Internationally the IEC designated it as LR6 (alkaline), R6 (carbon-zinc), KR157/51 (nickel-cadmium), HR6 (nickel-metal-hydride), and FR6 (lithium-iron-disulfide). Other names include MN1500 and HP7. In China it is known as the #5 battery. In Germany it is known colloquially as Mignon. An AA battery is composed of a single electrochemical cell.
