Batteries, unlike batteries, are rechargeable. Lithium-ion batteries are one of the most common types of batteries. Charging methods for these batteries are different from others, so always pay attention to which charger you are using.
It is necessary
- - mobile phone with lithium-ion battery;
- - Charger.
Instructions
Step 1
Completely discharge the battery if you have just purchased a mobile phone. This is best done using Talk Mode. To do this, call any number free of charge for you at the moment when the battery charge level is minimal (the last division of the indicator or sound signals). Wait for the battery level to drop enough for your phone to turn off.
Step 2
Switch on the phone, check the remaining battery charge. If the device turns off again, it means that it is completely discharged. If not, make the call again as in the previous step. Make sure the phone is turned off. Connect it to a charger for a few hours.
Step 3
Wait until the battery is fully charged - you can determine this by the indicator readings on the mobile phone screen. After reaching a full charge, do not disconnect the phone immediately, keep it connected to the charger for a while. Do not interrupt the charging process unless absolutely necessary.
Step 4
Switch on your phone. Perform this "training" several times - this will allow the battery to withstand work for a long time, from two to six days.
Step 5
Use constant voltage method to charge Li-ion batteries. Its essence is to limit the voltage on the battery. The maximum voltage is 4.2 volts, the recommended current is 0.7 C. Reduce the charge current as the voltage on the battery approaches the maximum value. The temperature range when charging is from zero to forty-five degrees Celsius.
Step 6
Make sure the charger is adapted for 4.1 or 4.2 V, the tolerance here is 0.05 V per cell. Please note that a slight rise in temperature (2 to 8 degrees) may occur when the battery is being charged.
