What are the common repair methods for lithium battery mobile phones?

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 that is used for automatic shutdown with plastic wrap, and try to be as compliant as possible when wrapping it. 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. Lithium battery manufacturers remind that the price of lithium batteries is not too high. Instead of laboriously repairing lithium batteries, it is more convenient and cost-effective to buy a new battery. In addition, developing good usage habits is also a shortcut to extend the life of lithium batteries.
