Uniross CR2032 Lithium Coin Cell Battery | Industrial Bulk Supply

Model No: CR2032

Uniross CR2032 lithium coin cells deliver 220 mAh at a stable 3V in a 20mm diameter, 3.2mm profile — the world’s most widely specified lithium primary cell. The CR2032 is the default specification for CMOS and RTC backup in embedded systems, the standard reference design for automotive key fobs, and the cell against which all alternative coin cells are benchmarked. When procurement teams require a reliable, globally recognised cell with broad device compatibility and consistent European supply, the CR2032 is the baseline specification for production and MRO programmes alike.

Product Features

  • 220 mAh — highest capacity standard 20mm coin cell — maximises runtime and reduces battery replacement frequency across the most widely deployed coin cell footprint; directly lowers total cost of ownership in high-volume device programmes
  • 5 mA continuous / 15 mA pulse — rated for CMOS backup, wireless burst transmission, and periodic sensor polling across automotive, IoT, medical, and embedded computing applications without voltage collapse
  • Stable 3V flat discharge — the flat voltage profile is critical for RTC circuits, voltage supervisors, and voltage-sensitive microcontrollers that require supply stability across the full discharge cycle
  • 5-year shelf life — low self-discharge supports long-lifecycle embedded system programmes and high-volume MRO stock holding without capacity degradation between production runs
  • IEC 60086 & RoHS compliant — the global industry standard cell; EU and UK market ready for automotive, medical, industrial, and electronics OEM supply chains without additional qualification
