MnO2 coin cell with a R2032 case
The CR2032 is a lithium coin cell battery widely used in low-power electronic devices. 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.
