How to use

Replace the depleted battery with a new CR2032 cell, observing device-specific polarity markings (+ and −) and the correct orientation in the battery compartment. Use gentle pressure to seat the cell without forcing or deforming the device case. After replacement, verify device operation and correct date/time settings where applicable. Dispose of the used battery according to local regulations for lithium cells or take it to a designated recycling point.

Usage recommendations

Store batteries in a cool, dry place and avoid exposing them to high temperatures or direct sunlight. Keep out of reach of children and pets; button cells present a swallowing hazard. Remove the battery from devices that will be unused for long periods to prevent potential leakage. Follow device manufacturer guidance for battery replacement intervals and recycling options.
