How to repair mobile phone lithium battery

About the repair method of mobile phone lithium battery Generally speaking, there are three common repair methods for mobile phone lithium battery. The important reasons for repairing mobile phone lithium batteries are as follows: For example, the talk time of each call is very short; for example, the cost of answering or dialing about 10 times is dangerous, and so on. The purpose of maintenance is to make the lithium battery life longer. The cycle life of mobile phone lithium battery is about 600 times. Due to the repeated charging of the battery, the internal molecular arrangement microstructure is gradually destroyed, and the charging storage efficiency is gradually reduced. In fact, maintenance of lithium batteries is very necessary when long-term maintenance is not permanent. 1. The short lithium battery is fully discharged and then recharged to activate the battery; this is to achieve deeper charging by using the internal power supply, which requires some unconventional methods. When the battery voltage is lower than the rated voltage of 3.6 volts, recharging after discharging can last longer. 2. Use plastic packaging for the mobile phone lithium battery, rest as much as possible in the package, there are three layers to ensure that the battery is in a vacuum state, and then, once again, the food film is covered with three layers of newspaper, the lithium battery is completely sealed, and the refrigerator is frozen for 48 hours Then, take out the battery and wrap it with six layers of paper film. The lithium battery has no frozen surface caused by expansion and deformation. After cooling for a period of time, recharge. 3. Use a clean eraser or other cleaning tools to gently wipe the lithium battery and the metal contacts on the phone to help the phone battery charge and maintain power. The purpose of these processes is to easily destroy the internal structure of the original battery, and the ability to be responsible may be added in a short period of time, but long-term use is not necessarily effective. Once the microstructure of the lithium battery is destroyed, it is impossible to completely recover. Long-term use of this method accelerates the depletion of mobile phone batteries. Relevant experts pointed out that it is not feasible to take repairs. Now that the price of lithium batteries is falling, why do they need to be repaired? The above methods may not be effective for repairs, so buying mobile phone rechargeable batteries is the best choice.
