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.
