I believe we must have encountered this situation:Just full of electricity, but standby for a while, the lack of power, and even a phone call automatically shut down. It always brings us a lot of inconvenience. In order to save money for everyone, here are three ways we can fix the above problems with lithium cell phone batteries. Although it can not be compared with the new lithium battery, but it is very good!
When the mobile phone lithium battery begins to age, it generally shows that when the mobile phone is unloaded, the display voltage is basically normal, but the standby time is short, and a call is automatically shut down. Such batteries can be repaired in the following ways.
Lithium battery repair method 1: frozen (user experience)
A few days ago, I couldn’t use a lithium battery. The symptom was that I couldn’t charge the battery and I couldn’t turn it on. I tried it several times. In the end, I had to give up and almost threw it into the trash. Later, I did not know what the idea was. The battery was sealed in multi-layered absorbent paper and multi-layer plastic film in the refrigerator freezer (-18 degrees Celsius) for a full two days. After being removed, the battery was placed in the room at room temperature for two days. Try it in the camera, hey, it’s completely back to normal! If you have the same kind of situation, give it a try!
Lithium battery repair method 2: activation
Connect 12V AC in series with a small bead or resistor in series between the batteries for current limiting. First, activate with a small current and make the control circuit AC tens of milliamps for 30 to 60 minutes, then increase the current to 1 to 2 times the nominal value of the battery. For example, a 1000 mAh battery is added to 1000-2000 mA and activated for 30-60 minutes. In the above process, observe the temperature and appearance of the battery: there should be no abnormal phenomenon such as hot, smoke, etc. If the temperature is too high (above 40°C), the current should be reduced properly. After the activation of the above-mentioned lithium batteries can generally be used normally, but can not be compared with the new battery!
