Uniross CR2440 lithium coin cells deliver 480 mAh at 3V in a 24.5mm diameter, 4.0mm profile — 78% more capacity than the CR2430 within the same footprint, with identical current ratings of 7 mA continuous and 25 mA pulse. For applications using the 24.5mm battery housing where height permits 4.0mm and multi-year runtime is a primary design requirement, the CR2440 is the preferred specification. It is widely used in GPS tracking, cellular IoT, and long-lifecycle industrial monitoring equipment where battery replacement must be minimised to reduce operational and maintenance cost.
