Comparing:
CR1616
SR626SW / 377
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 SR626SW (also sold as 377) is a 1.55V Silver Oxide button cell measuring approximately 6.8mm in diameter and 2.6mm in thickness. It's one of the most common watch battery sizes, prized for the flat, stable discharge voltage silver oxide chemistry provides over the cell's life.
