PANASONIC - BRONZE BATTERY AA LR6 4U

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 AA and HR6 alkaline for rechargeable NiMH batteries. The normal voltage for these batteries is 1.5V, while rechargeable batteries typically provide 1.2V. The new AA lithium batteries offer 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 was used in flashlights and electrical novelties for some time before formal standardization. ANSI and IEC battery nomenclature gives different designations for cells of this size, depending on the characteristics of the cell and chemistry. Each AA battery is 51 mm long and 14 mm in diameter. The formats in which the AA battery is available are: alkaline, salt, long-life lithium and rechargeable batteries of varying capacities. AA alkaline batteries have a shelf life of approximately 6 years, while AA lithium equivalents last up to 9 years before use. AA rechargeable 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 straight out of the box.
