How to correctly identify the capacity of the 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; and the capacity of the lithium-ion mobile phone battery is generally between 1300-1400mAh, so the use time of the lithium battery is about that of the nickel-hydrogen battery. 1.5 times, which is about 3.0 times that of nickel-cadmium batteries. If it is found that the working hours of the lithium-ion mobile 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. 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 it is not integrated. 4. Regarding the original battery, its surface color and 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 . 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 bought does not conform to the above phenomenon, it can be preliminarily determined to be a fake. 5. At present, many mobile phone manufacturers are also from their own point of view, through 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. So if we install the mobile phone battery that we bought back, we should carefully compare the body with the battery bottom shell? 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; the lithium battery also has an over-current protection circuit, which is not standardized when used. Electrical appliances, when the AC current is too large, will automatically cut off the power, causing the charging to fail, and the battery can automatically return to the on state when the battery is normal. If, during the charging process, we find that the battery is severely heated or smoked, or even exploded, it means that the battery must be fake.
