There are many situations in which the 18650 lithium-ion battery cannot be charged into the battery. Different problems require corresponding repair methods to solve the problem of the 18650 lithium-ion battery not charging. So what are the situations when the 18650 lithium-ion battery cannot be charged? What other solutions are there?

1. The electrode contacts of the 18650 lithium-ion battery are dirty, the contact resistance is too large, and the voltage drop is too large. When charging, the host thinks that it is fully charged and stops charging;

2. The internal charging circuit is faulty and cannot be charged normally; when the battery is assembled, the consistency error of the cells is too large. At the beginning of use, the problem is not big, but after a certain number of cycles, this error will cause the battery to lose more cells. Using performance, it is possible that most or all of them will eventually be scrapped. This also only replaces the battery

3. The 18650 lithium battery has an internal failure. It is very likely that the battery protection board circuit failure or software failure is caused by inattentive use. This is basically impossible to repair. It is recommended to replace the battery. Of course, if you are a professional and have the corresponding maintenance tools, you can also buy a suitable battery protection board for the replacement.

4. The temperature environment during charging is too high. Generally, 18650 lithium-ion batteries will have a temperature protection mechanism. If the temperature is too high, the protection will be triggered, resulting in failure to charge. The battery can be placed within the allowable charging temperature range. If not, it may be due to When the battery is running at a high temperature, the separator in the battery cell will break down, short circuit, or other chemical reactions, making the battery unusable. This just replaces the battery.

18650 lithium-ion battery can not charge the solution

1. If The charger interface is aging or the charger itself is damaged, replace it with a new charger for testing.

2. The metal of the charging hole is oxidized to cause poor contact, which is a hardware failure. It is necessary to contact the after-sales service for detailed inspection and maintenance.

3. If there is a problem with the quality of the charging cable, replace it with a new one.

4. The battery itself has expired or been damaged, and the battery can be replaced directly.
