AAAA Battery
The AAAA battery (usually read as ''quadruple-A'') is 42.5 mm long and 8.3 mm in diameter. The alkaline cell weighs around 6.5 g and produces 1.5 V. This size battery is also classified as R8D425 (IEC) and 25 (ANSI/ NEDA). The alkaline battery in this size is also known by Duracell type number MN2500 or MX2500 and Energizer type number E96. History Energizer created the first AAAA battery in 1989, pressured by environmental initiatives to eliminate added mercury in batteries. Now most big battery manufactures (Energizer, Duracell), sell AAAA batteries. Types Uses This battery size is most often used in small devices such as laser pointers, LED penlights, powered computer styluses, glucose meters, and small headphone amplifiers, with Microsoft's Surface Pen the most prominent product taking AAAA batteries. These batteries are not as popular as AAA or AA type batteries, and consequently are not as commonly available. Some models of alkaline nine-volt battery ...

6 Most Common Battery Types-1
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler".

Battery Nomenclature
Standard battery nomenclature describes portable dry cell batteries that have physical dimensions and electrical characteristics interchangeable between manufacturers. The long history of disposable dry cells means that many manufacturer-specific and national standards were used to designate sizes, long before international standards were reached. Technical standards for battery sizes and types are set by standards organizations such as International Electrotechnical Commission (IEC) and American National Standards Institute (ANSI). Popular sizes are still referred to by old standard or manufacturer designations, and some non-systematic designations have been included in current international standards due to wide use. The complete nomenclature for the battery will fully specify the size, chemistry, terminal arrangements, and special characteristics of a battery. The same physically interchangeable cell size may have widely different characteristics; physical interchangeabil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VARTA
VARTA AG (; german: link=no, Vertrieb, Aufladung, Reparatur transportabler Akkumulatoren – ) is a German company manufacturing batteries for global automotive, industrial, and consumer markets. History VARTA was founded by Adolf Müller in 1887, and established in 1904 as a subsidiary of Accumulatoren-Fabrik AFA. After World War I, VARTA together with AFA was acquired by German industrialist Günther Quandt and Industrialist and VARTA CEO Dr. Carl Hermann Roderbourg. After World War II, most of the VARTA shares passed from Günther Quandt to his son, Herbert Quandt. The subsidiary in East Berlin was later occupied by the Soviet Union, and was named BAE Batterien. In 1977, VARTA AG's businesses were split up by Herbert Quandt; battery and plastics operations were retained in VARTA AG, but the pharmaceuticals and specialty chemical businesses were transferred to a new company called Altana, and the electrical business was spun off into a company called CEAG.

Nine-volt Battery
The nine-volt battery, or 9-volt battery, is an electric battery that supplies a nominal voltage of 9 volts. Actual voltage measures 7.2 to 9.6 volts, depending on battery chemistry. Batteries of various sizes and capacities are manufactured; a very common size is known as PP3, introduced for early transistor radios. The PP3 has a rectangular prism shape with rounded edges and two polarized snap connectors on the top. This type is commonly used for many applications including household uses such as smoke and gas detectors, clocks, and toys. The nine-volt PP3-size battery is commonly available in primary zinc-carbon and alkaline chemistry, in primary lithium iron disulfide and lithium manganese dioxide (sometimes designated CRV9 9-volt batteries supplied by a typical distributor: PP3 (or CRV9), PP6, PP7, and PP9 are the PP sizes; A10 and A29 the only other 9v types.), and in rechargeable form in nickel-cadmium (Ni–Cd), nickel-metal hydride (Ni–MH) and lithium-ion.

Headphone Amplifier
A headphone amplifier is a low-powered audio amplifier designed particularly to drive headphones worn on or in the ears, instead of loudspeakers in speaker enclosures. Most commonly, headphone amplifiers are found embedded in electronic devices that have a headphone jack, such as integrated amplifiers, portable music players (e.g., iPods), and televisions. However, standalone units are used, especially in audiophile markets and in professional audio applications, such as music studios. Headphone amplifiers are available in consumer-grade models used by hi-fi enthusiasts and audiophiles and professional audio models, which are used in recording studios. Consumer models Consumer headphone amplifiers are commercially available separate devices, sold to a niche audiophile market of hi-fi enthusiasts. These devices allow for higher possible volumes and superior current capacity compared to the smaller, less expensive headphone amplifiers that are used in most audio players. In t ...

Glucose Meters
A glucose meter, also referred to as a "glucometer", is a medical device for determining the approximate concentration of glucose in the blood. It can also be a strip of glucose paper dipped into a substance and measured to the glucose chart. It is a key element of glucose testing including home blood glucose monitoring (HBGM) by people with diabetes mellitus or hypoglycemia. A small drop of blood, obtained by pricking the skin with a lancet, is placed on a disposable test strip that the meter reads and uses to calculate the blood glucose level. The meter then displays the level in units of mg/dL or mmol/L. Since approximately 1980, a primary goal of the management of type 1 diabetes and type 2 diabetes mellitus has been achieving closer-to-normal levels of glucose in the blood for as much of the time as possible, guided by HBGM several times a day. The benefits include a reduction in the occurrence rate and severity of long-term complications from hyperglycemia as well as ...

Powered Computer Stylus
An active pen (also referred to as active stylus) is an input device that includes electronic components and allows users to write directly onto the display of a computing device such as a smartphone, tablet computer or ultrabook. The active pen marketplace has long been dominated by N-trig and Wacom, but newer firms Atmel and Synaptics also offer active pen designs. An active pen is generally larger and has more features than a stylus. Digital pens typically contain internal electronics and have features such as touch sensitivity, input buttons, memory, writing data transmission capabilities, and electronic erasers. The main difference between an active pen and the input device known as a passive stylus or passive pen is that although the latter can also be used to write directly onto the screen, it does not include electronics and thus lacks all of the features that are unique for an active pen: touch sensitivity, input buttons, etc. Active pen devices support most modern o ...
