Many people are familiar with the situation when for a year and a half of using a mobile phone, its battery charge is enough for an ever shorter period. This is because the materials used in batteries are designed to last for a certain amount of time.

Instructions

Step 1

There are several ways to recover your phone battery. The most accessible of them is the "treatment" of the battery by increasing the voltage. To do this, connect a voltmeter and the load in parallel with the battery and discharge it to 1 V. At the same time, carefully monitor the voltage, there should not be a drop below 0.9 V. Periodically check the temperature - it should not rise above 50 degrees, if this happens, turn off the load until the battery cools down to room temperature. Further, after discharging to the desired value, wait for the normalization of the processes in the element. This will take approximately 10-15 minutes.

Step 2

Connect the ammeter in series to the phone battery, and the voltmeter and power source in parallel, one contact to the battery pole, the other to the free contact of the installed ammeter. After that, firmly attach the thermal sensor or thermal relay to the battery. For more accurate readings, you can use thermal grease. Set the voltage regulator of the connected power supply to the minimum voltage and start gradually increasing the voltage so that the current on the device reaches the value of a tenth of the full capacity of the battery. For example, for a 1200mA battery, the maximum value would be 120mA.

Step 3

As the current decreases, gradually increase the voltage. First, once every 5 minutes, after an hour - every hour. After reaching the voltage of 1.5 V, stop increasing it and leave the battery charging. After the current drops to almost zero (after about 4-6 hours), disconnect the charging and wait 20-25 minutes until all processes in the battery are normalized. Then fully charge the battery. To achieve good results, this operation must be performed 2-3 times.
