In a Primary Battery, the electrochemical process is irreversible i.e., once we utilize all its chemical energy, there is no way to reverse it. The basic classification of batteries consists of only two types Primary and Secondary. Technically, a battery consists of one or more cells, the basic electrochemical unit that is made up of electrodes (anode and cathode) and an electrolyte. What is a Battery? A Battery is an electrochemical device that converts chemical energy to electrical energy. A Brief Note on Batteries #īefore jumping into the AA vs AAA batteries comparison, let us take things slow and have a brief understanding of battery. Here, we will understand the basics of both AA and AA Batteries, find out their differences, and many more things.

In Japan as of 2011, 28% of alkaline primary batteries sold were AAA. With the increasing efficiency and miniaturization of modern electronics, many devices that previously were designed for AA batteries (remote controls, cordless computer mice and keyboards, etc.) are being replaced by models that accept AAA battery cells.Īs of 2007, AAA batteries accounted for 24% of alkaline primary battery sales in the United States. AA batteries have about three times the capacity of AAA batteries. 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 VS AAA BATTERIES SIZE TV
Rechargeable nickel–metal hydride (NiMH) AAA batteries typically weigh 14–15 g (0.49–0.53 oz).ĪAA batteries are most often used in small electronic devices, such as TV remote controls, MP3 players and digital cameras. Alkaline AAA batteries weigh around 11.5 grams (0.41 oz), while primary lithium AAA batteries weigh about 7.6 g (0.27 oz). The positive terminal has a maximum diameter of 3.8 mm (0.15 in) the flat negative terminal has a minimum diameter of 4.3 mm (0.17 in). Īn AAA battery is a single cell that measures 10.5 mm (0.41 in) in diameter and 44.5 mm (1.75 in) in length, including the positive terminal button, which is a minimum 0.8 mm (0.031 in). The size was first introduced by The American Ever Ready Company in 1911. A zinc–carbon 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.

One or more AAA batteries are commonly used in low-drain portable electronic devices. The AAA battery (or triple-A battery) is a standard size of dry cell battery.
