Four Stages of Lithium Battery Charge

Stage Battery status Description Method
Battery voltage < 3V Recovery state Pre-charge charge with a small current, normally 0.1C
Battery voltage > 3V Can support large current chartge now Constant-Current Charge 0.2-1C
Battery voltage = 4.2V reach battery maximum voltage Constant-Voltage Charge charge current gradually decreases untill 0.01C and end
- End of Charge detect minimum charge rate 0.02C-0.07C (sensor) or two hours later after constant-voltage charge (by timer)
