Uniross CR1620 lithium coin cells deliver 70 mAh at 3V in a 16mm diameter, 2.0mm profile — 40% more capacity than the CR1616 in the same footprint, with identical current ratings of 3 mA continuous and 8 mA pulse. When a device is sized for the 16mm battery compartment and service interval is the primary engineering objective, the CR1620 is the preferred upgrade over the CR1616 — reducing maintenance and field replacement costs without any housing redesign. It is widely specified in key fobs, medical wearables, and IoT nodes where longer deployment between battery changes is a measurable operational advantage.
