A pack of AAAA batteries.
The *AAAA* battery (usually read as /quadruple-A/) 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 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*.

Collage of images showing the opening of a 9-volt battery to reveal six
LR61 cells, which are similar to AAAA cells.
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. These batteries are not as popular as AAA or AA
type batteries, and consequently are not as commonly available.
Some models of alkaline nine-volt battery may consist of a bundle of six
LR61 cells inside,^ connected together by welded tabs. These cells are
somewhat similar to AAAA cells and can be used in their stead in some
devices, even though they are 3.5 millimetres (0.14 in) shorter. These
cells are often unmarked so special care must be taken with polarity.
