Uniross CR2477 lithium coin cells deliver 1000 mAh at 3V in a 24.5mm diameter, 7.7mm profile — the highest-capacity cell in the Uniross CR S Type range. At 1 Ah, the CR2477 bridges the gap between coin cell and cylindrical primary battery formats, offering cellular IoT-class current ratings (7 mA continuous, 25 mA pulse) in a flat-disc form factor. For applications where a coin cell housing is mandated by the mechanical design but maximum energy reserve is the overriding engineering objective, the CR2477 is the definitive specification — enabling 5+ year battery life in low-to-medium duty cycle devices without increasing housing footprint.
