Introduction of 18650 lithium ion battery pack repair method

Repair method of 18650 lithium ion battery pack ◆Discharging 18650 lithium ion battery pack can adopt the method of starting up and discharging or connecting resistance. The power-on discharge should be placed to the extent that the mobile phone is turned off immediately; the resistance discharge can be used to connect the small bulb of the corresponding voltage to discharge for a long time, until the small bulb is connected to the extent that it will go off instantly. The discharge current is preferably a large current. ◆Activate the 12V alternating current in series, and connect a small electric bead or resistor in series between the lithium-ion battery packs for current limiting. First, use a small current to activate, make the control loop alternating current to tens of milliamperes, maintain it for 30 to 60 minutes, and then increase the current to 1 to 2 times the nominal value of the battery. ◆The 18650 lithium-ion battery pack whose life is almost exhausted when the battery is replaced is that its internal lithium battery is close to the end of its life. Therefore, as long as we replace the internal lithium battery, the 18650 lithium-ion battery pack can be reborn. 18650 lithium-ion battery packs are often unusable because one or a group of batteries are damaged. At this time, the voltage and capacity of each battery should be measured one by one. There is no voltage or the voltage is seriously low, and the capacity or discharge time is quite different. Take it apart and replace a battery with a similar capacity and internal resistance. 18650 Li-ion battery pack battery consumption should be detected in time and solved immediately to avoid danger. You should also choose a regular battery manufacturer. For example, the lithium-ion battery pack produced by Energy Storage is actually very safe, and the battery usage rate of the lithium-ion battery pack is very high. 18650 Lithium-ion battery repair method 1. Remove all your batteries after they are used up, and treat them with temperature. When the temperature is unstable, the battery will greatly shorten the use time, because the battery has no electricity and a considerable part of the lithium ion has been If you have a memory battery, you can use this method to release a part of the memory battery. When winter comes, put it outside for a while, and then go inside the house. 2. There is another way to remove the battery, leave it for about a week, and slowly consume the electricity, first use the machine to fully consume the electricity. Then charge it all again. It is estimated that your current charging time must be very short. After the charge is full, disconnect it and charge it again. Repeat a few times. It is absolutely effective. 3. In order to fully activate the 18650 lithium-ion battery, it is necessary to charge and discharge it 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.
