Analyze three ways to revive lithium batteries

A way to restore the lithium battery I'm sure we have all experienced this: your phone flashes full after being flushed, and it is low on standby, and then shuts down after a call. Charging will soon be full of flashes and cycles. It always brings us a lot of inconvenience. In order to save our money, here are three ways to correct the lithium battery problem. Although I can’t drink a new lithium battery for comparison, it’s good now, we can learn! When the mobile phone’s lithium battery starts to age, it usually shows that the lightning is normal when the mobile phone is empty, and the battery power indicator is full, but the standby time is short, and one call It will automatically shut down, and the flash is full while charging. This battery can be tested in the following ways. Lithium battery resurrection method 1: Freeze (user experience) A lithium battery is broken, the symptom is that it can't be charged, and the camera can't be turned on (the camera flashes for a few times and the battery is dead). I have no choice but to throw it away and throw it in the trash can. Later, I didn’t know what I thought. The battery, multi-layer absorbent paper and multi-layer plastic film were sealed in the refrigerator and frozen (-18 degrees) for two days and two nights, and even after packaging, it was at room temperature for two days, so I was unwilling to put it. Go to the camera and try again, hey, even completely back to normal! Now tell everyone, if you have a similar situation, you might as well give it a try! There are two other ways: lithium battery resurrection method 2: discharge and discharge power can be used to connect the resistance method. When starting up and discharging, the mobile phone should be placed at the level of shutdown; the connection resistance discharge can be used to connect the small beads with the corresponding voltage for long-term discharge, until the small beads are connected to the level of instantaneously extinguishing. It is best to have a high discharge current. Lithium battery resurrection method 3: activate 12V alternating current in series, and a small string of beads or resistors in series between the batteries to limit the current. First select a small current to activate, make the alternating current in the control circuit tens of milliamps, hold for 30 to 60 minutes, and then increase the current to 1 to 2 times the nominal value of the battery. For example, if a 1000 mAh battery is added to 1000~2000 mAh, it will be activated for 30~60 minutes. During the above process, the temperature and appearance of the battery should be observed: there should be no abnormal phenomena such as heating, smoking, flatulence, etc., if the temperature is too high (above 40°C), the current should be appropriately reduced. Lithium batteries through the above activation process can generally operate normally, but they cannot be compared with new batteries!
