Suitable for

• Watches and wrist instruments
• Calculators and small handheld electronics
• Key fobs, remote controls, and garage remotes
• Medical devices with low power draw (e.g., glucose meters, thermometers)
• Memory backup and RTC (real-time clock) modules

Key specifications

• Nominal voltage: 3 V
• Cell type: Primary (non-rechargeable) lithium coin cell
• Form factor: Coin cell, diameter and thickness consistent with CR2477 standard size
• Typical applications: Low-to-moderate drain portable electronics and backup power
• Shelf life: Long-term storage with low self-discharge characteristics

How to use

Insert the battery into the device following the manufacturer’s polarity markings, ensuring the correct orientation of positive and negative terminals. Use only in devices specified for 3V lithium coin cells and avoid attempting to recharge the cell. Replace the battery when device performance degrades or when the device indicates low battery. Dispose of used batteries according to local regulations for lithium primary cells.

Usage recommendations

Store unused cells in a cool, dry place away from direct heat and sunlight. Avoid short-circuiting the terminals and keep batteries out of reach of children. When fitting the battery, ensure contacts are clean and free from corrosion for reliable electrical contact.
