Comparing:
CR1616
LR44 / AG13
A CR1616 coin cell is a 3.0V Lithium Manganese Dioxide battery measuring 16.0mm in diameter and 1.6mm in thickness. Its slim, compact size makes it a common choice for car key remotes and other small keyless-entry fobs.
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.
