The lithium chemistry provides stable voltage output across the battery's discharge cycle and retains charge during storage better than alkaline equivalents.\u003c\/p\u003e\n\u003cp\u003eSupplied as a single battery in child-resistant blister packaging with a tamper-evident seal, the CR1216 suits emergency replacement for devices where the battery has depleted unexpectedly or as a spare for travel kits. The blister pack keeps the cell isolated from metal objects that could cause short-circuits during storage in bags or toolboxes. The battery's nominal capacity depends on the discharge rate and device draw, but typical shelf life is 8-10 years when stored at room temperature.\u003c\/p\u003e\n\u003cp\u003eEnergizer's leak-resistant construction uses a seal design that minimises the risk of electrolyte leakage even when the cell is fully discharged, protecting the device's internal contacts from corrosion. The 1.6mm thickness makes the CR1216 one of the thinner coin cells in the CR range, suited to slim-profile key fobs and watches where a CR2032 (3.2mm thick) would not fit. The 3V output is compatible with devices rated for CR1216 specifically — using a different-sized coin cell can damage circuitry or cause the device to malfunction.\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\u003eCR1216\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 CR1216 battery?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe CR1216 is commonly found in car key fobs, slim watches, fitness trackers, small calculators, glucose monitors and some motherboard CMOS backup cells. Check your device's battery compartment or manual to confirm the correct size before purchasing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does a CR1216 last?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBattery life depends on the device's power draw. In a low-drain watch the CR1216 may last 2-3 years; in a car key fob with frequent button presses it may last 1-2 years. Shelf life when stored unused is typically 8-10 years.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use a CR1220 instead of a CR1216?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The CR1220 is 2.0mm thick versus the CR1216's 1.6mm thickness. Forcing a thicker cell into a device designed for CR1216 can damage the battery compartment or prevent the cover from closing properly. Always use the exact size specified by the device manufacturer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the packaging child-resistant?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The blister pack includes a child-resistant seal that requires adult dexterity to open, reducing the risk of accidental ingestion by children. Coin cells are a choking and poisoning hazard if swallowed.\u003c\/p\u003e","brand":"Energizer","offers":[{"title":"Default Title","offer_id":46075154923787,"sku":"S317","price":1.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S317_1_df0d2f33-e954-4b5a-a4ea-e22f2fc982ba.jpg?v=1730317612","url":"https:\/\/niori.co.uk\/products\/energizer-cr1216-3v-lithium-coin-cell-battery-single-pack","provider":"Niori","version":"1.0","type":"link"}
