as glucose meters
    • Small Internet of Things (IoT) devices

    Due to their reliability and standardized size, CR2032 batteries remain a staple in portable electronics and embedded systems requiring compact, long-lasting power sources.
