Mignon (battery)

from Wikipedia, the free encyclopedia
Three mignon cells

Mignon , mignon cell , AA , AA cell or IEC size R6 are common names for a standardized, widespread size of a battery cell . The name Mignon comes from French and means “cute” there. These are cylindrical round cells with a diameter of 13.5 mm to 14.5 mm and a height of 49.2 mm to 50.5 mm. Only the two maximum values ​​are mentioned in the IEC standard. This results in a volume of approximately 7.5 cm³ to 8.0 cm³.

Mignon cells are produced with different electrochemical systems, which can differ significantly in nominal voltage , capacity and load capacity. The capacities of AA batteries are in the range of approx. 0.8  Ah to 3 Ah. B. 1.9 Ah to 2.5 Ah. Depending on the system, other, often manufacturer-specific terms are used for non-rechargeable and rechargeable mignon cells.

Due to the low cell voltage of usually 1.2  V to 1.5 V, several cells are usually interconnected to form a battery in devices.

AA batteries are primarily used in small, often portable, electrical and electronic devices. Examples are Cordless phones , cameras , toys , electronic flash units , flashlights , bicycle lamps , electronic alarm clock and remote controls . Although the electrical capacity of mignon cells is rather unsatisfactory for some applications, they are often used because they can be connected in series in a very space-saving manner to generate higher voltages, such as B. for microelectronics are necessary to generate. A 9-volt block is only more economical if a low electrical capacity is sufficient . The fact that Mignon batteries are available almost everywhere speaks in favor of their use.

Lithium-ion batteries are rarely offered individually, but mostly as a battery pack made up of several cells with integrated overcharge and discharge protection (protected). This prevents damage to the battery when discharging and charging.
