When the beloved cell phone began to frequent power outages, you do not have insisted on a change to re-new battery, recently, the widely circulated that there Gaoren invention of the magic way to make mobile phone batteries and "revived", two of which are widely spread approach is to the battery in the refrigerator "frozen" and the use of rubber friction. However, these methods Emmanuel really do? Reporter specially invited Weikai detection of Guangzhou Institute of Technology Laboratory of experts for the Dell Inspiron 1100 Laptop Battery.

Identification 1: Frozen France

"Folk secret":

1, the battery pack with newspaper before being placed in plastic bags, wrapping up well into the freezer for three days, newspapers can absorb excess moisture;

2, three days after the decentralization of two days out at room temperature;

3, two days after the battery charge, charge, yellow cell phone saturation test is estimated to save 80% ~ 90%.

Experts say:

This report was groundless. General cell phone lithium-ion batteries in use in 2012, after the charge and discharge hundreds of times basic internal activity has been reduced chemical substances not normally a high efficiency charging and discharging.

As an argument is a simple temperature cycle test, the internal chemical substance can not be fully activated, the correct approach is to a professional recycling companies, decomposition to extract useful substances to prepare a new battery.

IB 2: rubber friction piece brass contact method

"Folk secret":

Remove the battery after the battery with an eraser on the contact (brass piece) wipe clean, and then loaded back to the phone, the battery will be able to magic them back to life, but also as the new stars.

Experts say:

This approach can only be effective for some batteries. For certain lithium-ion battery is effective because the built-in shield reasons. Lithium-ion batteries are generally built-in protection board, limit its voltage range in a certain charge and discharge, when the voltage is abnormal (too high or too low), the action is triggered to cut off the power shield, rubber friction and the charging process which may promote the protection of board to recover, so the Acer Travelmate 4000 Laptop Battery can work properly. In addition, the terminal does not rule out sometimes caused by bad contact above the dirt, when properly clean and maintain good conductive contact with the normal.

Experts also warned that the current failure of individual cottage battery protection board can not be reset, or terminal contact conductive material difference in itself bad, or batteries quality problems, no matter how it is useless to use an eraser.
