Lithium battery charging notes 1. Standard charging method: use 0.2C5 constant current to charge the battery terminal voltage to 4.20V, change to constant voltage charging, until the charging current u003c0.01C5 is regarded as overflow; standard charging method is often used for battery capacity Calibration, because the charging is too slow, it is rarely used in daily use. 2. Fast charging method: charge with 1C5 constant current until the battery terminal voltage is 4.20V, change to constant current charging, until the charging current is u003c0.01C5; lithium battery.jpg The precautions of lithium battery fast charging method ①The initial charging current should not be too high If the battery terminal voltage reaches 4.20V, it must be switched to constant voltage immediately. The voltage requirement is relatively high (error u003c0.5%), and it must be measured with a four-and-a-half-digit multimeter. 3. Charge according to the standard time and procedure, even if it is the first three times, plug the charger into the power supply first, and then plug the output end of the charger into the charging port of the mobile phone; 4. When the mobile phone battery is too low prompt appears , You should start charging as soon as possible; the lithium battery is most easily damaged in the case of over-discharge; 5. There is no special way to activate the lithium battery. The lithium battery will be naturally activated during the normal use of the mobile phone.
