An AAAA battery is 42.5 mm long and 8.3 mm in diameter, weighing
around 6.5 grams. Output of alkaline batteries in this size is 1.5 volts,
625 mA·h.
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.
This battery size is most often used in devices requiring small batteries
such as laser pointers, LED penlights, powered computer styli, and small
headphone amplifiers. These batteries are not as popular as AAA or AA type
batteries, and can be quite hard to find. Some (not all) brands of alkaline
9 volt batteries have a bundle of six AAAA cells inside, connected together
by welded tabs.[1]
The AAAA is also available in a PCB Tagged version, 8.4mm x 66mm,
weighing 10.5g. These tagged AAAA batteries are NiMh rechargeable as such
will charge from the PCB they are soldered onto.

Shelf
life of AAAA Alkaline
- User of AAAA Alkaline batteries will generally experience shorter
shelf life than that of counterpart batteries in the same product line.
(If compared to AAA, AA etc.)
- Also AAAA batteries once used (e² brand for example) begin corroding
at the terminals particularly the positive end, which may damage your
devices if not checked periodically. When the corrosion characteristics
are compared to AAA or larger batteries they simply don't corrode as
quickly, if at all. The reason for this is not clear but it suspected
that it has to do with the thinner packaging walls, making it
susceptible to corrosion leaks.
