"Lithium battery" is a battery with lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte. Below, I will share the identification method of lithium battery for you, hoping to help you!
Compare battery capacity.
The average nickel-cadmium battery is 500mAh or 600mAh, and the nickel-hydrogen battery is only 800-900mAh. The capacity of lithium-ion mobile phone batteries is generally between 1300- 1400mAh, so the service life of lithium batteries is about 1.5 times that of nickel-hydrogen batteries and about 3.0 times that of nickel-cadmium batteries. If it is found that the working time of the lithium-ion mobile phone battery block you bought is not as long as that stipulated in the advertisement or manual, it may be counterfeit.
Look at the plastic surface and plastic material.
The wear-resistant surface of genuine battery is uniform, made of PC material, and there is no brittle crack phenomenon; Counterfeit batteries have no wear-resistant surface or are too rough, and are made of recycled materials, which are easy to crack.
Measuring the charging voltage of the battery block
If Ni-Cd or Ni-MH battery blocks are used as counterfeit lithium-ion mobile phone battery blocks, they must be composed of five single batteries. Generally, the charging voltage of a single battery does not exceed 1.55V, and the total battery block voltage does not exceed 7.75V When the total battery block charging voltage is lower than 8.0V, it may be a nickel-cadmium or nickel-hydrogen battery.
For the original battery, the surface color and texture of the battery are clear, uniform and clean, without obvious scratches and damage; The battery identification shall be printed with the model, type, rated capacity, standard voltage, sign and manufacturer's name of the battery.
The handle should be smooth and smooth, the tightness should be appropriate, the hands should be well matched and the lock should be reliable; Metal parts have no obvious scratches, blackening and turning green. If the mobile phone battery we bought does not conform to the above phenomenon, we can preliminarily conclude that it is a fake.
Many mobile phone manufacturers also strive to improve their technology level from their own perspective, so as to improve the counterfeiting difficulty of mobile phones and their accessories, thus further curbing the phenomenon of counterfeit goods.
Generally, regular mobile phone products and their accessories require the same appearance. So when we install the bought mobile phone battery, we should carefully compare the fuselage and the battery bottom case? The color, if the color is the same, is the original battery. Otherwise, the battery itself is dim and may be a fake battery.
Observe the abnormal situation of charging
Generally, there should be an over-current protector inside the genuine mobile phone battery, which will automatically cut off the circuit in case of excessive current caused by external short circuit to avoid burning or damaging the mobile phone; Lithium-ion batteries also have overcurrent protection circuits. When using non-standard electrical appliances, the power supply will be automatically cut off if the alternating current is too large, resulting in charging failure. Under normal circumstances, the battery can automatically return to the on state. If, in the process of charging, we find that the battery is seriously hot, smoking or even exploding, it means that the battery must be fake.
If you look carefully, you may also find the name of the manufacturer.
For example, Motorola battery, whose' anti-counterfeiting trademark is diamond, can flash a three-dimensional effect from any angle, while Motorola, original and clearly printed, is genuine. On the contrary, once the color is dim, the three-dimensional sense is insufficient, and the text is blurred, it may be a fake.
With the help of special tools
Faced with more and more kinds of mobile phone batteries in the market, as well as more and more sophisticated counterfeiting technology, some large companies are constantly improving their anti-counterfeiting technology. For example, the new Nokia mobile phone batteries have been specially treated on the logo, which requires special prisms to identify them. Only Nokia has them. Therefore, with the improvement of anti-counterfeiting technology, it is difficult for us to identify the authenticity from the appearance.
