The repair methods of mobile phone batteries are low temperature repair and plastic film repair.
1. Low temperature repair
Placing your cell phone in a low temperature environment can change the electrolyte inside the lithium battery and promote chemical reactions. the newly frozen battery. The process of using a lithium battery is actually a process of charging and discharging. During this time, the negative and positive charges of the battery collide. The reason why batteries become less and less durable is that at normal room temperature, the internal kinetic energy of electrons is relatively large, so the battery is in an active state and leakage is relatively frequent.
2. Plastic film repair
Wrap the old lithium battery of the mobile phonei turns off automatically with plastic wrap. Try to wrap it as tightly as possible, with a total of three layers inside. and outside. Make sure the battery is under vacuum. Then wrap three layers of newspaper outside the plastic film to completely seal the lithium battery. Place it in the freezer layer of the refrigerator. After 48 hours, remove the battery and remove the six layers of wrapping paper. The lithium battery does not exhibit any expansion or surface deformation due to freezing. After cooling for a while, then charge.
Precautions for using mobile phone batteries
1. Do not wait until the battery is exhausted before charging it; excessive discharge will have some impact on the battery. In severe cases, the device may not start normally. Try to charge it in time when the battery is too fweak.
2. It is recommended to use original chargers and data cables for charging; Non-original chargers may have various problems, which can damage the battery and shorten its lifespan.
3. When loading, try not to play while loading. At this time, it is easy to increase the heat, easily consume the battery and shorten its life.
4. After charging is completed, please disconnect the power supply in time to avoid prolonged charging.
5. Avoid using the device in high temperature environments, as this can easily damage the battery.
The storage capacity of lithium batteries has decreased. Can the battery really be restored after freezing?
No
The battery can be used in sub-zero environments, and the laptop can certainly be used in Antarctica. It's the raison.
According to data, lithium batteries can work normally in the range of -40°C to +75°C. The capacity at -40°C is about 50% of the capacity at normal temperature, showing extremely excellent performance at high and low temperatures.
The ThinkPad manual says that the battery should not be heated above 100 degrees.
So, to summarize, it definitely won't explode if placed in the refrigerator
The lithium battery has not been charged for a long time and needs to be recharged now. In the event of a power outage, would it be helpful to wrap it in newspaper and put it in the refrigerator for two or three days? Can it get better? Or only in brief
not.
The freezing method is only suitable for recovery when the battery is not damaged. It has a certain effect. However, this can only be used in case ofe problem with your battery during activation.. If the battery itself is faulty and cannot be recovered by freezing, you can use Master Lu to check the actual storable power of your battery before freezing it. Be sure to empty the battery in case of freezing.
Precautions for lithium batteries
When using lithium batteries, it should be noted that the battery will enter a dormant state after being left for a period of time . is lower than the normal value and the usage time will also change accordingly. However, lithium batteries are easy to activate. After 3-5 normal charge and discharge cycles, the battery can be activated and restored to its normal capacity.
Due to the characteristics of the lithium battery itself, it has almost no memory effect. Therefore, the new lithium battery of the user's mobile phoner does not require special methods or equipment during the activation process. Not only is this true in theory, but from my own practice, the "natural activation" method of loading using standard methods from the beginning is best.
This method is useless.
The correct method is: charge for half an hour, whether charged or not, unplug the charger, wait for a few minutes, then charge continuously for 12 hours.
If the battery has the possibility of being repaired, it will be reactivated. If the battery is worn out, it will not work.
