CR1620 vs. LR44 / AG13
Comparing 2 standards across 6 specifications. 6 key differences identified.
Comparing:
CR1620
LR44 / AG13
A CR1620 coin cell is a 3.0V Lithium Manganese Dioxide battery measuring 16.0mm in diameter and 2.0mm in thickness. Like the thinner CR1616, it's a common choice for automotive key fobs and other compact keyless-entry remotes.
An LR44 battery is a 1.5V Alkaline button cell measuring 11.6mm in diameter and 5.4mm in thickness. SR44 is the Silver Oxide equivalent offering 1.55V with a flat discharge curve, critical for digital calipers.
