The lithium chemistry delivers consistent 3V output throughout its discharge cycle, maintaining stable performance until the cell is depleted.\u003c\/p\u003e\n\u003cp\u003eThis single-cell pack suits replacement battery needs for devices with a CR1220 cell socket. The battery carries an 8-year shelf life when stored at room temperature, retaining its charge without significant degradation over time, which makes it suitable for stocking spares or emergency kits where batteries may sit unused for extended periods. The operating temperature range of -30°C to 60°C allows the battery to function in both cold outdoor environments and warm indoor conditions without performance loss.\u003c\/p\u003e\n\u003cp\u003eThe blister packaging includes child-resistant features designed to reduce the risk of young children accessing the battery. The lithium cell construction is leak-resistant, protecting device contacts and circuitry from corrosion damage that can occur with alkaline chemistries. The CR1220 designation is an IEC standard size reference, ensuring cross-compatibility with devices specifying this cell size regardless of manufacturer.\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\u003e0.01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth (mm)\u003c\/td\u003e\n\u003ctd\u003e44\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd\u003e89\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Range\u003c\/td\u003e\n\u003ctd\u003eEnergizer Lithium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell Size\u003c\/td\u003e\n\u003ctd\u003eCR1220\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 a CR1220 battery?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCR1220 cells are commonly used in watches, car key fobs, fitness trackers, glucose monitors, heart-rate monitors, small LED lights, calculators and electronic organisers. Any device specifying a CR1220 in its manual or battery compartment will accept this cell.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does the CR1220 last in storage?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEnergizer rates the CR1220 for an 8-year shelf life when stored at room temperature in its original packaging. This means the battery retains most of its charge over that period, making it suitable for keeping spares on hand.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the CR1220 the same as a BR1220?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. CR1220 and BR1220 are the same physical size (12mm diameter, 2mm thick) but use different lithium chemistries. CR cells use lithium manganese dioxide; BR cells use lithium carbon monofluoride. CR cells deliver higher current drain; BR cells offer longer shelf life in low-drain devices. Check your device manual for the correct type.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I recharge a CR1220?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. CR1220 cells are primary (non-rechargeable) lithium batteries. Attempting to recharge them can cause leakage, rupture or fire. Replace them with a new cell when depleted.\u003c\/p\u003e","brand":"Energizer","offers":[{"title":"Default Title","offer_id":46075155448075,"sku":"S320","price":1.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S320_1_f9ce8393-52be-4cc1-adbe-f9bd5495d170.jpg?v=1730317615","url":"https:\/\/niori.co.uk\/products\/energizer-cr1220-3v-lithium-coin-cell-battery-single-pack","provider":"Niori","version":"1.0","type":"link"}
