Uniross CR3032 Lithium Coin Cell Battery | Industrial Bulk Supply

Model No: CR3032

Uniross CR3032 lithium coin cells deliver 500 mAh at 3V in a 30mm diameter, 3.2mm profile. The larger 30mm footprint enables significantly higher current ratings — 10 mA continuous and 30 mA pulse — making the CR3032 the specification of choice when current demand has exceeded the capability of 24.5mm cells and a flat coin cell format must be retained. It is used in demanding cellular IoT applications, motorised access control systems, and industrial wireless equipment where high peak currents are required alongside a substantial energy reserve in a flat-disc housing.

Product Features

  • 10 mA continuous / 30 mA pulse — highest current in the standard S Type range — enables specification in applications involving motorised actuators, cellular modems, and power-intensive wireless protocols that exceed the 24.5mm series capability; eliminates the need to step up to cylindrical formats for many high-current OEM designs
  • 500 mAh energy reserve — substantial capacity supports long-duration deployment in equipment with elevated current duty cycles; reduces field maintenance frequency despite higher average current draw
  • Stable 3V flat discharge under high-drain loads — maintains supply voltage within specification for demanding embedded systems even during sustained 10 mA draw
  • 5-year shelf life — supports long MRO holding and pre-installed battery programmes in industrial and infrastructure equipment
  • IEC 60086 & RoHS compliant — EU and UK market qualified; applicable to access control, industrial automation, and cellular IoT OEM programmes
