Everyday power for small devices

This Sony CR2032 lithium coin cell delivers 3 V and 220 mAh for wrist watches, calculators, key fobs and motherboard CMOS memory. The 20 mm diameter and 3.2 mm height fit the standard CR2032 holder found in countless consumer electronics. It arrives new and ready for immediate installation.

Voltage and capacity match the device

The single specification that decides fit is the 3 V output combined with a 220 mAh rating. A device designed for a CR2032 expects this exact voltage and energy budget; substituting a different chemistry or capacity will cause incorrect operation or reduced runtime.

Stable output with minimal self-discharge

Lithium chemistry provides a flat discharge curve so voltage remains steady through most of the cell’s life. Leakage resistance is excellent and the battery retains charge for years in storage, making it reliable for backup roles such as real-time clocks or medical monitors. No heat or noise is produced in normal use.
