What are the methods to identify lithium battery products?

Lithium battery product identification method 1. Check the anti-counterfeiting label to see if there is an anti-counterfeiting label. Generally speaking, most brand batteries will put an anti-counterfeiting label on the docking part of the battery shell before leaving the factory. Therefore, when purchasing, pay attention to see if the anti-counterfeiting label is well pasted. If necessary, you can also scratch off the anti-counterfeiting label password coating to verify the authenticity. Finally, pay attention to the processing date printed on the lithium battery. 2. Charging process inspection method Generally, there should be an over-current protector inside the genuine lithium battery. In the case of excessive current caused by an external short circuit, the circuit will be automatically cut off to avoid burning or damaging the electronic products. The lithium battery also has an overcharge protection circuit, which will automatically cut off the power when using non-standard electrical appliances and excessive AC current. If the battery is found to be severely heated or smoke or even explode during the charging process, it means that the battery is fake . 3. The performance identification method is used to investigate the performance of the battery. Generally, the working time of the battery is a relative concept. The rated capacity of the battery should not be less than 95% of the standard capacity. Less than 400 times; if the battery does not meet the above standards, it can be judged to be a fake. 4. The appearance of all genuine lithium batteries should be neat, without extra burrs, the outer surface has a certain degree of roughness and feel comfortable; the inner surface feels smooth, and fine longitudinal scratches can be seen under the light. The battery electrode has the same width as the cell phone battery sheet, and the corresponding position under the battery electrode is marked with [+] and [-]. The isolation material of the battery charging electrode is the same as the shell material, but it is not integrated. 5. Comparing the size of the battery capacity The general nickel-cadmium battery is 500mAh or 600mAh, and the nickel-hydrogen battery is only 800-900mAh; and the capacity of the lithium-ion mobile phone battery is generally between 1300-1400mAh, so the lithium battery is fully charged. The time is about 1.5 times that of nickel-hydrogen batteries and about 3.0 times that of nickel-cadmium batteries. If it is found that the working hours of the lithium-ion mobile phone battery block you have purchased is not advertised or specified in the manual, it may be a counterfeit.
