Uniross CR2020 lithium coin cells deliver 130 mAh at 3V in a 20mm diameter, 2.0mm profile — 63% more capacity than the CR2016 within the same 20mm footprint at a 0.4mm increase in cell height. When the 20mm battery compartment is fixed and maximum runtime within a tight height budget is the engineering objective, the CR2020 provides the optimum balance between energy density and profile within the 20mm family. It is specified in automotive electronics, key fobs, and IoT sensors where extended service intervals translate directly to reduced maintenance cost.
