Cell phone battery wounding experts teach you how to identify the authenticity

Lead: with the mobile phone has increasingly become an important communication tool in our life, the security problem of mobile phone battery is also more and more attention. Not long ago, the China Consumer Association issued a consumer warning: fake battery is the culprit causing mobile phone consumer wounding accident. Enthusiastic audience Miss Li, recently encountered such a situation.

Text: half a month ago, Ms. Lee bought a new battery, the first charge on the explosion occurred, which can be scared of her.

Miss Li: when you buy a battery, people say it is a real battery, the price is not cheap, more than and 100 dollars, I bought a block of two. When the explosion, thanks to the charger is filled with electricity, if the phone directly charged, the phone had to burst the bad! Later, I took another battery to detect, found to be false battery.

Text: for mobile phone consumption accident constantly, the day before, Chinese cloth Consumer Association consumer alert, stressed that the fake battery is easy to cause accident, consumers must be to the regular store to buy genuine goods at a fair price of goods. Some consumers can say, even if the true and false two batteries put together, they are difficult to distinguish.

Miss Li: in fact, when I buy the inferior battery, from the outside to watch, but also can not see is false, with the only know, but in case I am on the phone, the explosion, the consequences are too serious. It's terrible to think about it!

Abstract: in fact, the battery is not difficult to distinguish between true and false, the researchers China CTTL told reporters, first look at the price of the battery to distinguish between true and false, false battery price is low, generally tens of dollars, the second is to look at the packaging and anti-counterfeit label.

NOKIA staff: look at the anti-counterfeiting label, the general battery should have a security label.

Text: you see these two batteries, although there are security targets, but the left side of the battery is a clear three-dimensional security image, the right side of the fake battery, the label is a graphic design, there is no portrait. When the researchers took the battery apart, the difference was even greater.

Lab researcher: now I'm taking the battery after it opens. This is the old battery after the opening of the skin. It uses the material is relatively poor, a tear on the broken. This is a true, it uses the layers are more uniform. Another difference is that there is a protective circuit in the real battery. And there's nothing inside.

In addition, the regular lithium battery core is mostly used in light aluminum material, strong impact resistance, in case of an accident, there is pressure relief ability. The fake battery, the outer wall is often thicker steel plate, feel more heavy, although it looks neat, but if an accident, greater lethality. It is understood that the current state of the mobile phone battery life is not clearly defined, but most of the lithium battery can charge about one thousand times, the use of normal, about two or three years to replace the.
