Lithium Battery Identification Battery

Compare the size of battery capacity. The general cadmium nickel battery is 500mAh or 600mAh, and the hydrogen nickel battery is only 800-900mAh; The capacity of lithium-ion mobile phone batteries is generally between 1300-1400mAh, so the usage time of a fully charged lithium-ion battery is about 1.5 times that of a nickel hydrogen battery and about 3.0 times that of a nickel cadmium battery. If you find that the working hours of the lithium-ion phone battery pack you purchased are not advertised or specified in the manual, it may be counterfeit.
Look at the plastic surface and material. The anti wear surface of the genuine battery is uniform and made of PC material, without any brittle cracking phenomenon; Counterfeit batteries have no anti wear surface or are too rough, using recycled materials that are prone to cracking.
Measure the charging voltage of the battery block. If cadmium nickel or hydrogen nickel battery blocks are used to counterfeit lithium-ion mobile phone battery blocks, they must be composed of five individual 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 below 8.0V, it may be a cadmium nickel or hydrogen nickel battery.
For original batteries, the surface color and texture of the battery are clear, uniform, clean, and free from obvious scratches and damage; The battery logo should be printed with the battery model, type, rated capacity, standard voltage, positive and negative pole markings, and the manufacturer's name. The hand feel should be smooth and unobstructed, with appropriate tightness, good coordination with the hand, and reliable locking buckle; There are no obvious scratches, blackening, or greening on the hardware. If the mobile phone battery we purchased does not match the above phenomenon, we can preliminarily conclude that it is fake.
Many mobile phone manufacturers also take their own perspective and strive to improve the level of craftsmanship to increase the difficulty of counterfeiting mobile phones and their accessories, thereby further curbing the phenomenon of counterfeit and counterfeit goods flooding. Generally, legitimate mobile phone products and their accessories require consistency in appearance. Therefore, when installing the purchased mobile phone battery, we should carefully compare the body and battery bottom case. If the color is consistent, it is the original battery. Otherwise, if the battery itself is dull and dull, it may be a fake battery.
Observe the abnormal charging situation. Generally, genuine mobile phone batteries should have an overcurrent protector inside, which automatically cuts off the circuit in case of external short circuits or excessive current to avoid burning or damaging the phone; Lithium ion batteries also have overcurrent protection circuits. When non-standard electrical appliances are used and the AC current is too high, the power supply will be automatically cut off, resulting in inability to charge. Under normal circumstances, the battery can automatically return to a conductive state. If, during the charging process, we find that the battery is severely heating, smoking, or even exploding, it indicates that the battery is definitely fake.
With the help of specialized tools. Faced with the increasing variety of mobile phone batteries in the market and the increasingly sophisticated technology of counterfeiting, some large companies are also continuously improving their anti-counterfeiting technology. With the improvement of anti-counterfeiting technology, it becomes difficult for us to identify authenticity from the appearance.
