Uniross CR1216 Lithium Coin Cell Battery | Industrial Bulk Supply

Model No: CR1216

Uniross CR1216 lithium coin cells deliver 25 mAh at 3V in a 12.5mm diameter, 1.6mm profile — the thinnest primary cell available in the 12mm diameter series. When the 12mm footprint is fixed by housing geometry and component height is the binding constraint, the CR1216 is the specification of record for slim wristwatches, card-format smart devices, and thin-profile medical patches where any taller cell would exceed height clearance. Supplied in bulk from European stock to suit OEM and volume procurement requirements.

Product Features

  • 1.6mm profile — thinnest cell in the 12mm diameter family — enables specification in the slimmest device housings within the 12mm footprint; every higher-capacity alternative in this series exceeds the height clearance this cell achieves
  • Stable 3V flat discharge — consistent voltage output across the discharge cycle for reliable operation of RTCs, microcontrollers, and low-power sensors in precision devices
  • 5-year shelf life — designed for long-lifecycle OEM products and low-turnover MRO stock; minimal capacity loss during extended storage periods
  • -20°C to +60°C operating range — suitable for professional indoor environments, sheltered industrial installations, and medical device applications
  • IEC 60086 & RoHS compliant — meets European regulatory standards; qualified for EU and UK commercial, medical, and industrial supply chains without additional testing
