How to choose fake and inferior 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 the lithium-ion mobile phone battery is generally between 1300-1400mAh, so the time required for the lithium-ion battery to be satisfied is about the nickel-hydrogen battery. 1.5 times that of nickel-cadmium batteries, about 3.0 times that of nickel-cadmium batteries. Assuming that the working hours of the lithium-ion mobile phone battery block you have purchased are not advertised or as long as specified in the manual, it may be a fake charge. 2. Look at the plastic surface and plastic materials. The wear-resistant surface of the genuine battery is uniform, and the PC material is selected, and there is no brittleness; the fake rechargeable battery has no wear-resistant surface or is too rough, and the recycled material is selected, which is easy to brittle. 3. All genuine mobile phone batteries should be regular in appearance, without excessive burrs, and have certain roughness on the 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 [-] symbols. The barrier 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 significant scratches and hazards; the battery logo should be printed with battery type, type, additional capacity, standard voltage, positive and negative signs, and manufacturer name. The hand feel should be lubricated without clogging, suitable for tightness, excellent cooperation with the hand, and reliable locking; the hardware should be free of significant scratches, blackening and greening. Assuming that the mobile phone battery we bought does not conform to the above phenomenon, we can begin to conclude that it is a fake. 5. Now, many mobile phone manufacturers are also setting sail from their own point of view, and through their efforts to advance the level of technology, to advance the difficulty of counterfeiting mobile phones and their accessories, and then to further curb the phenomenon of many counterfeit goods. Generally, regular mobile phone products and their accessories require compatibility on the surface. Therefore, we assume that when installing the purchased mobile phone battery, we should carefully compare the color of the body and the battery bottom case. If the color is dark and light, it is the original battery. Otherwise, the battery itself is dull and dull, and it may be a fake battery. 6. Query the abnormal situation of charging. Generally, there should be an over-current maintainer 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 blocked to prevent burning or damage to the mobile phone; lithium-ion batteries also have an over-current maintenance circuit. For standard electrical appliances, when the AC current is too large, the power supply will be automatically blocked, causing failure to charge. When the battery is normal, it can automatically return to the on state. Assuming that during the charging process, we find that the battery is severely heated, or smokes, or even bursts, indicating 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. Clearly Flawless is the original product; Dim Incapacity is a counterfeit product. If you look closely, you might find the name of the maker. For example, for Motorola batteries, its anti-counterfeiting trademark is diamond-shaped, and it can flash and have a three-dimensional effect from any point of view, and Motorola, Original and printed clearly, are genuine. On the contrary, once the color is dim, the three-dimensional sense is short, and the words are blurred, it may be a fake. 8. Measure the charging voltage of the battery block. Assuming that nickel-cadmium and nickel-hydrogen battery blocks are used to fake lithium-ion mobile phone battery blocks, it is necessary to consist 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 total charging voltage of the battery block is lower than 8.0V, it may be a nickel-cadmium or nickel-hydrogen battery. 9. With special tools. Faced with more and more types of mobile phone batteries on the market, and the technology of fake charging is becoming more and more sophisticated, some large companies are also constantly advancing anti-counterfeiting technology, such as the new Nokia’s mobile phone battery, which has carried out special measures in front of the logo. For processing, a special prism is used to identify it, and this prism only needs to be provided by Nokia. Therefore, with the advancement of anti-counterfeiting technology, it is difficult for us to distinguish serious and fake from the appearance. 10. Use a dedicated detector. The quality of mobile phone batteries is difficult to distinguish from the appearance. To this end, a mobile phone battery tester has been introduced on the market. The battery tester can detect the capacity and quality of various batteries such as lithium and nickel with a voltage between 2.4V and 6.0V and a capacity within 1999mAH. And has the functions of initiating, charging, and discharging. The whole process is controlled by the microprocessor according to the battery characteristics, and the digital display of the measured voltage, current, capacity and other technical parameters can be completed. 11. Lithium-ion mobile phone batteries are generally marked with English 7.2Vlithiumionbattery (lithium ion battery) or 7.2Vlithiumsecondarybattery (lithium secondary battery), 7.2Vlithiumionrechargeablebattery (lithium ion rechargeable battery). Therefore, when buying a mobile phone battery, you must see the signs on the surface of the battery block to prevent the nickel-cadmium and nickel-hydrogen batteries from being mistaken for lithium-ion mobile phone batteries because the battery type is not clearly seen. 12. When we distinguish between true and false batteries, we often overlook a small detail, that is, the battery contacts. Since all kinds of brand-name real cell phone batteries, their contacts are mostly annealed and should be matte, not shiny, so you can start to determine the authenticity of the cell phone battery based on this. In addition, we must carefully check 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 simple golden yellow. Red or white may be fake.
