Analysis of the product discrimination method of lithium battery

1. Check the anti-counterfeiting label The lithium battery manufacturer proposes to see whether there is an anti-counterfeiting label is the key. Generally speaking, most brand batteries will have an anti-counterfeiting label attached 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. 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 Lithium battery manufacturers say that in general, genuine lithium iron phosphate batteries should have an overcurrent protector. In the case of excessive current caused by an external short circuit, the circuit will be automatically cut off to avoid burning or damaging electronic products. The lithium battery also has an overcharge protection circuit, and it will automatically cut off the power when using non-standard electrical appliances or excessive AC current. 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. Lithium battery manufacturers tell us how to identify battery performance. Usually battery working time is a relative concept. The rated capacity of the battery should not be less than 95% of the standard capacity, and the minimum capacity of the battery should not be less than 60% of the rated capacity for 28 days. , The battery life is no less than 400 times; if the battery does not meet the above standards, it can be judged to be a fake. 4. Lithium battery manufacturers analyze that all genuine lithium batteries should be neat and tidy in appearance, without burrs, and have a certain roughness on the outer surface 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 you find that the working hours of the lithium-ion cell phone battery block you have purchased is not advertised or specified in the manual, the lithium battery manufacturer may say that it may be a counterfeit. Lithium battery manufacturers often overlook a small detail when distinguishing true and false batteries, that is, the battery contacts. Because all kinds of brand-name real cell phone batteries, their contacts are mostly annealed and should be matte rather than shiny. Based on this, the authenticity of the cell phone battery can be preliminarily determined. In addition, we 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 pure golden yellow and reddish. Or it may be fake. Disclaimer: Some pictures and content of articles published on this site are from the Internet, please contact to delete if there is any infringement.
