18650 lithium battery is a type of lithium-ion battery, which is the originator of lithium-ion battery. There are many situations where the 18650 battery cannot be charged, and different problems need to be repaired accordingly, so as to solve the problem of the 18650 battery not being charged. So what are the reasons and treatment methods for the battery not being charged?

The possible reasons why the 18650 lithium battery cannot be charged are as follows:
Poor battery connection: If the contact between the battery and the charger is poor, the battery cannot be charged. At this time, you need to check whether the contact between the battery and the charger plug is good, or try to replace the charger and battery.
Incorrect battery polarity: If the battery is reversed into the charger, it will also cause the battery to fail to charge. The correct operation is to connect the positive electrode of the battery to the positive electrode of the charger, and the negative electrode of the battery to the negative electrode of the charger.
Charger failure: If the charger itself fails, it will also cause the battery to fail to charge. At this time, the charger needs to be replaced to solve the problem.
Battery aging: If the battery has been used for a long time, the battery capacity may have decreased, and the internal resistance of the battery may increase, which will cause the battery to fail to be fully charged. At this time, a new battery needs to be replaced.

Insufficient charging voltage: If the output voltage of the charger is insufficient, the battery will not be fully charged. At this time, it is necessary to check whether the output voltage of the charger meets the requirements of the battery.
In short, if the 18650 lithium battery cannot be charged, it is necessary to check the battery connection, polarity, charger, battery aging and other factors, find the problem and repair or replace the equipment.
