Single-use battery Panasonic CR 1220
The Panasonic CR 1220 is a single-use lithium coin cell with a nominal voltage of 3V and a compact diameter of approximately 12.5 mm and height of 2 mm. Designed for small electronic devices, this battery delivers stable voltage and long shelf life typical of lithium chemistry. Its low weight and thin profile make it suitable for compact assemblies where space is limited.
The CR 1220 offers consistent 3V output throughout most of its service life, low self-discharge for long storage, and reliable performance in low-to-moderate drain applications. Its slim design fits shallow battery compartments and small electronic housings, while lithium chemistry provides wider operating temperature range and longer shelf life compared with alkaline alternatives.
Install the battery with the correct polarity indicated in the device (positive side usually marked with "+"). Avoid forcing the cell into the compartment; if it does not fit easily, recheck model compatibility. Replace with the same type of coin cell to ensure correct voltage and fit. Dispose of used batteries according to local regulations for lithium batteries.
Store unused batteries in a cool, dry place away from metal objects. Do not recharge, disassemble, heat above recommended temperatures, or expose to fire. Keep out of reach of children; coin cells present a swallowing hazard and require immediate medical attention if ingested.
