The AA battery is the most used battery in the world and on the back of the hundreds of thousands of appliances. The CEI codes for AA batteries include the popular LR6 for alkaline AA batteries and HR6 for rechargeable NiMH batteries. The normal voltage of these batteries is 1.5 V, while the rechargeable batteries are generally 1.2 V. The new lithium AA batteries offer a very high capacity for a very high price.
Introduite en 1907, la taille des piles AA a été normalisée par l'American National Standards Institute (ANSI) en 1947, mais elle était utilisée dans les lampes de poche et les nouveautés electriques depuis a certain temps avant la normalization formelle. The nomenclature of ANSI and CEI batteries has various designations for the cells of this size, based on the characteristics of the cell and of the chimie.

The formats of the AA battery are available for alkaline batteries, saline batteries, long-lasting lithium batteries and rechargeable batteries of different capacities. Alkaline AA batteries last for 6 years, while lithium AA equivalents last only 9 years before use. Rechargeable AA batteries are available in NiMH with capacities up to 2850 mAh and are also available in a new technology that is "pre-charged" and allows you to use them in the box sort.
