1. Observe the fineness of the lithium-ion battery's appearance of lithium-ion batteries and the degree of neatstream of its quality workmanship or certain feedback. Producing a well-known lithium-ion battery, the overall appearance is also a regular, the material workmanship is the same.
Because the lithium-ion battery needs to protect its own safety quality, only the fine equipment is manufactured to make the difference in material components and shapes during the production process. 2. Check the hardness of the lithium-ion battery can be handled with a lithium ion battery with a tool or a part of its intermediate.
If the hardness of the lithium-ion battery is moderate, there is no soft extrusion that the cell of the lithium-ion battery is a relatively high quality battery. 3, detecting lithium-ion battery internal resistance and maximum discharge current Checking the most rapid quality of lithium ion batteries is to detect the internal resistance and maximum discharge current of lithium ion batteries. Good quality lithium-ion battery, very small internal resistance, largest discharge current is large.
Using the multimeter directly shorts two electrodes of the lithium-ion battery, current should generally be in a certain value, even higher, and can maintain a relatively stable in a certain period of time. 4. Continued discharge of lithium-ion batteries Observe in the process of lithium ion battery, continued to discharge for 10 minutes, if the two poles of the lithium-ion battery are not hot, prove that the protection system of lithium-ion batteries is more perfect.
In general, the quality of lithium ion battery with high quality battery protection systems will not be too bad. 5. Perceive the weight of the lithium-ion battery to remove the lithium ion battery to sense whether the weight is sinking, if the weight has a certain thickness, which belongs to a high quality battery.
Lithium-ion batteries with bad quality are often unbreakable, and their detailed performance is very fast, and the time required for charging is shortened. That is, when charging, it is often not filled, and the charger will be filled, but when actually use, do the same thing, power exhaustion is more faster than before.
