The service life of mobile phone batteries is limited, so sometimes the mobile phone is still good, but the battery is very worn out. At this time, it becomes necessary to buy a new mobile phone battery. As a mobile phone user, how to choose in the face of the flood of counterfeit and shoddy batteries in the market?

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; while the capacity of lithium-ion mobile phone batteries is generally between 1300-1400mAh, so after the lithium-ion battery is fully charged

The use time is about 1.5 times that of nickel-hydrogen batteries and about 3.0 times that of nickel-cadmium batteries. If it is found that the working time of the lithium-ion mobile phone battery block you purchased is not as long as advertised or specified in the manual, it may be counterfeit.

2. Look at the plastic surface and plastic material. The anti-wear surface of the genuine battery is uniform, and it is made of PC material, without brittleness; the counterfeit battery has no anti-wear surface or is too rough, and is made of recycled materials, which is easy to be brittle.

3. All genuine mobile phone batteries should be neat in appearance, without extra 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 width of the battery electrode is the same as that of the battery sheet of the mobile phone. The corresponding positions below the battery electrode are marked with [+] and [-]. The isolation material of the battery charging electrode is the same as that of the shell, but not integrated.

4. For the original battery, its surface color texture 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 . get on the phone

The hand feel should be smooth and non-blocking, suitable for tightness, good fit with the hand, and reliable lock; the metal sheet has no obvious scratches, blackening, or greening. If the mobile phone battery we purchased does not match the above phenomenon, it can be preliminarily determined to be a fake.

5. At present, many mobile phone manufacturers are also starting from their own point of view, making efforts to improve the technical level to increase the difficulty of counterfeiting mobile phones and their accessories, so as to further curb the phenomenon of counterfeit parallel imports. General formal mobile phone products and their accessories require consistency in appearance. Therefore, if we install the mobile phone battery we bought back, we should carefully compare the color of the fuselage and the battery bottom case. 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, which will automatically cut off the circuit when the current is too large due to an external short circuit, so as not to burn or damage the mobile phone; the lithium-ion battery also has an over-current protection circuit. Standard electrical appliances, when the AC current is too large, it will automatically cut off the power supply, resulting in failure to charge. When the battery is normal, it can automatically return to the conduction state. If, during the charging process, we find that the battery is seriously heated or smokes, 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. Flawless is the original; dull is the fake. If you look closely, you may also find the name of the maker. For example, for Motorola batteries, its anti-counterfeit trademark is diamond-shaped, and it can flash and have a three-dimensional effect no matter from any angle. If Motorola, Original and printing are clear, it is genuine. On the contrary, once the color is dull, the three-dimensional effect 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 five 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 total charging voltage of the battery 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 technology, such as the new Nokia mobile phone battery, it is on the logo

It has been specially processed and needs to be identified with a special prism, which is only available from Nokia. Therefore, with the improvement of anti-counterfeiting technology, it is difficult for us to identify the true and false from the appearance.

The service life of mobile phone batteries is limited, so sometimes the mobile phone is still good, but the battery is very worn out. At this time, it becomes necessary to buy a new mobile phone battery. As a mobile phone user, how to choose in the face of the flood of counterfeit and shoddy batteries in the market? Below, the author will teach you a few tricks, hoping to help you improve your understanding of mobile phone batteries in “ID card query” and “mobile phone location”.

It has been specially processed and needs to be identified with a special prism, which is only available from Nokia. Therefore, with the improvement of anti-counterfeiting technology, it is difficult for us to identify the true and false from the appearance.

10. Utilize dedicated detectors. The quality of mobile phone batteries is difficult to distinguish from the appearance alone. For this reason, a mobile phone battery tester has been introduced on the market, which can test the capacity and quality of various batteries such as lithium and nickel with a voltage between 2.4V-6.0V and a capacity within 1999mAH. Discrimination, and has the functions of starting, charging, discharging and so on. The whole process is controlled by the microprocessor according to the characteristics of the battery, which can realize the digital display of technical parameters such as the measured voltage, current and capacity.

11. Lithium-ion mobile phone batteries are generally marked in English with 7.2Vlithiumionbattery (lithium-ion battery) or 7.2Vlithiumsecondarybattery (lithium secondary battery), 7.2Vlithiumionrechargeablebattery lithium-ion rechargeable battery). Therefore, when buying mobile phone batteries, you must see the signs on the appearance of the battery block to prevent the nickel-cadmium and nickel-hydrogen batteries from being mistaken for lithium-ion mobile phone batteries because you do not see the battery type clearly.

12. When people identify genuine and fake batteries, they often overlook a small detail, that is, the contacts of the battery. Because the contacts of various brand-name real mobile phone batteries are mostly annealed and should be matte, not shiny, so based on this point, the authenticity of the mobile phone battery can be preliminarily judged. In addition, carefully observe the color of the contacts. The contacts of fake mobile phone batteries are often made of copper, so its color is red or white, while the real mobile phone battery should be this pure golden yellow, reddish color. Or it may be fake.
