When the lithium battery of the mobile phone begins to age, the display voltage is generally normal when the mobile phone is empty, and the battery power indicator is basically full, but the standby time is short.(A call will automatically shut down; When charging, quickly show that the battery is full). This type of battery can be activated in the following ways!
First, 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.
Second, activate. 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!
