PANASONIC - BRONZE BATTERY AA LR6 4U

The AA battery is the most popular battery in the world and can be found in hundreds of thousands of devices. IEC codes for AA batteries include the popular LR6 for AA and HR6 alkaline batteries for rechargeable NiMH batteries. The normal voltage for these batteries is 1.5V, while rechargeable batteries usually provide 1.2V. The new 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 was used in flashlights and electrical novelties for some time prior to formal standardization. ANSI and IEC battery nomenclature specify 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 the AA battery is available are: alkaline batteries, zinc-carbon batteries, long-life lithium batteries and rechargeable batteries with different capacities. AA alkaline batteries have a shelf life of approx. 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 2850 mAh and are also available in the new "pre-charged" technology which allows you to use them straight out of the package.
