Five professional identification methods for lithium battery

Five professional identification methods for lithium battery

Page view
Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate, and performance-price ratio are superior to those of lithium-ion batteries. The ithium battery manufacturer tells you that due to its own high technical requirements, only a few companies in the country are producing this type of lithium metal battery.

good price and quality ithium battery products
1. Investigate battery performance.
Usually standby time and talk time are a relative concept. The ithium battery manufacturer tells you that for consumers, the capacity of the battery is the comprehensive use time, that is, the standby time and the talk time. In short, the rated capacity of the battery should not be less than 95% of the standard capacity, it should be fully charged for 28 days, the minimum capacity should not be less than 60% of the rated capacity, and the battery's service life should not be less than 400 times. If the battery does not meet the above standards, it can be judged as a fake.
2. Use special tools to identify anti-counterfeiting signs.
Ithium battery manufacturers tell you that in the face of more and more types of mobile phone batteries on the market, as well as more and more complex anti-counterfeiting technologies, some large companies are constantly improving their anti-counterfeiting technologies. Therefore, with the improvement of anti-counterfeiting technology, it is difficult for people to distinguish the authenticity of the battery from the appearance.
3. Use a dedicated detector to identify the battery.
From the appearance alone, the quality of a mobile phone is difficult to distinguish between good and bad. Therefore, a mobile phone battery tester has been launched on the market, which can detect and judge the capacity and quality of lithium, nickel-metal hydride, nickel-cadmium and other batteries with a voltage of 2k-6.0V and a capacity of less than 1999 mAh. It has activation and charging capabilities. And discharge function. The whole process is controlled by the micro lithium battery according to the characteristics of the battery, which can realize the digital display of the measured technical parameters such as voltage, current, and capacity.
4. Observe abnormal charging conditions.
Generally, a genuine mobile phone battery must have an over-current protector inside, which will automatically cut off the circuit when the external short circuit causes the current to be too large to avoid burning or damaging the mobile phone. In addition, the lithium battery has an overcharge protection circuit, which will automatically cut off the power when non-standard electrical appliances are used and the AC current is too large. If during the charging process, the battery is found to be seriously hot or smoke, or even explode, it means that the electrical grounding is fake.
5. Check the battery identification.
The manufacturer of ithium battery tells you the national regulations that the outer packaging of mobile phone batteries should clearly indicate the trademark, factory name and address, battery positive and negative electrodes, rated capacity and material. The rated capacity is an important factor in measuring the price of mobile phone batteries. If there is no mark or the mark is incomplete, it is considered defective.
Ithium battery manufacturer tells you that in addition, the logo of the real battery is pasted with super glue, which is not easy to tear off. On the other hand, the fake battery may tear off the entire label as soon as it is torn.
