Uniross CR2477 Lithium Coin Cell Battery | Industrial Bulk Supply

Model No: CR2477

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.

Product Features

  • 1000 mAh — highest capacity in the CR S Type range — positions the CR2477 at the boundary between coin cell and cylindrical primary formats; enables 5+ year battery life in medium duty cycle devices without increasing housing footprint or moving to a different cell format
  • 7 mA continuous / 25 mA pulse — supports cellular IoT module operation, GPS acquisition, and power-intensive wireless transmission bursts within rated current without voltage collapse
  • Stable 3V flat discharge — predictable, consistent voltage delivery for power-managed embedded systems across multi-year deployment cycles; eliminates voltage-related performance drift in long-deployed equipment
  • 5-year shelf life — pre-installation ready; supports long supply chain holding times and extended MRO stock programmes without capacity degradation or the need for pre-deployment conditioning
  • IEC 60086 & RoHS compliant — EU and UK market qualified; applicable to the most demanding cellular IoT, infrastructure, and medical OEM supply chains
