AAAA Battery
Encyclopedia
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 producing 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.

s. 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 millimetre (0.137795275590551 in) shorter. These cells are often unmarked so special care must be taken with polarity.
Battery (electricity)
An electrical battery is one or more electrochemical cells that convert stored chemical energy into electrical energy. Since the invention of the first battery in 1800 by Alessandro Volta and especially since the technically improved Daniell cell in 1836, batteries have become a common power...
