Uniross CR1225T HT Lithium Coin Cell Battery | 3V 50mAh High Temperature

Model No: CR1225T

The Uniross CR1225T HT is the highest capacity cell in the 12.5mm HT family, delivering 50 mAh at a stable 3V in a 12.5mm diameter, 2.5mm profile. It provides the maximum runtime available in the 12mm coin cell format while retaining the full -30°C to +80°C operating envelope of the HT range. For designs constrained to the 12.5mm footprint that operate in elevated-temperature environments, the CR1225T HT is the definitive specification.

Product Features

  • 50 mAh — maximum capacity in the 12.5mm HT family — the deepest cell in the 12mm range delivers the longest runtime for temperature-demanding applications within the 12.5mm footprint constraint
  • -30°C to +80°C operating range — heat-resistant electrolyte, reinforced shell, and advanced sealing ensure reliable performance across automotive, outdoor, and industrial thermal environments
  • 7-year shelf life — minimises battery replacement frequency in remote or inaccessible deployments where maintenance is costly
  • Stable 3V across the full temperature window — consistent supply for RTC circuits, wireless sensor front-ends, and low-power microcontrollers exposed to thermal cycling
  • IEC 60086 & RoHS compliant — EU and UK market ready without additional qualification
