Key specifications

• Nominal voltage: 3 V
• Cell type: Lithium coin cell
• Physical format: 16 mm diameter, 3.2 mm thickness (nominal by type)
• Typical applications: low-drain electronic devices
• Storage characteristics: low self-discharge, long shelf life

How to use

Insert the coin cell into the device battery compartment observing polarity markings: the positive terminal faces outward where indicated. Ensure the contact surfaces inside the device are clean and free of corrosion before insertion. For devices with a retained battery holder or clip, press the cell gently into place until it is secure; avoid bending metal contacts. Replace battery only with the same type and nominal voltage to maintain device functionality.

Usage recommendations

Store unused cells in a cool, dry place away from direct sunlight and heat sources. Do not attempt to recharge primary lithium cells, and keep them away from children. Dispose of used batteries according to local regulations for battery recycling or hazardous waste collection.
