PANASONIC – BRONZE AA LR6 4U BATTERY

The AA battery is the most widely used battery in the world and can be found in hundreds of thousands of devices. IEC codes for AA batteries include the popular LR6 for alkaline AA batteries and HR6 for rechargeable NiMH batteries. The standard voltage for these batteries is 1.5 V, while rechargeable batteries typically provide 1.2 V. Newer lithium AA batteries offer significantly greater capacity at a slightly higher price. Introduced in 1907, the AA battery size was standardized by the American National Standards Institute (ANSI) in 1947, but had already been used in flashlights and electrical novelties for some time before formal standardization. The ANSI and IEC battery nomenclature gives various designations for cells of this size, depending on cell characteristics and chemistry. Each AA battery has a length of 51 mm and a diameter of 14 mm. The formats in which AA batteries are available are: alkaline batteries, saline batteries, long-life lithium batteries, and rechargeable batteries of different capacities. Alkaline AA batteries have a lifespan of about 6 years, while their lithium AA equivalents last up to 9 years before use. Rechargeable AA batteries are now available in NiMH with capacities up to 2850mAh and are also available in the new "pre-charged" technology that allows you to use them directly from the packaging.
