Thirteen ways to identify true and false lithium-ion batteries

There are 13 ways to correctly identify the real lithium-ion battery. There is a mixed market, and our consumers must be refined into the eyes of fire to prevent harm. The same is true for lithium-ion batteries. Today, lithium-ion battery manufacturers will lead you to understand how to distinguish between real and fake lithium-ion batteries. The following are 13 types: 1. Use special detectors and use special tools 3. Compare the size of battery capacity 4. Original batteries, with clear, uniform and clean surface color and texture, without obvious scratches and damage; the battery logo should be Indicate the battery model, model, rated capacity, standard voltage, positive and negative signs and manufacturer's name. The hand feels smooth and has no blockage, suitable for air tightness, good hand feel, and reliable locking; no obvious scratches, blackening, or greening. If the mobile phone battery we bought is inconsistent with the above phenomenon, we can preliminarily conclude that it is fake. 5. Observe abnormal charging conditions. Under normal circumstances, there should be an over-current protector inside the battery of a genuine mobile phone. In the case of an external short circuit, the circuit will be automatically cut off to avoid burning or damaging the phone; lithium-ion batteries also have an over-current protection line. When using non-standard electrical appliances, If the current is too high, it will automatically cut off the power supply, causing the charging to fail. Under normal conditions, the battery can automatically return to the on state. If we find that the battery overheats, smokes or even explodes during the charging process, it must be fake. Measure the charging voltage of the battery block. If a cadmium-nickel and nickel-hydrogen battery block is used to counterfeit a lithium-ion cell phone battery block, it must consist of 5 single 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 a cadmium-nickel and nickel-hydrogen battery block. 7. All genuine mobile phone batteries have a neat appearance, no excessive burrs, a certain degree of roughness on the outer surface, and a comfortable feel; the inner surface feels smooth, and slight longitudinal scratches can be seen under the light. The battery electrodes have the same width as the mobile phone battery, and the corresponding positions under the battery electrodes are marked with [+] and [-]. The isolation material of the battery charging electrode is the same as the shell material, but not the same. Look at the plastic surfaces and materials. The genuine battery has a uniform anti-wear surface and uses PC material without brittle cracks; the fake battery has no anti-wear or too rough surface, and uses recycled materials, which is easy to be brittle and crack. When we distinguish between real batteries, we often overlook a small detail, which is the tactile feel of the battery. Because of the real mobile phone batteries of various famous brands, most of their contacts are annealed and should be matte instead of bright. Therefore, the authenticity of the mobile phone battery can be preliminarily judged based on this. In addition to carefully observing the color of the touch, fake mobile phone batteries are often made of copper, so its color is red or white, while real mobile phone batteries should be this pure golden yellow, red or white may be fake. 10. The exterior of lithium-ion batteries is generally marked in English as 7.2-type lithium-ion batteries (lithium-ion batteries) or 7.2-type lithium-ion secondary batteries (lithium-ion secondary batteries), and 7.2-type lithium-ion rechargeable batteries (lithium-ion rechargeable batteries). Therefore, when buying a mobile phone battery, you must look at the signs on the appearance of the battery block to prevent the battery type from being unclear and the cadmium nickel and nickel hydroxide batteries are mistaken for lithium ion batteries. At present, many mobile phone manufacturers are also from their own point of view, through their efforts to improve the technical level, to increase the difficulty of mobile phones and accessories counterfeiting, so as to further curb the phenomenon of counterfeit gray goods. General mobile phone products and accessories must have the same appearance under general requirements. So if we bought the battery on the mobile phone, should we carefully check the body and the battery shell? The color, if the color is the same light and dark, it is the original battery. Otherwise, the battery itself is dim and may be a fake battery. 12. Look carefully at the safety signs. For example, the word NOKIA hidden under the sticker is the trick. Clear and flawless is an original product; Fading is a counterfeit product. If we buy a fake lithium-ion battery, we may cause irreparable damage, so it is very important to identify the real lithium-ion battery!
