Everything about Aaa Battery totally explained
» "AAA battery" may also be an abbreviation for "antiaircraft artillery battery"
An
AAA battery (pronounced "triple A") is a dry cell-type battery commonly used in portable electronic devices. It is also classified as
LR03 (
IEC),
24A (
ANSI/
NEDA),
R03,
MN2400,
AM4,
UM4,
HP16, or
micro. As an AAA battery is composed of a single chamber, it's more correctly referred to as a
cell. Technically, a battery is a collection of cells working together, such as in a car battery. The more common term "battery" will be used throughout the rest of this article.
An AAA battery measures 44.5
mm in length and 10.5 mm in diameter.
Alkaline AAA batteries weigh around 11.5
gram each, while
lithium AAAs weigh about 7.6 g, and rechargeable
NiMH AAAs typically weigh 14-15 g. The nominal voltage of alkaline and lithium AAAs is 1.5
V, while that of NiMH or NiCd cells is 1.2 V. The capacity of alkaline AAAs is typically 900 to 1,155
mA·
h (3240 to 4158
coulombs). Modern NiMH batteries of this size can store up to about 1000 mAh.
AAA batteries are commonly used in small electronic devices, such as TV remote controls, MP3-players and digital cameras. Devices that require the same voltage, but have a higher current draw, are often designed to use larger batteries such as the
AA battery type. AA batteries have about three times the capacity of AAA batteries. However, with the increasing efficiency and miniaturization of modern electronics, many devices which previously were designed for AA batteries—remote controls, computer mice, and keyboards—are being replaced by models that accept AAA cells.
Recent charge variants include AAA cells with embedded circuity —
USBCELL with built-in charger and folding
USB connector within the AAA format, enabling the battery to be charged by plugging into a USB port without a charger.
