CR2016 vs. CR2450

A CR2016 coin cell is a 3.0V Lithium Manganese Dioxide battery measuring 20.0mm in diameter and 1.6mm in thickness with a nominal capacity of about 90 mAh. Its slim profile suits low-profile devices like slim remotes, LED tea lights, and thin calculators, distinguishing it from the thicker CR2032 of the same diameter.

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.
