Cell phone battery repair method

1. Use a clean eraser or cleaning tools with other material wipe to gently clean metal contact and phone contact of lithium battery, which is do good to charging condition and lasting power.

The lithium battery fixes a principle: long time use lithium battery of metal surface will have a certain degree of oxidation, mobile phone battery with phone contact is bad, lithium-ion batteries use time shorter, and use a rubber polishing or other clean tool can erase rust on the surface of the material, let the battery and mobile phone contact.

2. To use automatic shutdown of the old cell phone lithium battery firmly wrapped with plastic wrap, break, as far as possible when the parcel inside and a total of three layers, ensure the battery in the vacuum state. Outside the plastic wrap, then bread three layers of the newspaper, the li-ion battery completely sealed. Frozen layer that is put in the refrigerator after 48 hours, take out the battery, remove one by one parcel out six layers of paper film, lithium batteries have no expansion and deformation caused by frozen surface. After a cooling off period, and then charging.

Low temperature can make internal lithium battery electrolyte change, promote cells react on the frozen. The use of lithium-ion batteries is actually a charge and discharge process. During this period, the battery inside the negatively charged and positive charge/hit each other. The battery will be more and more not after use, because in normal room temperature, the inside of the electronic kinetic energy is larger, so the battery is in active state, relatively frequent leakage situation. And put the lithium battery in low temperature environment, the lithium battery of lithium and electrolyte membrane on the surface of the microstructure, as well as their interface will change significantly, causing the battery internal temporary is not active, to reduce leakage current. So after recharging, cell phones for electricity will increase the time.

3. Make close to scrap lithium battery discharge completely, and then activate the battery recharging the batteries. Specific means is: on the depth of mobile phones for discharge, is through the exhaust internal power, to achieve a deeper level of recharging, the need to adopt some unconventional methods. With a specific device to connect phone with a low voltage small bulbs, inside the battery power will transfer to the small bulbs, until all light. "Mobile phone through low voltage slowly runs out of electricity. Under normal circumstances, if the phone after connect is lower than the rated voltage of 3.6 v, will automatically power off." After put the electric, recharging of mobile phone batteries can be used for a longer time.

To depth discharge of mobile phones, is by running out of internal power, to achieve a deeper level of recharging, the need to adopt some unconventional methods. Find ways to mobile phone connected to a 1.5 V small bulbs, lithium battery internal power will transfer to the small bulbs, until all light." Mobile phone through low voltage slowly run out of electricity. Under normal circumstances, if the phone after connect is lower than the rated voltage of 3.6 v, will automatically power off." After put the electric, recharging of mobile phone batteries can be used for a longer time.
