How to judge whether the lithium battery is original?

1. Compare the size of the battery capacity. The general nickel-cadmium battery is 500mAh or 600mAh, and the nickel-hydrogen battery is only 800-900mAh; and the capacity of the lithium-ion mobile phone battery is generally between 1300-1400mAh, so the use time of the lithium battery after fully charged is about the time of the nickel-hydrogen battery 1.5 times, which is about 3.0 times that of cadmium nickel batteries. If it is found that the working hours of the lithium-ion mobile phone battery block you have purchased is not advertised or specified in the manual, it may be counterfeit. 2. Look at the plastic surface and plastic material. The wear-resistant surface of the genuine battery is uniform, and it is made of PC material, without brittleness; the counterfeit battery has no wear-resistant surface or is too rough, and it is made of recycled materials, which is easy to be brittle. 3. All genuine mobile phone batteries should be neat in appearance, without excessive burrs, and have a certain roughness on the outer surface and feel comfortable to the touch; the inner surface is smooth to the touch, and fine longitudinal scratches can be seen under the light. The battery electrode has the same width as the cell phone battery, and the corresponding position under the battery electrode is marked with [+] and [-] marks. The isolation material of the battery charging electrode is the same as the shell material, but it is not integrated. 4. Regarding the original battery, the color and texture of the battery surface is clear, uniform, clean, without obvious scratches and damage; the battery logo should be printed with the battery model, type, rated capacity, standard voltage, positive and negative signs, and the name of the manufacturer . The hand feel should be smooth and unobstructed, with suitable tightness, good fit with the hand, and reliable lock; the hardware should have no obvious scratches, blackening or greening. If the mobile phone battery we purchased does not conform to the above phenomenon, it can be preliminarily determined to be a fake. 5. At present, many mobile phone manufacturers are also from their own point of view, through efforts to improve the level of technology to increase the difficulty of counterfeiting mobile phones and their accessories, so as to further curb the phenomenon of counterfeit parallel imports. Generally, regular mobile phone products and their accessories must be consistent in appearance. So if we install the battery of the mobile phone we bought, we should carefully compare the body and the battery bottom case? Color, if the color is the same light and dark, it is the original battery. Otherwise, the battery itself is dull and dull, and it may be a fake battery. 6. Observe the abnormal situation of 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, it will automatically cut off the circuit to avoid burning or damaging the mobile phone. The lithium battery also has an over-current protection circuit, which can be used if it is not standardized. Electrical appliances, when the AC current is too large, will automatically cut off the power, 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 generates severe heat or smoke, or even explodes, it means that the battery must be fake. 7. 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 batteries, its anti-counterfeiting label 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 a fake. 8. Measure the charging voltage of the battery block. If a nickel-cadmium or nickel-hydrogen battery block is used to counterfeit a lithium-ion mobile phone battery block, it must be composed of 5 single cells. The charging voltage of a single battery generally does not exceed 1.55V, and the total voltage of the battery block does not exceed 7.75V. When the battery When the total charging voltage of the block is lower than 8.0V, it may be a nickel-cadmium or nickel-hydrogen battery. 9. 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. To deal with it, a special prism is used to identify it, 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.
