Three lithium battery repair methods

There are three ways to repair the lithium battery. When the mobile phone lithium battery starts to age, the general performance is that the voltage is normal when the phone is empty, the battery power indicator is full, but the standby time is short, the call will automatically shut down, and the charging will soon appear to be full . This battery can be modified in the following ways. Lithium battery calibration method 1: Discharge can be energized or connected by resistance. The discharge on the power supply should be placed on the stop level of the power supply of the mobile phone; the resistance discharge can be discharged with the beads of the corresponding voltage for a long time, until the beads are connected to the degree of instantaneous extinguishment. It is best to have a high discharge current. Lithium battery calibration method 2: Activate 12V alternating current in series, and a small bead or resistor in series between the batteries to limit the current. First, select a small current to activate the control loop, make the AC current tens of milliamps, and maintain it for 30-60 minutes, and then increase the current to 1-2 times the nominal value of the battery. For example, if a 1000 mAh battery is added to 1000 to 2000 mAh, it lasts for 30 to 60 minutes. In the above process, pay attention to the temperature and appearance of the battery: there should be no abnormal phenomena such as heating, smoking, flatulence, etc., such as high temperature (above 40°C), and the current should be appropriately reduced. The lithium battery after the above activation process can be used normally, but it cannot be compared with the new battery! Lithium battery correction method 3: freezing (user experience) A few days ago, one of my lithium batteries was broken, and my symptom was that it could neither be charged nor recharged. I can't turn on the camera (the camera is broken), I tried it several times. There is no choice but to throw it away. It was almost thrown into the trash can. Later, I didn’t know what it was. I sealed the battery with multilayer absorbent paper and multilayer plastic film in the freezer room (minus -18 degrees) and froze for two days and two nights. After putting the bag at room temperature, the heart again Unwilling to try the camera, hey, it has been completely restored to normal! Now tell everyone, if there is a similar situation, you may wish to give it a try!
