How to distinguish the authenticity of the mobile phone battery?

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 is about that of the nickel-hydrogen battery. 1.5 times, which is about 3.0 times of cadmium nickel storage battery. 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 a 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 degree of 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 is the same width as the cell phone battery sheet, 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 not integrated. 4. Regarding the original battery, its surface color and texture are 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 bought 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. Therefore, if we install the battery of the mobile phone that we bought, we should carefully compare the body and the bottom of the battery? 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, the circuit will be automatically cut off to avoid burning or damaging the mobile phone. The lithium-ion battery also has an over-current protection circuit. Standardize electrical appliances. When the AC current is too large, the power supply will be automatically cut off, resulting in failure 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 heating or smoking, or even explode, 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, regarding Motorola battery, its anti-counterfeiting trademark is diamond-shaped, and it can flash and have a three-dimensional effect from any angle, and Motorola, Original and printed clearly, are genuine. On the contrary, once the color is dim, the three-dimensional impression is insufficient, and the words are blurred, it may be a fake.
