CR2025 vs. SR626SW / 377
Comparing 2 standards across 5 specifications. 5 key differences identified.
A CR2025 coin cell measures 20.0mm in diameter and 2.5mm in height, supplying 3.0V at ~165 mAh. While identical in diameter to the CR2032, its thinner 2.5mm profile prevents reliable contact in CR2032 battery holders.
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.
