AAA Batteries

A AAA battery (pronounced "triple A") is a (((dry cell-type))) battery commonly used in portable electronic devices. It is also classified as LR03 (IEC), 24A (ANSI/NEDA), R03, RX03, MN2400, AM4, UM4, HP16, or micro. As a AAA battery is composed of a single chamber, it may also be referred to as a cell.

A AAA battery measures 44.5 mm in length and 10.5 mm in diameter. Alkaline AAA batteries weigh around 11.5 gram each, while lithium AAAs weigh about 7.6 g, and rechargeable NiMH AAAs typically weigh 14-15 g. The nominal voltage of alkaline and lithium AAAs is 1.5 V, while that of NiMH or NiCd cells is 1.2 V. The capacity of alkaline AAAs is typically 900 to 1,155 mA·h (3240 to 4158 coulombs).

NiMH AAA Batteries

AAA batteries are commonly used in small electronic devices, such as TV remote controls, MP3-players and digital cameras. Devices that require the same voltage, but have a higher current draw, are often designed to use larger batteries such as the AA battery type. AA batteries have about three times the capacity of AAA batteries. However, with the increasing efficiency and miniaturization of modern electronics, many devices which previously were designed for AA batteries—remote controls, computer mice, and keyboards—are being replaced by models that accept AAA cells.
