I believe we must have encountered this situation: just after the battery of the mobile phone display full grid, but standby for a while, the power is insufficient, or even a call on the automatic shutdown. Recharging soon shows up full, going round and round. It always brings us a lot of inconvenience. To save you money, here are three ways you can fix the problem. Although can't compare with the new lithium battery, but already very good, we can learn from!
When the mobile phone lithium battery began to aging, the general performance of the mobile phone no-load display voltage is basically normal, battery power indicator is basically full, but the standby time is short, a call will automatically shut down, charging will soon show full. Such batteries can be repaired in the following ways.
Lithium battery repair method one: freezing
A few days ago, one of my lithium batteries died, and the symptom was that I couldn't charge it or turn it on when I put it in the camera (the camera was dead), after several attempts. There's nothing I can do but throw it away, almost throw it in the trash. Later, I didn't know what I was thinking, so I put the battery sealed with multilayer absorbent paper and multilayer plastic film into the freezer (minus 18 degrees) of the refrigerator for two days and two nights. After taking out the battery, I put it in the room temperature for two days with the packaging. I was very willing to try it again in the camera. Tell everybody now, if have congener circumstance, might as well try!
There are two other methods:
Lithium battery repair method two: discharge
The method of starting discharge or connecting resistance can be adopted. Startup discharge should be placed on the mobile phone startup stop degree; Resistance discharge can be connected to the corresponding voltage of the small bead discharge for a long time until the small bead is connected to the instant that the degree can be. A high discharge current is preferred.
Lithium battery repair method three: activation
12V ac is connected in series, and a small electric bead or resistor is connected in series between batteries for current limiting. First use small current activation, so that the control loop alternating current is 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, a 1000 mah battery can be added to 1000~2000 mah and activated for 30~60 minutes. Observe the battery temperature and appearance. Ensure that the battery is not hot, smoking, or bulging. If the battery temperature is higher than 40 ° C, reduce the current. After the above activation treatment of lithium batteries can be used normally, but can not be compared with the new battery!
