　　18650 lithium ion battery repair method

　　1. Remove all your 18650 lithium-ion 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. When the electricity is turned on, use this method to release part of the memory electricity. When winter comes, put it outside for a while, and then bring it inside.

　　Low temperature high energy density 18650 3350mAh-40℃ 0.5C discharge capacity ≥60%

　　Charging temperature: 0~45℃ Discharging temperature: -40~+55℃ Specific energy: 240Wh/kg -40℃ discharge capacity retention rate: 0.5C discharge capacity≥60%

　　2. There is another method, remove the battery, put it for about a week, and consume the electricity slowly, first use the machine to completely consume the electricity. 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-ion 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.
