Uniross CR1220T HT Lithium Coin Cell Battery | 3V 38mAh High Temperature

Model No: CR1220T

The Uniross CR1220T HT delivers 38 mAh at a stable 3V in a 12.5mm diameter, 2.0mm profile — 52% more capacity than the CR1216T in the same 12.5mm footprint through an additional 0.4mm of cell height. The HT construction qualifies the CR1220T for operation from -30°C to +80°C, making it the correct specification wherever the 12.5mm format is required in automotive, outdoor, or elevated-temperature industrial applications.

Product Features

  • -30°C to +80°C operating range — extends reliable operation well beyond the standard CR1220 envelope; heat-resistant electrolyte prevents degradation at elevated ambient temperatures
  • 38 mAh — 52% more than CR1216T — additional height in the 12.5mm footprint provides substantially longer runtime for devices operating in temperature-demanding environments
  • 7-year shelf life — supports long-lifecycle embedded programmes and MRO stock programmes in variable-temperature storage
  • Stable 3V output across the full temperature range — consistent supply voltage for microcontrollers and RTC circuits operating in environments with wide thermal cycling
  • IEC 60086 & RoHS compliant — EU and UK market ready for automotive, industrial, and IoT OEM applications
