CR2025 vs. LR41 / AG3
Comparing 2 standards across 5 specifications. 5 key differences identified.
Comparing:
CR2025
LR41 / AG3
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 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.
