AAAA battery
The AAAA battery (or quadruple-A battery) is 42.5 mm long and 8.3 mm in diameter. The alkaline cell weighs around 6.5 g and produces 1.5 V. This size battery is also classified as R8D425 (IEC)[1] and 25 (ANSI/NEDA). The alkaline battery in this size is also known by Duracell type number MN2500 or MX2500 and Energizer type number E96.

Uses
[edit source]
This battery size is most often used in small devices such as laser pointers, LED penlights, powered computer styluses, glucose meters, and small headphone amplifiers, with Microsoft's Surface Pen the most prominent[citation needed] product taking AAAA batteries. These batteries are not as popular as AAA or AA type batteries, and are consequently not as commonly available in physical stores.
Some models of alkaline nine-volt battery contain six LR61 cells[4] connected by welded tabs. These cells are similar to AAAA cells and can be used in their place in some devices, even though they are 3.5 millimetres (0.14 in) shorter.
