Teach you to distinguish the true and false of lithium battery manufacturers
At present, the mobile phone is an indispensable tool for people, and the replacement is very fast. The battery life of a mobile phone is limited, so sometimes the mobile phone is fine, but the battery is very useless. At this time, buying a new mobile phone battery becomes a must. As a mobile phone user, how to choose counterfeit and inferior batteries that are flooding the market? Below, I will teach you a few tricks, hoping to help you improve your understanding of mobile phone batteries.
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 lithium-ion mobile phone batteries is generally between 1300-1400mAh, so the time for energy storage lithium battery manufacturers to use after fully charged is about hydrogen 1.5 times that of nickel batteries and about 3.0 times that of cadmium nickel batteries. If you find that the working hours of the lithium-ion cell phone battery block you bought 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 is made of recycled materials, which is easy to 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 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. For 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 non-blocking, with suitable elasticity, good fit with the hand, and reliable locking; the hardware should be free of obvious scratches, black and green. 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 from their own point of view, through their 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 we bought, we should carefully compare the color of the body and the bottom of the battery. If the color is the same, 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; lithium-ion batteries also have 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 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 the trick. 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 from any angle, and 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.
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 cell 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 block When the total charging voltage 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 technology, such as the new Nokia mobile phone battery, it has a special logo 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.
