Do you know how to repair the lithium battery pack?

1. Use a clean eraser or cleaning tools of other materials to gently wipe the metal contacts on the lithium battery and the metal contacts on the mobile phone, which will help the charging status and the long-lasting power. 2. Wrap the old mobile phone lithium battery pack that is used to automatically shut down with plastic wrap, and try to be as compliant as possible when wrapping, there are three layers inside and outside to ensure that the battery is in a vacuum state. Then, wrap three layers of newspaper outside the plastic wrap to completely seal the lithium battery. Put it in the freezer layer of the refrigerator, after 48 hours, take out the batteries, and remove the six layers of paper film one by one. The lithium battery has no surface expansion or deformation due to freezing. After cooling for a period of time, then charge. 3. Let the lithium battery that is close to being scrapped completely discharge, and then recharge the battery to activate it. The specific method is: deep discharge of the mobile phone is to achieve a deeper recharge by depleting the internal electric energy, which requires some unconventional methods. After all your batteries are used up, remove them and treat them with temperature. When the temperature is unstable, the lithium battery will greatly shorten the use time, because the battery has no electricity, and a considerable part of the lithium ion already has a memory battery. In this way, part of the memory battery can be released. Winter is here, put it outside for a while, and then take it to the house. There is another way to remove the lithium battery pack and leave it for about a week to consume the electricity slowly. You must 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. Repeat a few times. It is absolutely effective. The specification of the lithium battery pack for electric vehicles is 48v20AH, which can be charged and repaired with a 60V20AH battery charger; the 48v12AH lithium battery pack can be charged and repaired with a 48v20AH battery charger. Repairing lithium batteries with hot air from dry cleaners, the majority of electric vehicle users are aware that electric vehicles are not far away, and need to add distilled water to maintain and repair the batteries.
