We are in the market to replace laptop battery, it often to see what those who claim to what is used with an ultra-AA batteries compatible with the 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 batteries XPS M140 battery , Inspiron XPS M170 battery 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.

         On the resistance of the pair, the battery on the relationship between the good and bad, and if one had the same batteries C1295 , HD438 , D5318 , inside the battery parameters are almost identical in all aspects, then the battery will be able to give full play to the greatest advantage of these batteries, if one of these batteries in some of the parameters a and another a few batteries vary greatly, then the battery can play to its advantages at this time will receive its influence, and the barrel is the same principle to decide the capacity of this bucket is the bucket The lowest piece of wood to decide.

   Not here to use a professional terms, just simply say that a moment principle. We hope that readers can understand!
