Analysis of 18650 lithium battery and lithium battery pack repair

18650 lithium battery repair method 1. Remove all your batteries after they are used up, and use temperature to solve the problem. The battery will greatly shorten the use time when the temperature is unstable, because the battery has no electricity and a considerable part of the lithium ion has been taken. If you have a memory battery, you can use this method to release a part of the memory battery. When winter comes, you can put it outside for a while, and then go inside the house. 2. Remove the lithium battery, leave it for about a week, and slowly consume the electricity, first use the machine to completely 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, repeating it several times, it is absolutely effective. Repair method of lithium battery pack ◆Discharging lithium 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 battery packs for current limiting. First, use a small current to activate, make the control loop alternating current to tens of milliamperes, and maintain it for 30 to 60 minutes, and then increase the current to 1 to 2 times the nominal value of the battery. ◆Lithium battery packs whose lifespan is about to be exhausted when changing batteries are actually the internal lithium batteries approaching the end of their lifespan, so we only need to replace the internal lithium batteries to bring the lithium battery pack back to life. The detailed operation is as follows: Use a utility knife to cut along the seam of the battery shell. If you encounter the barbed buckle, do not solve it first, wait until the remaining seams are open, and then pinch the shell on the side of the barb to loosen the buckle. After opening the casing, use an electric soldering iron to remove the lithium batteries, and then use this as a sample to buy the lithium batteries of the corresponding specifications and quantities in the electronic market. Then weld the newly purchased lithium battery cell to the original battery as it is, and then apply molten hot melt adhesive on the inside of the battery joint, and then quickly close, align and compress the shell, and use the pod after the hot melt adhesive has solidified. The hot-melt glue overflowing from the joint was repaired with a tool knife, and the repair of the lithium battery pack is now complete.
