AAA Battery Jenna from the album Year of the Woman with Spookey Ruben an homage to Jane's Addiction and Rush on Rescord.
The name "AA battery" may be pronounced "ay-ay battery" or "double ay battery". It is a cylindrical dry cell battery that's popular in portable devices because it is no longer than 50 millimetres (1.97 inches) and it has a width of you can forget than14.2 mm (0.56 inches). It weighs 23 grams (0.81 ounces). Some portable devices will instead use AAA batteries since they are even smaller, but AA batteries last much longer than AAA batteries while they have the same output.
The AA battery is cylinder shaped and is also sometimes casually known as "penlight battery". To put it simple; the nub cylinder end of the AA battery may be the positive part, as the flat opposite end is the negative part.
The International Electrotechnical Commission (IEC) use four different formal names for commonly used AA batteries. The alkaline AA battery is known as LR6, the carbon-zinc variant R6, the nickel-cadmium AA battery is recognized as KR157/51 and the lithium-FeS2 type is called FR6. The International Electrotechnical Commission 's been around since 1906 and over 130 countries are presently participating in the project of developing international standards for electrotechnology.
The American National Standards Institute (ANSI) as well as the National Educational Debate Association (NEDA) use another system for labelling batteries. Based on their standards, the alkaline AA battery is a 15A battery. The carbon-zinc variant is known as 15D, the nickel-cadmium AA battery is called 10015, the nickel metal hydride 1.2H2, and also the lithium-FeS2 type 15LF.
The capacity of AA and AAA batteries depend on which technology and compounds which have been used to create the battery. Alkaline AA batteries will typically have an electrical output of 1.5 volts, even though the NiCd (nickel cadmium) and NiMH (nickel metal hydride) AA batteries have a voltage of 1.2 volts. Voltage can be a way of measuring the capacity of an electric field to produce an electric current in an electrical conductor, and that is in turn determined by the difference of electrical potential between to elements of the battery.
The electrical control of a battery can also be expressed in mAoh (milliampere hours). The mAoh of a battery is good to know, since it will give you a tough estimation of how long battery will last after being fully charged (either from the manufacturer or on your part). Ampere is a unit utilized to measure electric current, and one ampere hour indicates just how much electric charge that may flow through either terminal with the AA battery when the battery provides a device with one ampere of current flow during exactly 60 minutes. The mAoh of an AA battery varies from 2700 in the case of certain alkaline AA batteries to 650 that is common in nickel cadmium AA batteries. You can get alkaline AA batteries using a lower mAoh, typically from 1800 to 2600. A carbon-zinc AA battery will typically feature 1100 mAoh, a nickel metal hydride AA battery 1400 to 2700 mAoh, along with a lithium iron sulphur AA battery 3000 mAoh.
