AAAA battery

AAAA battery

The AAAA battery (usually read as "quadruple-A") is 42.5 mm long and 8.3 mm in diameter, weighing around 6.5 g. This battery is also classified as LR8D425 (IEC) and 25A (ANSI/NEDA). The battery is also known by its Duracell type number MN2500 or MX2500 and Energizer type number E96.

Uses

This battery size is most often used in devices requiring small batteries, such as laser pointers, LED penlights, powered computer styli, glucose meters, and small headphone amplifiers. These batteries are not as popular as AAA or AA type batteries, and can be quite hard to find. The average AAAA alkaline cell has approximately a 595 mAh capacity. A typical 9 volt battery consists of a bundle of six AAAA cells inside, connected together by welded tabs. [cite web
