Each cell delivers a stable 3V output through its lithium chemistry, making it suitable for devices requiring consistent voltage rather than gradual decline during discharge.\u003c\/p\u003e\n\u003cp\u003eDesigned for digital cameras, professional flash units, rifle scopes and night-vision equipment, the CR2 provides the rapid energy discharge these devices need during high-draw moments such as flash recycle or image capture. The compact size fits devices where internal space is limited, and the light 11g weight per cell makes them suitable for handheld and portable equipment where battery weight is a consideration.\u003c\/p\u003e\n\u003cp\u003eEnergizer rates the CR2 with a 10-year shelf life when stored at room temperature, allowing spare cells to be kept in camera bags or equipment cases without significant capacity loss. The lithium chemistry maintains voltage output across a wider temperature range than alkaline cells, making the CR2 reliable in both cold outdoor photography sessions and warm indoor studio work. Each pack contains two cells sealed in blister packaging.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.02\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Range\u003c\/td\u003e\n\u003ctd\u003eEnergizer Specialist\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell Size\u003c\/td\u003e\n\u003ctd\u003eCR2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell Composition\u003c\/td\u003e\n\u003ctd\u003eLithium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat voltage does the CR2 provide?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEach CR2 cell delivers 3V output.
