AA battery

Mignon Mignon cell, AA, AA - cell or R6 are common names for a standardized, widely used size of a battery cell or battery cell (not to be confused with Micro or AAA). The term " Mignon " comes from the French and means there " cute ". It involves cylindrical round cells with diameters of 13,5 to 14,5 mm and a height from 49.2 to 50.5 mm (according to IEC standard). This results in a volume of about 7.5 to 8.0 cm ³ yields. AA batteries are manufactured with different electrochemical systems, which can be clearly different from the rated voltage, capacity and resilience. The capacity of AA batteries are in the range of about 400-2900 mAh, consistently are, for example in 2010, 2000 to 2500 mAh, 2011, this number rose to 2850 mAh already. Depending on the system more often vendor-specific names for non-rechargeable and rechargeable AA batteries are used.

Due to the low cell voltage of 1.2 to 1.5 volts, a plurality of cells are usually connected together to form a battery. Colloquially, a single cell is often called a "battery."

Type overview

AA batteries are mainly used in small, often portable, electrical and electronic equipment. Examples are mobile phones, cameras, PDAs, computer mice, Walkman, CD players, toys, flashlights, calculators, watches and remote controls.

Although the electrical capacity of AA cells is rather unsatisfactory for some applications, they often get so used because they can be switched very limited space in series to produce higher voltages, as they are necessary for microelectronics, for example. If only a small electric capacity sufficient to provide a 9-volt block is more economical.

Lithium- ion batteries in this size are also offered with integrated overflow and discharge protection. This damage to the batteries during discharging and loading can be prevented.
