Cell phone batteries wear out over time. This is directly reflected in his work. It becomes impossible to fully charge the battery, and the charge lasts much less. This problem can be solved in several ways: buy a new battery and try to revive the old one.
Instructions
Step 1
Raise the voltage to reanimate the phone battery. Connect the load and voltmeter to the battery. The connection must be in accordance with the parallel connection diagram. Raise the load to a value not exceeding 1V. Monitor the temperature and voltage of the battery. The temperature should not exceed 50 ° C, and the voltage should not fall below 0.9V. As soon as the temperature reaches the designated point, disconnect the voltage and wait until the battery cools down to room temperature. After discharging to the desired value in the element, the processes should be normalized. This will take about 10-15 minutes.
Step 2
Take an ammeter. You will need it to control the amperage supplied to the battery. Connect it in series. The circuit itself should consist of a parallel connected voltmeter, a power supply and a battery. Install a thermal sensor on the phone battery to monitor the temperature on the cell. Thermal grease can be applied to get the most accurate reading.
Step 3
Set the voltage regulator to the minimum value. Then lift it up smoothly. Monitor the ammeter reading. The amperage should be approximately 1/10 of the battery capacity. Those. if the battery has a capacity of 1200 mA, then the current strength at the current moment should be 120 mA.
Step 4
Increase the voltage as the current decreases. To restore your phone battery. first you need to increase the voltage every 5 minutes. After the hour has passed, increase the tension every hour. After it reaches the 1.5V mark, stop manipulating and put the battery on charge. Wait until the battery is fully charged. It is advisable to perform these operations at least 2-3 times.
Step 5
Check your cell phone battery. If the above steps do not give the desired results, purchase a new battery.
