Cell phone battery activation method after out of power

1 Activate with high voltage: use a 12V power supply connect a resistance in series with dozens Ohm. The anode of resistance connects the battery anode, and cathode of the resistance connects battery cathode. Charge it for a while, as long as there is little current, the battery can work. Then you can charge the battery by the charger.

2 if this charge for a few minutes also is bad, will only open the battery directly to recharge the batteries: tear on the label paper, a small mouth until see batteries aluminum frame, in series with the 12 V supply to the resistance the anode input end of the anode on the protection board, the anode to the aluminum shell charge, charge voltage to 3.0 V above can be stopped, at that time lithium battery the protection of the plate protection natural cancel;

3 wrapped in tape bare aluminum shell; Then you can directly use the charger to recharge the battery.

Matters needing attention

Also pay attention to the battery is there any drum, and if so, the battery still can't use; If using the above method or charge it into electricity, then the unwrapped batteries, to the direct recharge the batteries are negative.

or

With a larger power supply, such as about 5 w, 5 v, connect the positive battery cathode, and then take positive, negative electrode touching the battery at the mouth of the disconnect touch can also be a half minutes, stop for a few seconds in touch, more touch a few times you will see the spark, indicates that the battery activation, activation time can't more than ten minutes commonly, if more than can damage cells, or greater than 2 a power supply 5 v output, such as computer power supply 5 v, but the touch time must be no longer than ten seconds, touch for many times, your battery will be coming back to life

In fact, cell phone chargers can be activated. Method is to use across the electrodes of the charger wire leads, and then the positive link battery cathode, anode with anode to touch the power batteries, attention must be quick, I was touched for a long time, (that is three to five seconds), the results of the charger burned, however, is to activate the battery.
