The AAAA battery (usually read as quadruple-A) is 42.5 mm long and 8.3 mm in diameter, weighing around 6.5 g and producing 1.5 V. This battery is also classified as LR8D425 or LR61 (IEC) and 25A (ANSI/NEDA). The battery is also known by its Duracell type number MN2500 or MX2500 and Energizer type number E96.

Uses

Open 9-Volt 'transistor' battery showing five of six AAAA cells, as commonly used in medical equipment.

This battery size is most often used in devices requiring small batteries, such as laser pointers, LED penlights, powered computer styluses, 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. However, a typical alkaline 9 volt battery may consist of a bundle of six AAAA cells inside, connected together by welded tabs or small circuit boards. If disassembled, most 9 volt batteries can provide a supply of AAAA batteries.[citation needed] Carbon-zinc types use stacks of rectangular batteries instead of AAAAs. The average AAAA alkaline cell has approximately a 595 mAh capacity[citation needed]. The AAAA is also available in a PCB tagged version, 8.4mm x 66mm, weighing 10.5g. These tagged AAAA batteries are NiMH rechargeable, and as such will charge from the PCB power supply they are soldered onto.
