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 mobile phone battery is generally between 1300-1400mAh, so the use time of the lithium-ion battery is about the time of the nickel-hydrogen battery. 1.5 times, which is about 3.0 times that of cadmium-nickel batteries. If it is found that the working hours of the lithium cell 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. Measure the charging voltage of the battery block. If a nickel-cadmium or nickel-hydrogen battery block is used to counterfeit a lithium mobile phone battery block, it must be made up 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. 4. Regarding 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 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 purchased does not conform to the above phenomenon, it can be preliminarily determined to be a fake. 5. Many mobile phone manufacturers also start from their own point of view and make efforts to improve the level of craftsmanship to increase the difficulty of counterfeiting mobile phones and their accessories, so as to further curb the flood of counterfeit goods. Generally, regular mobile phone products and their accessories must be consistent in appearance. So if we install the battery of the mobile phone we bought, we should carefully compare the body and the battery bottom case? 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. Lithium-ion batteries also have an over-current protection circuit. When using non-standard electrical appliances , When the AC current is too large, it will automatically cut off the power supply, causing the battery to fail 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.
