How to use

Replace the depleted cell with a new Panasonic CR2450 by opening the device battery compartment according to the device manufacturer’s instructions and inserting the cell with correct polarity. Ensure the positive (+) and negative (−) markings align with the device contacts. After replacement, secure the compartment and test device operation. Dispose of the used cell in accordance with local regulations for battery recycling and hazardous waste.

Usage recommendations

Store unused cells in a cool, dry place and avoid exposure to high temperatures or direct sunlight. Do not attempt to recharge, disassemble, short-circuit, or expose the cell to fire. For optimal device performance, check device polarity before insertion and replace batteries in matched sets when multiple cells are used together.
