A Duracell AA alkaline battery

Rechargable AA batteries

An AA battery (IPA pronunciation: [eɪ eɪ] or [ˈdʌbl̩ eɪ]) is a dry cell-type battery commonly used in portable electronic devices. An AA battery measures 51mm in length (50.1mm without the button terminal), 13.5–14.5mm in diameter^[1], and generally weighs (depending upon materials) approximately 23g (1.97×0.56 inches and 0.81 ounces).

As an AA battery is composed of a single chamber, it is 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.

The nominal output voltage of single-use AA batteries is 1.5 volts, while NiCD (Nickel Cadmium) rechargeable batteries have a nominal voltage of 1.2V. Specialty batteries based on exotic chemistries can run as high as 1.6V under load ^[2]. The voltage of a AA battery is the same as a AAA battery, C cell or D cell. AA batteries, however, provide power for a longer period than AAA batteries, because their larger size allows them to store more electrolyte. C and D cells, being larger still, can be expected to last longer again. A nominal is a word or a group of words that functions as a noun, i. ...

Primary (non-rechargeable) zinc-carbon AA batteries of 400–900 milliamp-hours capacity are common. Zinc-chloride batteries of 1000 to 1500 mAh are often sold as "long life" or "heavy duty". Alkaline batteries from 1700 mAh to almost 3000 mAh cost a little more, but last proportionally longer. Zinc-carbon batteries of different sizes. ...

Single-use lithium batteries are also available for high demand devices such as digital cameras, where their high cost is offset by longer running time between battery changes. As of 2007, the only 1.5V lithium AA is manufactured by Eveready, although AA sized batteries with different nominal voltages are available from others. These should only be used in devices rated for the higher voltage. CR2032 lithium battery Lithium batteries are primary batteries that have lithium metal anodes. ...

Rechargable AA Batteries

The capacity of rechargeable AA batteries varies with the technology used. Nickel-cadmium (NiCd or NiCad) AAs with a capacity of 650 to 800 mAh are commonly available, while 800 to 1000 mAh AA types are rarer and more expensive. Nickel metal hydride (NiMH) AAs are also available in various capacities ranging from 1400 to 2900 mAh.^{[citation needed]} The nickel-cadmium battery (commonly abbreviated NiCd and pronounced nye-cad) is a popular type of rechargeable battery for portable electronics and toys using the metals nickel (Ni) and cadmium (Cd) as the active chemicals. ... This article does not cite any references or sources. ...

The older NiCd battery chemistry can supply a higher current than typical NiMHs, so NiCds are commonly used to power model cars or other relatively high-current-draw devices. New NiMH AAs designed for high current applications are beginning to become available. These use different construction and have lower capacity (1400–1600 mAh) than the highest capacity NiMH batteries. Electric current is the flow (movement) of electric charge. ...

Recently, AA-sized batteries have been introduced in rechargeable Li-ion chemistry. These batteries also do not supply voltage in the 1.2–1.5 V range and are thus not true AAs. Li-Ion Camera Battery Lithium ion batteries (or Li-ion) have become very common and dropped in price recently. ...

A lot of rechargable AA batteries that are sold under various brands are actually made by Sony and have just been packaged with that brand's cell-cover. The batteries made by Sony have a 'HR' embossed on the bottom of the batteries and are made in Japan or China. [1]

The insides of a ZnC battery

The common zinc-carbon or zinc-chloride AA battery consists of a graphite or plastic rod in the center, paper, electrolytes, a zinc outer shell, and a plastic cover. There is also a pressure valve at the bottom to prevent explosions. However, the pressure valves generally will not prevent leakage or catastrophic failure of the shell if the battery is exposed to fire or extreme heat. Graphite (named by Abraham Gottlob Werner in 1789 from the Greek γραφειν (graphein): to draw/write, for its use in pencils) is one of the allotropes of carbon. ... General Name, Symbol, Number zinc, Zn, 30 Chemical series transition metals Group, Period, Block 12, 4, d Appearance bluish pale gray Standard atomic weight 65. ...

If a Zn-C or Zn-Cl battery is discharged too far then corrosion of the cathode, which is the zinc shell, can occur. If this becomes corroded enough, a breach in the shell can allow electrolyte to leak out. This is a common cause of damage to battery-powered appliances which are left unattended for long periods with batteries inside. The electrolyte can also cause minor skin damage, and should be kept away from eyes, and not ingested.
