The AA battery is the most widely used battery in the world, found in hundreds of thousands of devices. IEC codes for AA batteries include the popular LR6 for alkaline AA batteries and HR6 for NiMH rechargeable batteries. The standard voltage for these batteries is 1.5V, while rechargeable batteries generally deliver 1.2V. Newer AA lithium batteries offer a much higher 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 it was used for some time in flashlights and electrical novelties prior to formal standardization. ANSI and IEC battery nomenclature use different designations for cells of this size, depending on the cell's characteristics and chemistry. Each AA battery is 51 mm long and has a diameter of 14 mm. AA batteries are available in various formats, including alkaline, salt, long-life lithium, and rechargeable batteries with different capacities. AA alkaline batteries have a shelf life of approximately 6 years, while AA lithium equivalents last up to 9 years before use. Rechargeable AA batteries are now available in NiMH with a capacity of up to 2850 mAh and are also available with new "pre-charged" technology, allowing you to use them immediately. - Brand: Kodak - Type: AA Alkaline - Technology: Alkaline MAX stronger - Voltage: 1.5V
