The cylindrical CR2 cell measures 27mm in length and 15.6mm in diameter, fitting devices that specify CR15H270 or DLCR2 battery compatibility.\u003c\/p\u003e\n\u003cp\u003eLithium chemistry provides a higher energy density than alkaline equivalents, allowing the CR2 to maintain consistent voltage output even as the battery depletes. This makes it suitable for cameras and measuring instruments where voltage drop would affect performance or accuracy. The battery retains charge during storage better than alkaline cells, with a shelf life of up to 10 years when stored at room temperature.\u003c\/p\u003e\n\u003cp\u003eThe CR2 delivers reliable performance across a temperature range from -20°C to +60°C, making it suitable for outdoor use in winter conditions where alkaline batteries would struggle. The lithium construction keeps the cell lightweight at 11g despite the higher capacity, and the sealed design prevents leakage during normal use and storage.\u003c\/p\u003e\n\u003cp\u003eThis single-pack format suits users replacing a depleted CR2 in an existing device rather than stocking spares. The blister pack protects the battery terminals during storage and transport, and includes child-resistant packaging to meet UK safety standards.\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\u003eWidth (mm)\u003c\/td\u003e\n\u003ctd\u003e86\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Range\u003c\/td\u003e\n\u003ctd\u003eDuracell 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 devices use CR2 batteries?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCR2 batteries are commonly found in compact film and digital cameras, rangefinders, laser sights, compact LED torches and some medical devices. Check your device's battery compartment or manual for CR2, CR15H270 or DLCR2 compatibility.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does a CR2 lithium battery last in storage?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDuracell lithium CR2 batteries have a shelf life of up to 10 years when stored at room temperature in the original packaging. Lithium cells self-discharge more slowly than alkaline batteries, making them suitable for emergency kit and infrequently-used devices.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan CR2 batteries be recharged?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The Duracell Ultra CR2 is a primary (non-rechargeable) lithium cell. Attempting to recharge it can cause leakage, overheating or rupture. Only use rechargeable CR2 cells if your device specifically supports them.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat voltage does the CR2 provide?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe CR2 delivers 3V nominal voltage. This is higher than the 1.5V of a single AA or AAA cell, which is why two CR2 batteries are sometimes used in series to provide 6V in certain camera models.\u003c\/p\u003e","brand":"Duracell","offers":[{"title":"Default Title","offer_id":46075179794699,"sku":"S386","price":3.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S386_1_60fc9d0d-acea-46c7-9d70-a4b3f65d6a57.jpg?v=1730317725","url":"https:\/\/niori.co.uk\/products\/duracell-ultra-cr2-3v-lithium-battery-single-pack","provider":"Niori","version":"1.0","type":"link"}
