The AA battery (or double-A battery) is a standard size single cell cylindrical dry battery. The IEC 60086 system calls the size R6, and ANSI C18 calls it 15. [1] It is named UM-3 by JIS of Japan. [2] Historically, it is known as D14 (hearing aid battery), [3] U12 – later U7 (standard cell), or HP7 (for zinc chloride 'high power' version) in official documentation in the United Kingdom, or a pen cell. [4] NiMH and lithium-ion AA/14500 cells can supply most of their capacity even when under a high current drain (0.5A and higher), unlike alkaline and zinc-chloride ("Heavy Duty"/"Super Heavy Duty") cells which drop to a small fraction of their low current capacity before even reaching 1 C.

We’ve touched on the dangers of mistreating certain high-drain rechargeables - particularly li-ion batteries - in previous sections, but what about regular disposable AA batteries? Can they explode or rupture in dangerous ways? Well, while it’s very rare indeed for AA batteries to explode in typical day-to-day use, ruptures or even small explosions aren’t impossible. Are best bought in multiples of the amount needed for the device in question, so there’s always a replacement set charged and ready to go Bergveld, H; Kruijt, W; Notten, P (February 1999).

Bibcode: 1999JPS....77..143B. doi: 10.1016/S0378-7753(98)00188-8. Primary (non-rechargeable) zinc–carbon ( dry cell) AA batteries have around 400–900 milliampere hours capacity, with measured capacity highly dependent on test conditions, duty cycle, and cut-off voltage. Zinc–carbon batteries are usually marketed as "general purpose" batteries. Zinc-chloride batteries store around 1,000 to 1,500mAh are often sold as "heavy duty" or "super heavy duty". Alkaline batteries from 1,700mAh to 2,850mAh cost more than zinc-chloride batteries, but hold additional charge. AA size alkaline batteries are termed as LR06 by IEC, and AM-3 by JIS.

the standard nominal voltage for batteries of this size ( AA 1.5V batteries are the most common and widely available versions, particularly of alkaline and zinc-carbon cells) The application you’re using the batteries for, and the environment/conditions you’re using them in both reasonably common nominal voltages in batteries intended for use in high-drain applications (lithium cells are commonly sold as 3.6V AA lithium batteries) Lithium Iron Disulfide Handbook and Application Manual, Version LI4.04, Energizer Battery Manufacturing Inc. Introduced in 1907 by The American Ever Ready Company, [5] [ third-party source needed] the AA battery size was standardized by the American National Standards Institute (ANSI) in 1947, but it had been in use in flashlights and electrical novelties before formal standardization. ANSI and IEC battery nomenclature gives several designations for cells in this size, depending on cell features and chemistry. Before being called AA batteries, they were commonly called Z batteries, as the ones produced by the Burgess Battery Company were sold as "Number Z" (meant to indicate them being smaller than the "Number 1", which was similar in size to a modern C battery). [ citation needed] Due to their popularity in small flashlights, they are often called "penlight batteries".An AA cell measures 49.2–50.5mm (1.94–1.99in) in length, including the button terminal—and 13.5–14.5mm (0.53–0.57in) in diameter. The positive terminal button should be a minimum 1mm high and a maximum 5.5mm in diameter, the flat negative terminal should be a minimum diameter of 7mm. [1] 14500 Lithium Batteries are longer if they feature a protection circuit up to 53mm.

By 2023, several brands of 1.5V Li-ion rechargeable batteries in both AA and AAA sizes (with voltage converting circuitry in even the small AAA casing) were available. They use various charging methods, without the special Kentli ring third electrode. Some have special chargers—a charger for a 1.2V cell will not provide sufficient voltage—but do not use a third electrode. [21] Others have a USB port built into the cell itself. [22] NiZn [ edit ] There are various kinds of batteries in use today. The main difference between them is the technology they use, the amount of power they can supply and whether they are rechargeable. Dry-cell batteries, which include alkaline, lithium and NiMH rechargeable AA batteries, are allowed in carry-on luggage (both inside devices and as spares)Won’t typically last very long in high-drain devices such as digital cameras; they can’t output their full power fast enough to cope with the demands of high-drain electronics especially well If you’re storing a mixture of brand new and partially used batteries, keep them separate and clearly labelled Alkaline AA cells have a weight of roughly 23g (0.81oz), [6] lithium AA cells around 15g (0.53oz), [7] and rechargeable Ni-MH cells around 31g (1.1oz).

Alkaline: Alkaline batteries are the standard batteries we all know and love. They are available in all standard sizes and should be available for sale in most stores. Alkaline batteries aren't suited for frequent use in digital cameras. They last for only a few shots before being completely drained. This is an expensive solution if you intend to use your camera on a regular basis. However they should be fine for use in an emergency when your rechargeable batteries have run out... Calculating and comparing expected AA battery life is an inexact science - or rather, it’s one with so many possible variables that it doesn’t always appear a like-for-like comparison once you start weighing up different cell chemistries for different usage scenarios. If you’re ever faced with a badly leaking, ruptured or exploded alkaline AA battery, the best procedure is to immediately and carefully wash all traces of ejected material off your skin. Once this has been done, any traces of this remaining lye material should be neutralised with a household acid such as vinegar or lemon juice - but only do so after removing as much material as possible with water, otherwise, an exothermic chemical reaction can occur, generating more heat.Never store rechargeable batteries inside a charger, and never attempt to recharge a battery that’s not designed to do so
