Uniross ML2020 lithium-aluminium rechargeable coin cells deliver 40 mAh at 3V in a 20.0mm diameter, 2.0mm profile — 33% more capacity than the ML2016 in the same footprint with a 0.4mm height increase. Where the mechanical design permits the 2.0mm height, the ML2020 is the preferred specification for rechargeable 20mm coin cell applications: it delivers the maximum energy available in the 1.6–2.0mm height range while maintaining 400 cycle capability at 10% DOD. Suitable for CMOS/RTC backup, ESL, and embedded sensor applications requiring a rechargeable 20mm coin cell. Available in bulk from European stock.
