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 rechargeable NiMH batteries. The typical voltage for these batteries is 1.5 V, while rechargeable batteries typically provide 1.2 V. Newer AA lithium batteries offer much higher capacity for 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. The ANSI and IEC battery nomenclature gives several designations for cells of this size, depending on the cell characteristics and chemistry. Each AA battery is 51 mm long and 14 mm in diameter. The formats in which AA batteries are available are: alkaline batteries, saline batteries, long-life lithium batteries and rechargeable batteries of different capacities. AA alkaline batteries have a shelf life of about 6 years, while the equivalent AA lithium batteries 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 from the package.

It may seem impossible, but if you place your order before 3pm you will receive it the very next day (on business days).

Product tabs refer to a user interface design pattern commonly used on e-commerce websites and product pages to organize and present various types of information about a product. Instead of overwhelming users with a long, single-page description, product tabs help break down information into manageable sections, each accessible through a tab. Each tab typically contains specific details or features of the product.
