Lithium Battery Identification Battery

Compare battery capacities. General nickel cadmium batteries are 500mAh or 600mAh, while nickel hydrogen batteries are only 800-900mAh; The capacity of lithium-ion mobile phone batteries is generally between 1300-1400mAh, so the usage time of lithium batteries after full charge is about 1.5 times that of nickel hydrogen batteries, and about 3.0 times that of nickel cadmium batteries. If you find that the working hours of the lithium-ion mobile phone battery you purchased are not advertised or specified in the manual, it may be counterfeit.
Look at the plastic surface and material. Genuine batteries have uniform wear resistant surfaces, made of PC material, without brittle cracking; The counterfeit battery has no wear resistant surface or is too rough, and is made of recycled material, which is prone to cracking.
Measure the charging voltage of the battery block. If a nickel cadmium or nickel hydrogen battery is used to counterfeit a lithium ion mobile phone battery, it must be composed of five individual batteries, with a charging voltage of no more than 1.55V for a single battery and a total voltage of no more than 7.75V for the battery. When the total charging voltage of the battery block is lower than 8.0 V, it may be a nickel cadmium or nickel hydrogen battery.
For original batteries, the surface color and texture of the battery are clear, uniform, clean, and free of obvious scratches and damage; The battery logo shall be printed with the battery model, type, rated capacity, standard voltage, positive and negative electrode logo, and manufacturer's name. The handle should be smooth and unblocked, with appropriate tightness, good coordination with the hand, and reliable locking; The hardware piece shall be free of obvious scratches, blackening, and greening. If the mobile phone battery we purchased does not match the above phenomenon, we can preliminarily conclude that it is a fake.
Many mobile phone manufacturers have also made efforts to improve the technological level from their own perspective to improve the difficulty of counterfeiting mobile phones and their accessories, thereby further curbing the proliferation of counterfeit and pirated goods. Generally, formal mobile phone products and their accessories must be consistent in appearance. Therefore, when installing a purchased mobile phone battery, we should carefully compare the body and battery bottom. If the color and shade are consistent, it is the original battery. Otherwise, the battery itself is relatively dull and matt, which may be a fake battery.
Observe the abnormal charging condition. Generally, the battery of a genuine mobile phone should have an overcurrent protector inside it, which automatically cuts off the circuit in case of excessive current caused by external short circuits, to avoid burning or damaging the phone; The lithium ion battery also has an overcurrent protection circuit. When using non-standard electrical appliances, the power supply will also be automatically cut off when the AC current is too large, resulting in a lack of charging. Under normal conditions, the battery can automatically return to a conductive state. If, during the charging process, we find that the battery is seriously heating or smoking, or even exploding, it indicates that the battery must be fake.
With the aid of special tools. Faced with the increasing variety of mobile phone batteries on 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 is difficult for us to identify the truth from the appearance.
