Uniross CR1225 lithium coin cells deliver 50 mAh at 3V in a 12.5mm diameter, 2.5mm profile — the highest-capacity primary cell available in the 12mm diameter series. When the 12mm battery compartment is mandated by device housing geometry and maximum runtime is the primary engineering objective, the CR1225 is the top specification within this footprint family. It is the standard choice for watches, medical devices, and IoT sensor nodes where the longest possible service interval within a 12mm housing is the priority.
