Each cell measures 20mm diameter by 3.2mm height and uses lithium manganese dioxide chemistry to deliver 3V nominal voltage with a capacity of approximately 220mAh. The cells carry a 10-year shelf life from manufacture date and operate across a temperature range of -20°C to +65°C.\u003c\/p\u003e\n\u003cp\u003eCR2032 cells power car key fobs, bathroom scales, kitchen timers, fitness trackers, glucose meters, bike computers, remote controls, motherboard CMOS memory, small LED lights, and various medical devices requiring stable 3V input. The coin form factor fits into compact battery compartments where cylindrical AA or AAA cells would not, making them the standard power source for miniaturised electronics. The lithium chemistry holds voltage steadier than alkaline under low-draw conditions and performs better in cold environments.\u003c\/p\u003e\n\u003cp\u003ePanasonic manufactures these cells in Indonesia using their Cell Power Lithium technology, which bonds the lithium anode to the cell casing to reduce internal resistance and improve energy density. The flat discharge curve means devices receive consistent voltage throughout most of the cell's usable life rather than experiencing gradual dimming or slowing. Each cell weighs 3g and the blister pack dimensions are 95mm x 50mm x 5mm, making them easy to store in a drawer or carry in a bag.\u003c\/p\u003e\n\u003cp\u003eThe child-safety packaging meets EU regulations with a difficult-to-open blister that reduces risk of accidental ingestion by children under 36 months. The 0% mercury and cadmium formulation makes disposal simpler under UK battery recycling schemes compared to older button cell chemistries.\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\u003e95\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e50\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Range\u003c\/td\u003e\n\u003ctd\u003ePanasonic Specialist\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell Size\u003c\/td\u003e\n\u003ctd\u003eCR2032\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\u003eHow long do CR2032 batteries last in typical devices?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLifespan depends on the device's current draw. In a car key fob or bathroom scale with intermittent use, a CR2032 typically lasts 2-5 years. In a continuously-powered device like a motherboard CMOS or a real-time clock, expect 3-10 years depending on the specific circuit design.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use CR2032 batteries in watches?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, CR2032 cells are commonly used in digital watches and some analogue quartz watches with larger battery compartments. Check your watch manual to confirm CR2032 is the specified cell type before replacing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between CR2032 and CR2025?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCR2032 is 3.2mm thick; CR2025 is 2.5mm thick. Both are 20mm diameter and deliver 3V, but the CR2032 has higher capacity (approximately 220mAh vs 165mAh) due to the extra thickness. Devices designed for CR2032 will not close properly with a CR2025, and vice versa.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these batteries rechargeable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. CR2032 lithium coin cells are single-use primary batteries and must not be recharged. Attempting to recharge them can cause leakage, venting or rupture. Rechargeable equivalents use different chemistry (LIR2032) and are not interchangeable with CR2032 cells.\u003c\/p\u003e","brand":"Panasonic","offers":[{"title":"Default Title","offer_id":46075210137867,"sku":"S5284","price":1.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S5284_1_8fc7737a-6b6d-4ed1-88f3-22d91292790d.jpg?v=1730317890","url":"https:\/\/niori.co.uk\/products\/panasonic-cr2032-3v-lithium-coin-cell-batteries-2-pack","provider":"Niori","version":"1.0","type":"link"}
