Uniross ML1220 Lithium Rechargeable Coin Cell Battery | Industrial Bulk Supply

Model No: ML1220

Uniross ML1220 lithium-aluminium rechargeable coin cells deliver 18 mAh at 3V in a compact 12.5mm diameter, 2.0mm profile. Designed for OEM applications where a coin cell housing is fixed by mechanical design and the circuit includes a charging provision, the ML1220 replaces a non-rechargeable primary with a cell rated for up to 300 charge/discharge cycles at 10% depth of discharge — reducing field service requirements and total battery cost over the product lifecycle. Operates reliably from -20°C to +60°C and available in bulk quantities from European stock.

Product Features

  • Up to 300 charge/discharge cycles — rated for 300 cycles at 10% DOD and 120 cycles at 20% DOD; suitable for OEM products with integral charging circuits where replacing a primary battery periodically is not operationally viable
  • 3V stable output in the 12.5mm coin format — drop-in rechargeable equivalent for CR1220-footprint designs; eliminates field battery replacement in sealed or surface-mount assemblies where cell access is restricted
  • -20°C to +60°C operating range — maintains charge retention and cycle performance across industrial ambient temperature ranges; qualified for outdoor infrastructure and uncontrolled environments
  • 5-year shelf life — supports long supply chain holding periods and pre-installed stock programmes without capacity loss; cells arrive at the production line ready for immediate use
  • IEC 60086 & RoHS compliant — EU and UK market ready; applicable to industrial automation, medical device, and consumer electronics OEM supply chains requiring documented compliance
