Lithium batteries have the advantages of small size, large capacity, no memory effect, etc., in some uses simply replace the traditional NiMH rechargeable batteries and other batteries, many high-end products on the market are now selected from lithium batteries. However, due to the high price positioning of lithium batteries on the market, so the phenomenon of using counterfeit batteries to impersonate the original battery is incessant. The following lithium battery manufacturers to teach you a few tricks: lithium battery product differentiation approach.
Lithium battery manufacturers to teach you a few tricks: the product differentiation of lithium batteries. 1, check the security label, see if there is a security label is the key, generally speaking, most brands of batteries will be in the factory, in the battery casing docking place affixed to the security label. So pay attention to see if the security label is intact when you buy it, and if necessary, you can also scratch the security label code coating to verify the authenticity. Finally, we also need to pay attention to the production date of the lithium battery above the machine.
2, the charging process inspection method, the general genuine lithium battery internal overcurrent protector, in the case of external short-circuit and other causes of excessive current, the active blocking circuit to avoid burning or damage to electronic products. Lithium battery has another overcharge protection line, when the use of non-standard appliances, cross-current will also actively block the power supply, if the battery is found in the process of charging serious heat or smoke, and even explosions, it is clear that the battery is fake.
What are the ways to distinguish lithium battery products
3, functional identification methods to examine the battery function is usually a relative concept of battery working time, the additional capacity of the battery should not be less than 95% of the standard capacity, fully charged placed in 28 days capacity of at least 60% of the additional capacity, battery life of not less than 400 times; if the battery does not meet the above specifications, can be identified as counterfeit.
4, the appearance of all genuine lithium battery should be neat, no excess burr, the outer surface has a certain degree of roughness and feel comfortable; the inner surface feels lubricated, the light can be seen in the fine vertical scratches. Battery electrode and cell phone battery width is the same, the corresponding position below the battery electrode marked with [+], [-] mark, the battery charging electrode isolation material and shell material is the same, but not one.
5, compare the size of the battery capacity, the general cadmium-nickel battery is 500mAh or 600mAh, hydrogen-nickel battery is only 800-900mAh; while the capacity of lithium-ion cell phone batteries are generally between 1300-1400mAh, so the lithium battery is fully charged to use the moment is about 1.5 times the hydrogen-nickel battery, is about 3.0 times the cadmium-nickel battery. If you find that the working time of the lithium-ion cell phone battery you buy is not as long as advertised or as stated in the instructions, it may be counterfeit.
When we distinguish between real and fake batteries, we often overlook a small detail, that is, the battery contact piece. As a variety of brand-name real cell phone battery, their contact piece is mostly through the annealing process, should be matte, not shiny, so according to this point can initially determine the authenticity of the cell phone battery. In addition, we must also carefully observe the color of the contact piece, fake cell phone battery contact piece is often made of copper, so its color is red or white, while the real cell phone battery should be this pure golden yellow, red or white may be a fake.
The above is to introduce us to the product differentiation of lithium batteries, the use of fake lithium batteries due to low power and the need for frequent charging, counterfeit lithium batteries may also explode, so users must be careful when buying lithium batteries to beware of crooks swap batteries, carefully check the authenticity of the battery in the box.
