Three definitive approaches of lithium battery repair

Common three methods of mobile phone lithium battery repair:

1, use a clean eraser or other material lithium wiped gently cleaning tools battery on the metal on metal contact and phone contact, help charging condition and lasting power.

2, will use automatic shutdown old cell phones lithium battery firmly wrapped with plastic wrap, break, as far as possible when the parcel inside and a total of three layers, make sure that 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.

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 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.

Cell phone lithium battery repair - process analysis of "frozen therapy" :

In April 2009 to buy original lithium battery as the subjects.The lithium batteries have been used for nearly two years, under the condition of normal use, the phone standby time to maintain a day or so.If the phone number is more, the duration of the battery will be more short.If the average talk time of each call for 3 minutes, to answer or dial 10 times, power is in jeopardy.

Before the test, turn off your phone, after the battery is full of it.Since then, no answer and the phone call any phone, also do not send and receive messages.Without any interference, that mobile phone standby quietly, after nearly three days no electricity.

Entered the stage of experiment, the whole body equipped with a good cell phone lithium battery in the fridge frozen lattice (to prevent the lithium battery be affected with damp be affected with damp, need to phone firmly wrapped with plastic wrap, first break, as far as possible when the parcel inside and a total of three layers, to ensure that the lithium battery in the vacuum state.Outside the plastic wrap, then bread three layers of newspaper, cell phone battery completely sealed).After 48 hours, remove the lithium battery, remove the parcel out one by one of the six layers of paper film, batteries without expansion and deformation caused by frozen surface.After a cooling off period, the lithium battery load with a mobile phone and boot.The same case, the third days would have automatic shutdown of the mobile phone, the screen only a less electricity.After a week, still remaining on the phone's screen grid electricity.The ninth day, mobile phone to prompt because of electricity shortage.

"Frozen therapy" performance before and after the test confirmed the point: for the first time after freezing can prolong the stay of mobile phone battery time.But freezing is not "undead elixir" of mobile phone batteries, use for a long time will damage the lithium battery.

Note:

About 600 times the cycle of lithium battery service life.If you charge more, hot games make its internal molecules arranged microstructure gradually destroyed, storage charge efficiency will decrease gradually.And "freezing process is easy to damage the internal structure of the original battery, a short period of time may increase the ability to take charge, but long-term use may not be effective."Leaf, says prof lithium battery inside the microstructure once destroyed, it is impossible to completely recover again, long-term use of this method will accelerate cell phone battery consumption.

Experts remind lithium battery is not too high, the price of their effort in lithium battery repair, than to buy a new battery more convenient and cost-effective.In addition, develop good habits, is also a shortcut to extend the service life of lithium-ion batteries.
