How to use

Before installing the battery, confirm the device specifies CR2025 or compatible coin cell. Open the battery compartment according to the device manufacturer’s instructions; observe polarity markings and insert the battery with the correct orientation to ensure proper contact. Secure the compartment cover and test the device function. Dispose of the used battery according to local regulations for battery recycling and hazardous waste; do not attempt to recharge, puncture or expose the battery to high temperatures.

Recommendations

Store unused batteries in a cool, dry place away from metal objects to avoid short-circuiting. Replace batteries in pairs when a device uses more than one cell and follow device-specific guidance for replacement intervals. Keep out of reach of children and seek immediate medical attention if a battery is swallowed.
