How to use

Identify the battery compartment in your device and verify it accepts CR2025 cells. Observe polarity markings and insert the cell with the correct orientation, typically positive (+) side facing up, until it seats securely. Ensure the device is switched off or isolated from power when replacing the battery. Do not attempt to recharge or disassemble the cell; dispose of used batteries according to local regulations or recycling programs.

Usage recommendations

Store batteries in a cool, dry place away from direct sunlight and metal objects to avoid short circuits. Replace batteries in matched pairs where applicable and check device contacts for corrosion before installing a new cell. Keep out of reach of children and seek immediate medical attention if a battery is swallowed.
