How To Identify Lithium Batteries

1. Compare the size of the battery capacity. The general cadmium-nickel battery is 500mAh or 600mAh, and the nickel hydrogen battery is only 800-900mAh; The capacity of lithium-ion mobile phone batteries is generally between 1300-1400mAh, so the time when lithium batteries are fully charged is about 1.5 times that of nickel hydride batteries and about 3.0 times that of cadmium-nickel batteries. If you find that the lithium-ion mobile phone battery block you purchased does not work for as long as advertised or specified in the manual, it may be counterfeit.

2. Look at the plastic surface and plastic material. Genuine batteries have uniform anti-wear surfaces, made of PC material, and have no embrittlement; Counterfeit batteries have no anti-wear surface or are too rough, and are made of recycled materials that are prone to brittleness and cracking.

3. Measure the charging voltage of the battery block. If you use cadmium-nickel and nickel hydride battery blocks to counterfeit lithium-ion mobile phone battery blocks, 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 or nickel-hydride battery.

4. For the original battery, the surface color and texture of the battery are clear, uniform, clean, and there are no obvious scratches and damage; The battery logo should be printed with the battery model, type, rated capacity, standard voltage, positive and negative pole marks, and the name of the manufacturer. The feel should be smooth and unobstructed, the elasticity should be appropriate, the hand should cooperate well, and the lock should be reliable. There are no obvious scratches and blackening and greening of the hardware. If the purchased mobile phone battery does not match the above phenomenon, it can be preliminarily concluded that it is a fake.

5. Many mobile phone manufacturers also start from their own perspective and improve the difficulty of counterfeiting mobile phones and their accessories by striving to improve the level of craftsmanship, so as to further curb the proliferation of counterfeit parallel goods. Generally, regular mobile phone products and their accessories require consistency in appearance. Therefore, if you install the purchased mobile phone battery, you should carefully compare the body and the battery bottom case, if the color is the same, it is the original battery. Otherwise, the battery itself is dull and dull, and it may be a fake battery.

6. Observe the abnormal condition of charging. Generally, there should be an overcurrent protector inside the genuine mobile phone battery, which will automatically cut off the circuit in the case of excessive current caused by an external short circuit, so as not to burn or damage the mobile phone; Lithium-ion batteries also have an overcurrent protection line, when using irregular electrical appliances, when the alternating current is too large, it will also automatically cut off the power supply, resulting in failure to charge, and can automatically return to the conduction state under normal conditions of the battery. If, during the charging process, the battery is found to be seriously hot or smoked, or even exploded, it means that the battery must be fake.

7. With the help of specialized tools. In the face of more and more types of mobile phone batteries on the market, and counterfeit technology is becoming more and more sophisticated, some large companies are also constantly improving anti-counterfeiting technology. With the improvement of anti-counterfeiting technology, it is difficult to distinguish between true and false from appearance.
