Panasonic CR2477bn Lithium Coin Cell

This Panasonic CR2477bn is a 3 V lithium coin cell built for devices that need a compact, reliable power source. It fits remotes, medical sensors, fitness trackers and other small electronics that accept the CR2477 form factor.

Capacity and typical runtime

The cell delivers high energy density and a continuous voltage supply, keeping low-drain devices running for extended periods. Shelf life reaches up to 10 years, so spares stay ready. It is not suited for high-drain applications that demand sustained heavy current.

Thermals, noise and power draw

Lithium chemistry provides stable output across a broad temperature range, making it dependable in both cool and warm environments. The battery has no moving parts, so it operates silently and adds no parasitic draw to the host device.

Questions about this item

Will the 24.5 mm diameter CR2477bn fit the same holder as my older CR2477 cell?

Yes, both share the 24.5 mm diameter and 3 V chemistry, so the CR2477bn sits in the same holder as a standard CR2477.

How can I confirm the 3 V lithium cell is delivering power after installation?

Measure the voltage across the terminals with a multimeter; a fresh Panasonic CR2477bn should read close to 3 V under no load.

Does the package include more than the single coin cell, or must I buy a holder separately?

The box contains only the Panasonic CR2477bn battery; any holder, clip or solder tab must be purchased separately.
