Battery Akyga CR2477 3 V 1000 mAh Li-MnO2 coin cell, single pack

Akyga CR2477 is a 3 V Li-MnO2 coin cell battery with a nominal capacity of 1000 mAh supplied as a single unit. It provides a stable 3 V output and long shelf life, making it suitable for replacement and maintenance of low- to moderate-drain electronics. The battery is designed to fit devices that accept the CR2477 size and offers consistent performance for backup power and small electronic applications.

Advantages

The battery delivers a reliable and stable voltage throughout its discharge cycle, supporting devices that require a constant 3 V source. Its nominal 1000 mAh capacity offers extended operational time compared with lower-capacity coin cells. The Li-MnO2 chemistry ensures low self-discharge and long storage life, and the single-pack format allows for straightforward replacement without excess packaging.

Suitable for

• Memory backup for electronics and controllers
• Small portable devices and sensors
• Watches and timekeeping modules that accept CR2477 size
• Medical devices with low to moderate power draw
• Remote controls and key fobs

Key specifications

• Nominal voltage: 3 V
• Typical capacity: 1000 mAh
• Battery chemistry: Lithium Manganese Dioxide (Li-MnO2)
• Cell format: coin cell (CR2477 size)
• Packaging: single unit
• Storage characteristic: low self-discharge, long shelf life

How to use

Insert the coin cell into the device following the polarity markings: the flat positive side typically faces up. Ensure the device is powered off or in a safe state before replacing the battery. Use a non-conductive tool or gloves if required to avoid short circuits and to maintain clean contact surfaces. After installation, verify correct seating and device operation. Dispose of the old battery according to local regulations for lithium primary cells.

Usage recommendations

Store unused batteries in a cool, dry place away from metal objects and direct sunlight. Do not recharge, short-circuit, puncture or incinerate the cell. For best performance, replace batteries before they reach critically low voltage to prevent data loss in memory-backed devices.
