Common applications include fitness trackers, car key fobs, wearable health monitors, compact remote controls, and small LED devices where space is limited and frequent battery changes are impractical.\u003c\/p\u003e\n\u003cp\u003eLithium chemistry provides a flatter discharge curve than alkaline alternatives, meaning the battery maintains near-full voltage until close to the end of its life rather than gradually weakening. This makes the CR1620 particularly suited to devices with digital circuits that require stable voltage to function correctly. The battery operates reliably across a temperature range from -30°C to +60°C, covering both cold outdoor conditions and warm indoor environments without significant performance loss.\u003c\/p\u003e\n\u003cp\u003eThe single-battery blister pack includes child-resistant packaging that requires scissors to open, reducing the risk of accidental ingestion by young children. The CR1620 carries a shelf life of up to 10 years when stored at room temperature, so spare batteries can be kept on hand without concern about loss of charge. The battery weighs 1.2g and fits any device specifying a CR1620, 5009LC, DL1620, ECR1620, BR1620 or equivalent 16mm x 2mm lithium coin cell.\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 Specialist\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell Size\u003c\/td\u003e\n\u003ctd\u003eCR1620\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 CR1620 battery?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe CR1620 is commonly found in fitness trackers, car key fobs, wearable health monitors, compact remote controls, small LED lights, digital thermometers and medical devices. Any device specifying a CR1620, 5009LC, DL1620, ECR1620 or BR1620 can use this battery.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does a CR1620 last?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBattery life depends on the device's power draw. In a low-drain device like a car key fob the CR1620 can last 2-3 years. In higher-drain devices like fitness trackers or LED lights, expect 6-18 months depending on usage frequency.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the voltage of this battery?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe CR1620 delivers 3V nominal voltage. Lithium chemistry maintains near-full voltage throughout most of the discharge cycle, dropping sharply only near the end of battery life rather than gradually weakening like alkaline cells.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it be used in extreme temperatures?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The CR1620 operates from -30°C to +60°C, covering cold outdoor conditions and warm indoor environments. Performance is most stable between 0°C and 40°C, but the battery remains functional outside that range.\u003c\/p\u003e","brand":"Energizer","offers":[{"title":"Default Title","offer_id":46075167736075,"sku":"S341","price":1.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S341_1_ee32d8b2-f469-4287-8292-8f9e87e8d8bf.jpg?v=1730317673","url":"https:\/\/niori.co.uk\/products\/energizer-cr1620-lithium-coin-cell-battery-3v-1-pack","provider":"Niori","version":"1.0","type":"link"}
