What should I do if the 18650 battery cannot be charged?The solution to the inability to charge 18650 lithium-ion batteries can be approached from the following aspects:
1. In most cases, it is due to the fact that the battery itself is not an ultra-low temperature rechargeable battery application. When used in ultra-low temperature natural environments, the low internal temperature of the battery causes the internal resistance of the battery to freeze, resulting in a decrease in the mechanical and chemical properties of the internal resistance of the battery, leading to a sudden decrease in internal resistance and even failure. This area can be rotated to an appropriate temperature, and after a period of time, the rechargeable battery application will repair a portion of its working capacity. When used frequently, the rechargeable battery application will experience a more severe decay coefficient or billing due to ultra-low temperature lithium precipitation.
2. The application of 18650 lithium-ion batteries often experiences complete power outages, and it is said that excessive charging and discharging of batteries can lead to personal behavior that causes rechargeable battery applications to be unable to charge when the charging head is normal. This means that rechargeable battery applications are often in a high power consumption state, resulting in a rapid decay coefficient and a long service life. This requires battery replacement.
3. Due to common faults in the charging interface, short circuit faults can cause the customized protection board for
lithium-ion batteries in cars to open and maintain on its own, making it unable to charge and requiring repair.
4. There is a problem with the lithium-ion charging head of the battery car. It is recommended to check the charging head first.
