How to use

Replace depleted cells with new CR2032 batteries observing polarity markings: the flat side marked with the positive sign (+) should face the corresponding contact in the device. Ensure the device is powered off during replacement when possible. Handle cells individually to avoid short circuits and install them in clean, dry battery compartments. Dispose of used lithium button cells according to local recycling and hazardous-waste regulations.

Usage recommendations

Store unused cells in their original packaging in a cool, dry place away from metal objects and direct sunlight. Keep batteries out of reach of children and pets. For devices with irregular power draw or long standby periods, check device manufacturer recommendations for cell replacement intervals to maintain reliable operation.
