How to use
Before installation, verify the device manufacturer's recommended cell type and polarity. Use a non-metallic tool or appropriate battery tweezers where possible to avoid shorting the cell. Insert the Maxell SR731SW with the correct orientation, ensuring a secure fit in the battery compartment and that contacts are clean and free of corrosion. Dispose of the spent cell according to local regulations for battery recycling.
Usage recommendations
Store unused cells in a cool, dry place away from direct sunlight. Replace batteries in pairs or as specified by the device manual when multiple cells are used. Keep button cells out of reach of children and pets; if swallowed, seek immediate medical attention. For devices with strict accuracy or safety requirements, consult the device documentation to confirm suitability of silver oxide chemistry.
