Li-ion battery in accordance with zoning, that is, two kinds of industrial and civil, industrial, and generally not less 18650 are generally laptop battery used for multi-polymer batteries, polymer batteries because of the shape of a good control, 18650 is a cylindrical, relatively speaking, is not good control of shape, and polymer batteries to carry light weight, so in military technology, space science and technology, oil drilling, etc. The use of polymer-based batteries, notebook batteries using polymer present as I know X300 series, and Apple and Toshiba that thin air of the machine, but also for shapes and light. Phone using a low-capacity polymer batteries, the relatively X300 battery power density of polymer batteries, but the latter's 1 / 3 cottage mobile phone battery in order to emphasize its durable, saying that there are more than 1000 amh battery capacity, the actual are not using a polymer batteries, but lithium batteries 103450 flat, X60t 8 cores used in the capacity of 103.45 thousand batteries had reached 2000mah, X41T there are also 1900MAH, therefore, the real polymer batteries, currently used in a notebook is the unit of 08K8214 energy density in the largest.
Manufacturers in the production of the same group of cells when the battery discharge test based on the performance of classification, ABCD is divided into four categories (Sanyo distinction, as this way the distinction between Sanyo and Panasonic has actually become the industry standard), A = 2000MAH , B = 2200MAH, C = 2400MAH D = 2600MAH, the battery on the distinction between marked with ABCD code, and then at the same time shielding gas in the battery cover to distinguish color (when the battery will discharge gas, the battery positive to have a protective cover, When the battery is deflated to a certain amount of time, that is soon to meet the design life of the time, the gas would be to open the lid to the top, so that the battery off road), this is the source of ABCD, as Sanyo and Panasonic's strength, this is also On the difference between the industry has become the default mode. Of course, this by the production technology limits are to stop the original 2400mah Sanyo batteries internal material composition in favor of new material formulations, therefore, the current production of 2000-2600mah Sanyo's batteries, in fact the same production line different quality products.
So, we often see what those who claim to what is used with an ultra-AA batteries compatible with the 08K8195 battery level what does that mean? In fact, purely a propaganda tool, Take the Sanyo to examples of each of the 18650-capacity batteries is very easy to distinguish ways of looking at the color of the battery cover to protect gas will know the capacity size. Sanyo battery assembly plants provided by the batteries to get after the matching assembly, thus matching the first (mainly the resistance of the pair) and then assembled, in this part inside the battery manufacturers and battery pack manufacturers do not distinguish between What is the so-called A + +. Then, on the market a new 2600mah batteries source of what is it? One is a real battery assembly factory inventories, that is, a certain number of the remaining tailings batteries, battery assembly plants in order to optimize the quality of the battery is generally refuse to use the residual tailings added a new batch of batteries inside the engaged in production; the second, that is, pre-production testing process, I found a variety of factors, does not fulfill the anti-2600mah batteries, but its capacity is significantly higher than the 2400mah batteries. Outside of these two 08K8193 batteries is a major source of sales of new 2600mah. Therefore, this so-called A + + what the stuff is completely merchants own standards, there is no basis. Moreover, the battery capacity and the English alphabetical order the contrary, B-level is the 2200mah batteries, which is frequently used Chinese-made notebook 4400MAH origin, and the price cheap and the most mature.
From the material point of view, batteries is the rare-earth + metal + precious metals, several major battery manufacturers have been imported from China Rare Earth (RE primary production in China), because of rare earth mineral is symbiotic, so even if there is another sophisticated purification techniques, each times of production materials are weak differences in the composition (mainly impurities), while the key materials - cobalt oxide also has its own characteristics, there is weak due to the radioactive cobalt oxide, and then there is the half-life, while impurities are particularly sensitive, then, each time produced batteries, made of a different origin of the rare earth materials, the quality vary, a slight difference in impurities enough to affect the lithium cobalt oxide lattice and stability, which is produced by the same group of batteries, manufacturers must be sub - capacity to identify the truth, and the same desktop machine using 08K8192 the memory, CPU frequency identification is to use the same way.
