CR2016 vs. LR41 / AG3

Comparing 2 standards across 5 specifications. 5 key differences identified.

Comparing:
CR2016
LR41 / AG3

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.
