An Introduction to AA Batteries

The name "AA battery" could be pronounced "ay-ay battery" or "double ay battery". It is a cylindrical dry cell battery that is popular in portable devices as it is no longer than 50 millimetres (1.97 inches) and possesses a width of forget about 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 even though they have the same output.

The AA battery is cylinder shaped and is sometimes casually referred to as a "penlight battery". To put it simple; the nub cylinder end from the AA battery is the positive part, while the flat opposite end is the negative part.

The International Electrotechnical Commission (IEC) use four different formal names for the most 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 named FR6. The International Electrotechnical Commission has existed since 1906 and over 130 countries are participating in the project of creating 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. In accordance with their standards, the alkaline AA battery can be a 15A battery. The carbon-zinc variant is named 15D, the nickel-cadmium AA battery is known as 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 that 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 possess a voltage of 1.2 volts. Voltage is a way of measuring the capacity of your electric field to make an electric current in an electrical conductor, and this is in turn determined by the real difference of electrical potential between to areas of the battery.

The electrical power over a battery can also be expressed in mAoh (milliampere hours). The mAoh of the battery is good to know, since it will give you a rough estimation of how long the battery will last after being fully charged (either through the manufacturer or on your side). Ampere is a unit accustomed to measure electric current, then 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 may get alkaline AA batteries having 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. - AAA Battery Jenna
