How to repair the phone's battery

The battery of a mobile phone is graduallywears out, which negatively affects its work. Charge the battery to the end becomes more difficult, and the charge is kept very little time. Of course, you can buy a new battery, but you can try and reanimate the old one.

How to repair the phone's battery

You will need

  • - the voltmeter;
  • - ammeter;
  • - Thermal sensor;
  • - Thermal grease.

Instructions

1

Raise the voltage to reanimate the batteryphone. Connect the voltmeter and the load to the battery using the parallel connection scheme. Carefully lift the load, make sure that it does not exceed 1V.

2

Watch for voltage and temperaturebattery. The voltage should not fall below 0.9V, and the temperature should not be raised above 50 ° C. As it reaches this point, turn off the power and cool the battery to room temperature. Such a discharge should help in the normalization of processes inside the battery. The time it takes is no more than 10-15 minutes.

3

Use an ammeter to controlincoming to the battery of amperage. Connect it in series by connecting the voltmeter, the power source and the battery in parallel. Install the temperature sensor on the battery to monitor the temperature on the element. Apply thermal paste to get accurate readings.

4

Set the minimum value on the regulatorvoltage. Start smoothly lifting it, not forgetting to monitor the ammeter readings. The current should not exceed 1/10 of the capacity of the battery. So, for a battery with a capacity of 1200 mA, the current must be equal to 120 mA.

5

Increase the voltage as the current falls. To restore the phone's battery, increase the voltage enough time in 5 minutes. Every hour, gradually build up the tension. Once it reaches 1.5V, stop at this and put the battery to charge. It is better to do this by waiting for the battery to completely empty. It is desirable to produce these operations at least 2-3 times.

6

Check the reconditioned mobile phone battery. If, as a result of the actions described above, you did not get the desired results, it is better to purchase a new battery.
