Nine ways to distinguish the authenticity of lithium battery manufacturers

  • by

At present, mobile phones are an indispensable tool for people, and the replacement is very fast. The service life of mobile phone batteries is limited, so sometimes the mobile phone is still in good condition, but the battery is very useless. At this time, it becomes necessary to buy a new mobile phone battery. As a mobile phone user, how should you choose the counterfeit and shoddy batteries that are flooding the market? Below, the author will teach you a few tricks, hoping to help you improve your understanding of mobile phone batteries.

  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; while the capacity of lithium-ion mobile phone batteries is generally between 1300-1400mAh, so the energy storage lithium battery manufacturers use time after being fully charged is about hydrogen It is 1.5 times that of nickel batteries and about 3.0 times that of nickel-cadmium batteries. If you find that the working time of the lithium-ion mobile phone battery you purchased is not as long as advertised or specified in the manual, it may be counterfeit.odm 150ah lifepo4
  2. Look at the plastic surface and plastic material. The anti-wear surface of the genuine battery is uniform, and it is made of PC material, which is not brittle;
  3. All genuine mobile phone batteries should be neat in appearance, without unnecessary burrs, with a certain roughness on the outer surface and a comfortable feel; the inner surface should feel smooth, and fine longitudinal scratches can be seen under the light. The battery electrodes have the same width as the cell phone battery, and the corresponding positions below the battery electrodes are marked with [+] and [-] marks.
  4. For the original battery, its surface color and texture are clear, uniform, clean, without obvious scratches and damage; the battery mark should be printed with the battery model, type, rated capacity, standard voltage, positive and negative signs, manufacturer's name . The hand feel should be smooth and non-blocking, the tightness is appropriate, the fit with the hand is good, and the lock is reliable; the hardware piece has no obvious scratches, blackening and greening. If the mobile phone battery we purchased does not conform to the above phenomenon, it can be preliminarily concluded that it is a fake.
  5. At present, many mobile phone manufacturers are also starting from their own perspectives, by striving to improve the level of craftsmanship, to improve the difficulty of counterfeiting mobile phones and their accessories, thereby further curbing the phenomenon of counterfeit and parallel imports. Generally, regular mobile phone products and their accessories must be consistent in appearance. Therefore, if we install the purchased mobile phone battery, we should carefully check the color of the body and the battery bottom case. If the color and light are the same, it is the original battery. Otherwise, the battery itself is dull and dull, and it may be a fake battery.odm 150ah lifepo4
  6. Observe the abnormal situation of charging. Generally, there should be an overcurrent protector inside the genuine mobile phone battery. In the case of excessive current caused by external short circuit, etc., the circuit will be automatically cut off to avoid burning or damaging the mobile phone; the lithium-ion battery also has an overcurrent protection circuit. Standardize electrical appliances. When the AC current is too large, it will automatically cut off the power supply, resulting in failure to charge. In the normal condition of the battery, it can automatically return to the conduction state. If, during the charging process, we find that the battery is seriously hot or smoking, or even explodes, it means that the battery must be fake.
  7. Look carefully at the anti-counterfeiting signs. For example, the word NOKIA hidden obliquely under the sticker is the trick. Clear and flawless is the original product; dull and tarnished is a counterfeit product.

If you look closely, you may also find the name of the manufacturer. For example, for Motorola batteries, its anti-counterfeiting trademark is diamond-shaped, and no matter from any angle, it can flash with a three-dimensional effect, and Motorola, Original and clear printing are genuine. On the contrary, once the color is dim, the three-dimensional sense is insufficient, and the words are blurred, it may be a fake.

  1. Measure the charging voltage of the battery block. If a lithium-ion mobile phone battery block is faked with a nickel-cadmium or nickel-hydrogen battery block, it must be composed 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.
  2. With the help of special tools. In the face of more and more types of mobile phone batteries on the market, and the counterfeiting technology is becoming more and more sophisticated, some large companies are also constantly improving anti-counterfeiting technology, such as the new Nokia mobile phone battery, which has a special marking on the logo. Processing, requires a special prism to identify, and this prism is only available in Nokia. Therefore, with the improvement of anti-counterfeiting technology, it is difficult for us to identify the true and false from the appearance.
