An AA battery (pronounced 'double a' English pronunciation: /dbl e/) is a dry cell-type battery commonly used in portable electronic devices. The AA battery type was standardized by ANSI in 1947, and is designated E91 by DIN and AM3 by JIS. Internationally the IEC designated it as LR6 (alkaline), R6 (carbon-zinc), KR157/51 (nickel-cadmium), HR6 (nickel-metal-hydride), and FR6 (lithium-iron-disulfide). Other names include MN1500 and HP7. In China it is well know as the #5 battery. In Germany it is known colloquially as Mignon. An AA battery is composed connected with a single electrochemical solar cell. 4.5-Volt, D, C, AA, AAA, 9-Volt, SR41/AG3, SR44/AG13 cells An AA battery measures 51 mm in length (50.1 mm without the button terminal), 13.5-14.5 mm in diameter, (1.97i0.56 inches). Traditional alkaline AA batteries have mass of roughly 23 g (0.81 oz), Lithium AA batteries have mass around 15 g (0.5 oz), and rechargeable NiMH batteries have mass about 31 g (1.1 oz). The nominal output voltage of single-use AA batteries is .5 volts, while NiCd and NiMH rechargeable batteries have a nominal voltage of 2.2 V. Specialty batteries based on more unusual chemistries can run within the voltage up to as 1 particular.6 V under load. The voltage of an AA battery is pertaining to as an AAA battery, C cell or D cell. AA batteries, however, provide power for a longer period than AAA batteries, because their larger size allows the store a greater mass of anode material which is consumed precisely as it does electrical work. C and D cells, being larger, are longer lasting still; to be a rough guide, the capacity of a cell scales linearly with its mass. Primary (non-rechargeable) zinc-carbon AA batteries of 400-900 milliamp-hours capacity are commonly made using Leclanchi cell technology. 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. Single-use (ie. non-rechargeable) lithium batteries are also available for prime demand devices such as digital cameras, where their high expense is offset by longer running time between battery differences. As of 2008, the only 1.5 V lithium AA called 'Ultimate Lithium', is manufactured by Energizer, although AA-sized batteries numerous nominal voltages are you can purchase others. These should only be utilized in devices rated for the higher voltage. Inside a ZnC battery The formerly common zinc-carbon or zinc-chloride AA battery consists of an graphite rod in the center forming an electrode, an anode/electrolyte mix consisting mainly of manganese oxide, a zinc shell which serves as the cathode, and a paper, plastic or steel cover. See Zinc-carbon battery power. There is sometimes a pressure valve at the underside to prevent explosions. However, this generally will not prevent leakage or catastrophic failure for the shell when the battery is exposed to fire or cause problems. If a Zn-C or Zn-Cl battery is discharged too far, corrosion belonging to the cathode, which is the zinc shell, happen. If it gets corroded enough, a breach in the shell can allow electrolyte to leak launched. This is the same cause of injury to battery-powered appliances usually are left unattended for extended periods with batteries inside. The electrolyte can also cause minor skin damage, and end up being kept not in the eyes, with out ingested. Inside an alkaline battery More common today than the lower cost ZnC batteries are alkaline cells. Different variants exist, offering automobile to 3 x the capacity of ZnC cells. Compared to zinc chloride as the electrolyte, potassium hydroxide is used. We hope the article helped recognize and information about an AA electric.
