How to use

Install the battery with the correct polarity, typically with the positive (+) side facing up or as indicated by the device markings. Before replacing a battery, switch the device off if possible and use a non-metallic tool or clean, dry hands to avoid shorting the cell. After installation, verify device operation and dispose of the used battery according to local regulations for single-use lithium cells.

Recommendations

Store unused batteries in a cool, dry place away from direct heat and metal objects. Do not recharge, disassemble or expose to fire. Keep out of reach of children; if swallowed, seek medical help immediately. For devices requiring continuous power or high-drain operation, consult device specifications to confirm suitability of a CR2032 single-use lithium cell.
