Comparing:
CR2450
LR41 / AG3
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.
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.
