Each cell measures 20mm diameter by 1.6mm height and delivers stable 3V output for compact electronics that require a CR2016 cell, including car key fobs, glucose monitors, fitness trackers, small LED torches and calculators.\u003c\/p\u003e\n\u003cp\u003eDesigned for devices with low to moderate continuous drain, the CR2016 uses lithium manganese dioxide chemistry to maintain voltage stability across the discharge curve. The 2-pack format provides a spare cell for emergency replacement or for powering a second device. Lithium cells operate across a wider temperature range than alkaline equivalents, making them suitable for outdoor devices and car remotes exposed to heat or cold.\u003c\/p\u003e\n\u003cp\u003eEach cell weighs approximately 1.8g and is sealed in a corrosion-resistant stainless steel casing. The low self-discharge rate of lithium chemistry means unused cells retain charge for several years in storage. Energizer prints the expiry date on each cell and the blister packaging, with this batch showing a best-before date of 07\/2029.\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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth (mm)\u003c\/td\u003e\n\u003ctd\u003e80\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\u003e120\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\u003eCR2016\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 CR2016 batteries?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCR2016 cells are commonly used in car key fobs, remote controls, glucose monitors, fitness trackers, bike computers, small LED keyring torches, calculators and watch batteries for larger watch movements. Check your device's battery compartment or manual to confirm the required cell size before purchasing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between CR2016 and CR2032?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBoth are 20mm diameter lithium coin cells at 3V, but the CR2032 is twice as thick at 3.2mm versus 1.6mm for the CR2016. The CR2032 has approximately double the capacity. They are not interchangeable — use only the size specified by your device.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long do CR2016 batteries last?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eShelf life is typically 8-10 years from manufacture when stored at room temperature. In-device life depends on the current draw of the electronics. A car remote used several times daily might run for 1-2 years, while a low-draw device like a glucose monitor backup cell may last 3-4 years.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these batteries rechargeable?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. CR2016 lithium coin cells are single-use primary cells and cannot be recharged.
