Uniross CR927 Lithium Coin Cell Battery | Industrial Bulk Supply

Model No: CR927

Uniross CR927 lithium coin cells deliver reliable 3V power in the most constrained housing geometry in the CR range — a 9.5mm diameter, 2.7mm thick cell rated at 30 mAh. When device housing constraints eliminate every other option, the CR927 is the specified solution for miniature medical sensors, compact hearing instruments, and ultra-small wireless electronics that require a primary power source in the tightest possible footprint. Available in bulk from European stock with lead times and OEM quantities to suit medical device and electronics manufacturers.

Product Features

  • Ultra-compact 9.5mm footprint — the smallest diameter in the CR lithium range; enables specification in housings where no larger coin cell can be accommodated, making it the only viable primary power source in the most space-constrained OEM designs
  • Stable 3V flat discharge — consistent output voltage throughout the discharge cycle keeps voltage-sensitive microelectronics, RTCs, and sensors operating within specification from first use to end of life
  • 5-year shelf life — low self-discharge rate supports slow-moving MRO inventory and long-lifecycle device programmes without capacity write-off risk during extended storage
  • -20°C to +60°C operating range — qualifies for indoor professional, medical, and sheltered industrial deployment without additional thermal conditioning
  • IEC 60086 & RoHS compliant — manufactured to European standards; no additional regulatory qualification required for EU and UK market deployment in medical and industrial applications
