What is the external reason why the battery cell of polymer lithium ion battery cannot be charged?

External reasons why the battery core of polymer lithium ion battery cannot be charged 1. The charger and the battery are not matched, especially the difference in the charging current design of the unmatched charger and the lithium ion battery will cause the instantaneous current to be too large during charging, and the lithium ion The battery performs over-current protection to stop charging. To solve this kind of non-matching, especially pay attention not to mix the Ni-MH charger with the high-capacity lithium-ion battery charger. Some universal chargers should not be used universally. If you are not sure, you can also check the important advantages of commonly used lithium-ion batteries. It is better to choose the charger according to the characteristics. 2. The charging equipment is faulty and there is no output voltage. If this happens, just put the battery on another charger of the same model to charge it. 3. Unsuitable charging environment. Both the charger and the rechargeable battery have their own working environment. If any one of the two restrictions is exceeded, no matter whether it is high temperature or low temperature, charging will not be possible. Solving the problem of not charging the polymer lithium ion battery cell is nothing more than diagnosis and treatment. The order of diagnosis is the first external cause and then the internal cause, because the problem of the charging method only needs to be corrected, and the internal cause requires professional battery knowledge and battery testing equipment to reach the correct conclusion. If you can’t solve it, you can get a professional Maintenance outlets for maintenance. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
