Lithium battery repair method

When the lithium battery of the mobile phone begins to age, the display voltage is generally normal when the mobile phone is empty. The battery power indicator is basically full, but the standby time is short. When a call is made, it is automatically turned off and it is quickly displayed when charged. This type of battery can be repaired in the following way.

Lithium battery repair method 1: discharge

The method of starting discharge or resistance can be adopted. Boot discharge should be put on the mobile phone to stop the extent; The resistance discharge can take a long time to discharge the small bead connected to the corresponding voltage until the small bead is instantly extinguished. The discharge current is better than the large current.

lithium battery Repair Method 2: Activation

The 12V AC is connected in series, and a small bead or resistor is connected in series between the batteries to limit the flow. First, a small current is used to activate the control loop to tens of milliamps, maintain 30 to 60 minutes, and then increase the current to 1 to 2 times the nominal value of the battery. For example, the battery at 1000 mA is added to 1000 to 2000 mA and activated for 30 to 60 minutes. In the above process, attention should be paid to the temperature and appearance of the battery: there should be no abnormal phenomena such as hot, smoking, drum packs, etc.. If the temperature is too high(above 40 °C), the current should be appropriately reduced. Lithium batteries that have undergone the above activation treatment can generally be used normally, but they can not be compared with new batteries!

Lithium battery repair method 3: frozen(user experience)

A few days ago, I was unable to use a lithium battery. The symptoms were that I couldn't charge it and the camera couldn't open(the camera showed no electricity). I had no choice but to throw it aside and throw it into the trash can. Later, I did not know what the idea was. The battery was sealed with multi-layer absorbent paper and multi-layer plastic film in the refrigerator freezer(minus 18 degrees) for two days and two nights. After being removed, the package was placed in the room temperature for two days. day, The heart is not willing to reload the camera to try, hey, it is completely normal! I am telling you, if there is a similar situation, you may wish to try!
