Compare the battery capacity. General cadmium nickel battery is 500mAh or 600mAh, nickel hydrogen battery is 800-900mah; The capacity of lithium-ion mobile phone battery is generally between 1300-1400mah, so the time of lithium battery after full charge is about 1.5 times that of nickel hydrogen battery, and about 3.0 times that of cadmium nickel battery. If it is found that the lithium ion mobile phone battery you buy does not work as long as advertised or specified in the manual, it may be counterfeit.
Look at the plastic surface and plastic material. Genuine battery anti-wear surface uniform, the use of PC material, no brittle phenomenon; Counterfeit batteries have no anti-wear surface or are too rough, using recycled materials, easy to crack.
Measure the charging voltage of the battery block. If a nickel-cadmium or nickel-hydrogen battery block is used as a fake lithium-ion mobile phone battery block, it must be composed of five 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 less than 8.0V, it may be nickel-cadmium, nickel-hydrogen battery.
For the original battery, its battery surface color and texture is clear, uniform, clean, no obvious scratches and damage; The battery mark shall be printed with the battery model, type, rated capacity, standard voltage, positive and negative pole marks and manufacturer name. Feel should be smooth without obstruction, suitable for tightness, good with the hand, reliable lock; No obvious scratches, black and green metal pieces. If we buy the mobile phone battery and the above phenomenon does not conform to, can be preliminarily concluded that it is fake.
Many mobile phone manufacturers also from their own point of view, through efforts to improve the technological level, to improve the mobile phone and its accessories counterfeiting difficulty, so as to further curb the phenomenon of fake goods flooding. General formal mobile phone products and accessories must be consistent in appearance. Therefore, if we buy back the mobile phone battery loaded, should carefully compare the body and battery chassis, if the color and dark consistent, is the original battery. Otherwise, the battery itself is dull, it may be a fake battery.
Observe abnormal charging conditions. In general, genuine mobile phone battery internal should have over current protector, in the case of external short circuit caused by excessive current, automatically cut off the loop, so as not to burn or damage the mobile phone; Lithium ion battery also has overcurrent protection line, when the use of non-standard electrical appliances, the current is too large will automatically cut off the power supply, resulting in no charge, in the normal condition of the battery, can automatically restore to the status of conduction. If, in the process of charging, we find that the battery is seriously heating up or smoking, or even exploding, the battery must be fake.
Use special tools. Faced with a growing variety of mobile phone batteries on the market, and increasingly sophisticated counterfeit technology, some big companies are improving their anti-counterfeiting techniques. With the improvement of anti-counterfeiting technology, it is difficult for us to distinguish the real from the fake from the outside.
