4 KODAK XTRALIFE AA LR6 ALKALINE BATTERIES

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 AA alkaline batteries and HR6 for NiMH rechargeable batteries. The normal voltage of these batteries is 1.5 V, while rechargeable batteries generally deliver 1.2 V. 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 had been used in flashlights and electrical novelties for some time before formal standardization. ANSI and IEC battery nomenclature give different designations for cells of this size, depending on cell characteristics and chemistry.

Each AA battery is 51 mm long and 14 mm in diameter. The formats in which AA batteries are available include alkaline, saline, long-life lithium and rechargeable batteries of various capacities.

AA alkaline batteries have a storage life of around 6 years, while AA lithium equivalents last up to 9 years before use. Rechargeable AA batteries are now available in NiMH with capacities up to 2850 mAh, and are also available in the new "pre-charged" technology that lets you use them straight out of the box.
