What are the reasons for 18650 lithium battery not charging and how to deal with and repair

1. The internal charging circuit is faulty and cannot be charged normally. 2. There is an internal failure of the 18650 lithium battery. 3. The battery electrode is dirty, the contact resistance is too large, and the voltage drop is too large. When charging, the host is considered to be full and stop charging; the 18650 battery cannot be charged. Treatment methods: 1. The charger interface is aging or the charger itself is damaged. Replace with a new charger for detection. 2. There is a problem with the quality of the charging line. Replace with new pipeline. 3. The metal in the charge hole is oxidized, resulting in poor contact, which is a hardware failure, and specific maintenance should be carried out after the sale. The battery itself is exhausted or damaged. Replace the battery straight away. 18650 lithium battery repair method: 1. After the battery is fully used, remove the battery and use the temperature for production. When the temperature is unstable, the battery can greatly shorten the use time, because the battery has no electricity, and a large part of the lithium ion has memory , So you can release part of the memory power outside for a period of time in winter, and then return to the house. 2. Another way is to remove the battery and put it aside for about a week, so the power consumption will be slow. It has to be completely consumed by the machine first. Then make full use of it. It is estimated that your current charging time must be very short. When it is full, it will be cut off and repeated several times. It must be effective.
