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) |
