The 18650 lithium battery is a type of lithium-ion battery and a pioneer of lithium-ion batteries. There are many situations where the 18650 battery cannot be charged, and it is necessary to take corresponding repair methods to effectively solve the problem that the 18650 battery cannot be charged. So what are the reasons and solutions for the battery not charging?

충전이 안되는 18650 리튬 배터리

The possible reasons why the 18650 lithium battery cannot be charged are as follows:

Poor battery contact: If the battery is not in good contact with the charger, the battery cannot be charged. At this time, you need to check whether the battery is in good contact with the charger plug, or try to replace the charger and battery.

Incorrect battery polarity: If the battery is inserted backwards into the charger, the battery will also not charge. The correct operation is to connect the positive terminal of the battery to the positive terminal of the charger, and the negative terminal of the battery to the negative terminal of the charger.

Faulty charger: If the charger itself fails, it can also prevent the battery from charging. At this time, the charger needs to be replaced to solve the problem.

Battery aging: If the battery is used for a long time, the battery capacity may decrease, and the internal resistance of the battery may increase, resulting in the failure of the battery 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 point, 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, multiple factors such as battery connection, polarity, charger, and battery aging need to be checked to find out the problem and repair or replace the device.
