Formal and informal battery battery biggest difference - protection
Here refers to the regular battery: cell phone manufacturers original batteries and battery domestic brands, their products are in line with the national introduction of the national standard on lithium batteries, in the raw materials, design, manufacture, test, monitor the quality control procedures are set in security have the greatest guarantee.
Instead of regular batteries include: all kinds of counterfeit batteries and no relevant production licenses the production of battery manufacturers. GATEWAY NX7000 battery UNIWILL 258-4S4400-S1P1 Battery TOSHIBA PA3307U-1BRS Battery TOSHIBA PA3383U-1BRS Battery
Normal cells have built-in protection devices, commonly known as the protection board, the board's role to protect a very large, general overheating, overvoltage and overcurrent protection. Protection board from the controller chip (equivalent to testing and orders of the commander), and MOS tube (effect of tube length, the equivalent of actors), is detected when the control chip over-voltage over-current and other anomalies, they will give directions, so that immediately cut off the power MOS tube to protect the battery. And a little further advanced battery protection board will be together on the basis of an over-current over-temperature fuse, even if the failure of the protection board will promptly cut off the power to protect the safety of users, equivalent to double the insurance. At present, the neighboring countries over there in the forefront of Japan, has begun to formulate a bill will force manufacturers add second layer of protection for the battery.
Informal battery, then cut corners in a variety of links, most likely at the cost of these protective devices removed or is considered a more simple way to achieve such a result would create a huge security risk.

Battery casing material is very important - steel / iron shell is killer
Current battery casing material generally have steel / iron, aluminum, film of several materials, and if the explosion of the steel / iron shell of explosive power could be fatal.
