This 2-pack contains two cells designed for low-drain devices that require a compact 6V power source, including garage door remotes, wireless doorbells, keyless entry fobs, and certain medical alert pendants.\u003c\/p\u003e\n\u003cp\u003eThe A11 size is less common than AA or AAA batteries, so devices that require it typically have no alternative power option. The alkaline chemistry provides steady voltage output across the cell's discharge cycle, making it suitable for devices that need consistent power delivery rather than high-current bursts. Shelf life is typically 5-7 years when stored at room temperature.\u003c\/p\u003e\n\u003cp\u003eEach cell weighs 10g and delivers 6V nominal output from a single-cell construction, unlike 9V batteries which use six internal 1.5V cells. The slim 11mm diameter allows the A11 to fit into narrow battery compartments in garage door transmitters and compact medical devices where wider battery formats would not physically fit. The Energizer branding on the cell casing runs lengthwise along the cylinder.\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\u003e11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd\u003e80\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\u003eA11\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell Composition\u003c\/td\u003e\n\u003ctd\u003eAlkaline\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 A11 batteries?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA11 batteries power garage door remotes, wireless doorbell transmitters, keyless car entry fobs, and certain medical alert pendants. The slim 11mm diameter fits devices where wider battery formats would not physically fit. Check your device's battery compartment or manual to confirm compatibility.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long do A11 batteries last?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBattery life depends on the device's power draw. In a garage door remote used a few times daily, an A11 battery typically lasts 1-2 years. In a medical alert pendant with continuous standby draw, expect 3-6 months. Low-battery indicators in the device will signal when replacement is needed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use a different battery size instead?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Devices designed for A11 batteries have battery compartments sized to the 11mm diameter and 120mm length. Larger formats like AA or 9V will not fit, and there is no electrical adapter to substitute a different size.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the shelf life?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEnergizer alkaline batteries have a shelf life of 5-7 years when stored at room temperature in their original packaging.
