How to distinguish lithium battery products?

1. Check the anti-counterfeiting label to see if there is an anti-counterfeiting label. Generally speaking, most brand batteries will have an anti-counterfeiting label affixed to the docking part of the battery shell when they leave the factory. So when buying, pay attention to see if the anti-counterfeiting label is well pasted, and if necessary, you can also scratch off the anti-counterfeiting label's password coating to verify its authenticity. Finally, pay attention to the processing date printed on the lithium battery. 2. Charging process inspection method Generally, there should be an overcurrent 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 product. The lithium battery also has an overcharge protection circuit. It will automatically cut off the power when using non-standard electrical appliances and the AC current is too large. If the battery is found to be severely heated or smoked or even exploded during the charging process, it means that the battery is fake . 3. Performance identification method to investigate battery performance. Generally, battery working time is a relative concept. The rated capacity of the battery should not be less than 95% of the standard capacity. The minimum capacity of the battery should not be less than 60% of the rated capacity for 28 days. Less than 400 times; if the battery does not meet the above standards, it can be judged to be a fake. 4. All genuine lithium batteries should be neat and tidy in appearance, free of extra burrs, and have a certain roughness on the outer surface and feel comfortable to the touch; the inner surface is smooth to the touch, 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. When people distinguish between genuine and fake batteries, one small detail is often overlooked, that is, the battery contacts. Because the contacts of all kinds of brand-name real cellphone batteries are mostly annealed, they should be matte, not shiny, so based on this, the authenticity of the cellphone battery can be preliminarily determined. In addition, you must carefully observe the color of the contacts. The contacts of fake mobile phone batteries are often made of copper, so its color is red or whitish, while the real mobile phone battery should be this kind of pure golden yellow and reddish. Or it may be fake. Disclaimer: Some pictures and content of the articles published on this site are from the Internet. If there is any infringement, please contact to delete.
