Uniross CR1632 lithium coin cells deliver 120 mAh at 3V in a 16mm diameter, 3.2mm profile — the highest-capacity primary cell in the 16mm diameter series, providing 71% more energy than the CR1620 within the same footprint. When designs are fixed at the 16mm housing diameter and maximum runtime is the priority, the CR1632 is the top specification — significantly reducing field maintenance frequency compared to CR1616 and CR1620 alternatives. It is commonly specified in key fobs, industrial sensors, and medical devices where extended service intervals reduce total cost of ownership.
