Supplement to the method of authenticating mobile phone lithium battery

Check for abnormalities in charging. Generally, there should be an over-current protector inside the battery of a genuine mobile phone. In the case of excessive current caused by an external short circuit, the circuit will be automatically cut off to avoid burning or damaging the mobile phone; lithium-ion batteries also have an over-current protection circuit. , When the AC current is too large, it will automatically cut off the power supply, causing the battery to fail to charge. When the battery is normal, it can automatically return to the on state. If, during the charging process, we find that the battery is seriously heated or smoked, or even exploded, it means that the battery must be fake.

Look carefully at the anti-counterfeiting signs. For example, the word NOKIA hidden obliquely under the sticker is one of the tricks. Clear and flawless is the original product; dim and pale is a counterfeit product.

If you look closely, you may also find the name of the manufacturer. For example, for Motorola battery, its anti-counterfeiting trademark is diamond-shaped, and it can flash and have a three-dimensional effect no matter from any angle. Motorola, Original and printed clearly, are authentic. On the contrary, once the color is dim, the three-dimensional impression is insufficient, and the words are blurred, it may be fake.

With the help of special tools. Faced with more and more types of mobile phone batteries on the market, and counterfeit technology is becoming more and more sophisticated, some large companies are also constantly improving anti-counterfeiting technologies, such as the new Nokia’s mobile phone battery, which has a special logo on it. Processing requires a special prism to identify, and this prism is only available in Nokia. Therefore, with the improvement of anti-counterfeiting technology, it is difficult for us to identify the true and false from the appearance.
