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. | |||
