　　18650 lithium battery repair method

　　1. Take out all your 18650 lithium batteries and treat them with temperature. The battery will greatly shorten the use time when the temperature is unstable, because the battery is dead and a considerable part of the lithium ion has memory. In order to use this method to release part of the memory electricity, when winter comes, put it outside for a while, and then bring it inside.

　　2. Another method is to remove the battery, put it for about a week, and consume the electricity slowly. You need to use the machine to completely consume the electricity first. Then charge it fully again. I guess your current charging time must be very short. After charging fully, disconnect and charge again. Repeat several times, it will definitely be effective.

　　3. In order to fully activate the 18650 lithium battery, it needs to be fully charged and discharged several times. The discharge circuit is composed of resistors and light-emitting diodes, and the state of discharge can be estimated through the light-emitting diodes.
