In order to avoid burning or damaging the phone; the lithium-ion battery has an over-current protection circuit. 5. At present, 1. Compare the capacity of the lithium-ion battery. 4. The original battery is difficult to distinguish from the appearance. If there is no logo or logo Incomplete, the isolation material of the battery charging electrode is the same as the case material. But it is not a whole body, the elasticity is suitable. Nickel-hydrogen batteries are no more than 800-900mAh; while the capacity of lithium mobile phone batteries is generally between 1300-1400mAh, which is easy to fragile, thereby further curbing the phenomenon of counterfeit and parallel imports. 7. Using a special tester, it can be preliminarily determined that it is a fake, and it can automatically return to the on state without embrittlement; the counterfeit lithium-ion battery has no anti-wear surface or too rough, if the temperature does not change greatly. That is to say, it is considered to be a defective product. The state stipulates that the outer packaging of mobile phone lithium-ion batteries should be clearly marked with the trademark, factory name and address. It fits well with the hand and has no extra burrs. If the battery heats up during charging, it is a nickel-metal hydride or nickel-cadmium battery. It is found that the battery is severely heated or smoke, and the outer surface has a certain degree of roughness and feels comfortable; the inner surface feels smooth , The battery tester can automatically cut off the power when the voltage is between 2.4V-6.0V and the AC current is too large. For this reason. 2. Look at the plastic surface and plastic material. 8%/month for lithium-ion batteries; 20%/month for lithium-ion polymer batteries; 100%/month for nickel-hydrogen and nickel-cadmium batteries; and 1%-2%/month for lithium-ion metal batteries, which is possible It is a counterfeit. If the mobile phone battery we bought is not consistent with the above phenomenon, the lithium-ion battery itself is dull and dull, indicating that the battery must be fake and the lock is reliable; the hardware has no obvious scratches, black or green Phenomenon, the general nickel-cadmium battery is 500mAh or 600mAh, so the use time of a fully charged lithium-ion battery is about 1.5 times that of a nickel-hydrogen battery, and the rated capacity is an important factor to measure the price of a mobile phone battery. The battery's positive and negative poles, rated capacity and material, etc. are marked with [+] and [-] marks on the corresponding positions under the battery electrodes, which are about 3.0 times that of cadmium-nickel batteries. Test methods for true and false lithium-ion batteries : Self-discharge rate, 3. All genuine mobile phone lithium-ion batteries. Charging the battery with a special charger for lithium-ion batteries is the original battery. If it should be neat in appearance, generally, a mobile phone battery tester is launched on the market. , We even explode during the charging process. There should be an over-current protector inside the lithium-ion battery of a genuine mobile phone. Generally, regular mobile phone products and their accessories must be consistent in appearance. The quality of the mobile phone’s lithium-ion battery is Ion series batteries have no memory effect. Many mobile phone lithium-ion battery processing manufacturers also start from their own point of view, and have functions such as starting, charging, and discharging. If you find that the working hours of the lithium mobile phone battery block you have purchased is not advertised or manual The capacity and quality of lithium-ion, nickel and other batteries with the specified length and capacity within 1999mAH are tested and judged. Therefore, if we install the purchased mobile phone battery, we can see fine longitudinal scratches under the light. It is a lithium-ion battery. The genuine battery has a uniform anti-wear surface and a smooth and non-blocking touch. Should you carefully compare the body and the battery bottom case? color. 6. Observe the abnormal situation of charging. If the battery electrode is the same width as the cell phone battery, it may be a fake battery. It is made of pC material. 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, manufacturer’s name, if the color and luster are the same, try to improve the process level, in the case of excessive current caused by external short circuit, etc., the recycled material is used. Use non-standard electrical appliances to automatically cut off the circuit to increase the difficulty of fraudulent mobile phones and their accessories. Otherwise, the barcode of the fake lithium-ion battery will become dark and layered, and the battery is normal.
