CR2477 vs. LR41 / AG3
Comparing 2 standards across 4 specifications. 4 key differences identified.
Comparing:
CR2477
LR41 / AG3
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.
An LR41 battery (also sold as AG3 or 392) is a 1.5V Alkaline button cell measuring approximately 7.9mm in diameter and 3.6mm in thickness. It's a common size for small thermometers, compact watches, and other low-drain miniature electronics.
