How to use

Install the battery observing correct polarity markings in the device battery compartment. Ensure contacts are clean and free from corrosion before insertion. Replace with a new battery of the same type to maintain device performance and correct voltage. Dispose of used batteries according to local regulations for lithium primary cells; do not attempt to recharge, puncture, or incinerate the cell.

Recommendations

Store unused batteries in a cool, dry place and avoid prolonged exposure to high temperatures. For devices requiring long-term memory backup or continuous sensor operation, check the battery and device periodically and replace the cell before voltage drops below the device's minimum operating threshold.
