Uniross CR3032 lithium coin cells deliver 500 mAh at 3V in a 30mm diameter, 3.2mm profile. The larger 30mm footprint enables significantly higher current ratings — 10 mA continuous and 30 mA pulse — making the CR3032 the specification of choice when current demand has exceeded the capability of 24.5mm cells and a flat coin cell format must be retained. It is used in demanding cellular IoT applications, motorised access control systems, and industrial wireless equipment where high peak currents are required alongside a substantial energy reserve in a flat-disc housing.
