The new year, Guangzhou, an explosion took place with the mobile phone of Laptop Battery deaths from injuries once more to alert the country more than 600 million mobile phone users, though it has denied media reports the origin of the explosion of cell phone or battery, but still a lot of people stepped up, "beware of poor quality cell phone batteries, cell phone-free variable 'grenade' "idea, in short sentence: the use of mobile phones to be careful.
The most deadly steel battery
Practitioners in the mobile phone industry, according to a person who for many years, currently the battery casing material generally have iron (steel), aluminum, film of several materials, and if an explosion blast steel battery could be fatal.
Aluminum shell in the hot overvoltage overcurrent situation would be inflated, but the relatively soft aluminum so that the characteristics of the battery is not easy to explode, expand to a certain extent it will open the next, the gas will come out. At this time despite the battery end of life, but will not explode, but pay attention to, run out of gas If you are experiencing high temperatures, will continue to burn or even explode.
The shell is used for original film and big brand batteries Sony VGP-BPS10 battery, is a relatively safe one, with the protection device, explosive probability is very low, even in the face unusual circumstances, will automatically cut off power supply, so that the battery can not be used, but it will not happen explosion.
Steel (steel) shell contrast to the above two kinds of battery manufacturing cost of the most expensive as it is more hard sharp, no flexibility, the battery internal explosion, the iron and steel debris will immediately exploded, with high slit people's skin, make mobile phone into a a small bomb, could be fatal.
Teach you to distinguish fake batteries
It is, at present the market of fake and shoddy battery there is a common problem: the battery inside the battery chip core components of poor quality, insufficient charge and discharge time is short, anti-sabotage poor performance, the marked discrepancies with the actual battery capacity.
The genuine mobile phone batteries generally have the following exterior features: battery Sony VGP-BPS9 battery label use of the second printing technology, in a certain light, and from the slope of view, part of the color bar code significantly more than in other parts of the black, and Mo Shangqu hand feel than other parts of slightly convex, many with original equipment batteries have this characteristic. In general, the superior performance of the cell phone battery, an internal over-current protection device, once the external short-circuit the phone, give rise to significant impact on current, the overcurrent protection device can automatically cut off the charging circuit in order to avoid cell phone batteries due to high current the impact of the phenomenon of the event of damage or burning. The bad battery is likely that there is no over-current protection device, so charging the battery after a long period, the battery shell may appear the phenomenon of boiling, the worst case, smoking behavior may occur. If the battery charge did not take long, hot phenomenon appeared, then the likelihood, the battery Sony VGP-BPS8 battery is defective.
The safe use of mobile phones
Try to use the original battery and original battery charger; Do not put the battery under high temperature environment, while avoiding direct sunlight in summer; in charging try not to call; Do not phone hung on the chest; as much as possible on the mobile phone bag ; phone encounter in the course in use of water, must immediately turn off the phone remove the battery power as soon as possible repair, or cell phone hair dryer drying moisture inside (only available heater), water erosion can also reduce the extent of board ; in a clean cell phone, dip a soft cloth can be used with low concentrations of dishwashing detergent and then with a soft cloth immersed in warm water, wring dry cleaning, pay attention Do not use other chemical Sony VGP-BPS5 battery reagents.
