Compare the battery capacity. The average cadmium nickel battery is 500mAh or 600mAh, and the hydrogen hydrogen battery is only 800-900mAh; the capacity of lithium ion mobile phone batteries is generally between 1300-1400mAh, so the time after sufficient lithium battery is about the time. 1.5 times, about 3.0 times the cadmium nickel battery. If you find that the working hours of lithium -ion mobile phone battery blocks you buy are not promoted or stipulated in the instructions, it may be counterfeit.

Look at the plastic surface and plastic material. The genuine battery has a uniform polishing surface, which is made of PC, without crispy cracks; counterfeit batteries have no anti -grinding surface or too rough, using regenerative materials, easy to crack.

Measure the charging voltage of the battery block. If the cadmium nickel and nickel hydrogen battery blocks are used for counterfeit lithium -ion mobile phone battery blocks, it must be composed of 5 monomer batteries. 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 cadmium nickel and nickel hydrogen hydrogen battery.

For the original battery, its battery surface has a clear texture, uniform, clean, and no obvious scratches and injuries; the battery mark should be printed with battery models, types, rated capacity, standard voltage, positive and negative electrode signs, and manufacturing plants. The feel should be smooth and unobstructed. It is appropriate to relax, and it is well matched with the hands. The lock is reliable; the hardware tablets have no obvious scratches and black and green. If the mobile phone battery we buy does not match the above phenomenon, it can be preliminarily determined that it is a fake.

Many mobile phone manufacturers also start from their own perspectives and improve the level of fraud in mobile phones and accessories by striving to improve the level of technology, thereby further curbing the phenomenon of the flood of fake parallel imports. Generally, regular mobile phone products and its accessories must be consistent on the outside. Therefore, if we install the mobile phone battery bought back, we should carefully compare the fuselage and the battery bottom. If the color is dark, it is the original battery. Otherwise, the battery itself is dull and lustrous, and it may be a fake battery.

Observe the abnormal situation of charging. Generally, there should be an overcurrent protector inside the genuine mobile phone battery. When the external short circuit is caused by the large current, the circuit is automatically cut off to avoid burning or damaging the mobile phone; the lithium -ion battery has another overcurrent protection line. When the electric current is too large, the power will also be automatically cut off, which will cause failure to enter. In normal batteries, it can automatically restore to the direction state. If we find that the battery is severely fever or smoke or even explode during the charging process, indicating that the battery must be fake.

With the help of special tools. In the face of more and more types of mobile phone batteries on the market, and counterfeiting technology is also getting clever, some large companies are constantly improving anti -counterfeiting technology. With the improvement of anti -counterfeiting technology, it is difficult for us to identify authenticity from the appearance.
