LR41 / AG3 vs. LR44 / AG13
Comparing 2 standards across 6 specifications. 6 key differences identified.
An LR41 battery (also sold as AG3 or 392) is a 1.5V Alkaline button cell measuring approximately 7.9mm in diameter and 3.6mm in thickness. It's a common size for small thermometers, compact watches, and other low-drain miniature electronics.
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.
