NiMH AAA batteries
D, C, AA, *AAA*, AAAA, 9-Volt batteries
An *AAA* or *triple-A battery* is a standard size of dry cell battery
commonly used in portable electronic devices. A carbon-zinc battery in this
size is designated by IEC as "R03", by ANSI C18.1 as "24", by old JIS
standard as "UM 4", and by other manufacturer and national standard
designations that vary depending on the cell chemistry.
A triple-A battery is a single cell and measures 44.5 mm in length and 10.5
mm in diameter. Alkaline AAA batteries weigh around 11.5 grams each, while
lithium AAAs weigh about 7.6 g. Rechargeable nickelâmetal hydride
(NiMH) AAAs typically weigh 14â15 g.

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. With the increasing efficiency and
miniaturisation of modern electronics, many devices which previously were
designed for AA batteries (remote controls, and cordless computer mice and
keyboards, etc.) are being replaced by models that accept AAA cells.
As of 2007, AAA batteries accounted for 24% of alkaline primary battery
sales in the United States. In Japan as of 2011, 28% of alkaline primary
batteries sold were AAA. In Switzerland as of 2008, AAA batteries totalled
