CR2450 vs. CR2477

A CR2450 coin cell is a 3.0V Lithium Manganese Dioxide battery measuring 24.5mm in diameter and 5.0mm in thickness, with a nominal capacity of about 610 mAh -- among the largest standard coin cells. It's commonly used in larger remote controls, TPMS sensors, and medical alert devices needing extended runtime.

A CR2477 coin cell is a 3.0V Lithium Manganese Dioxide battery measuring 24.5mm in diameter and 7.7mm in thickness -- the largest-capacity cell in the common CR-series lithium coin cell line. Its size suits devices needing extended runtime from a single coin-shaped cell, such as larger remote controls and industrial sensors.
