What is the TC/CC/CV charging method? It is a three-stage li-ion cell charging process that ensures that the cell is maintained in good condition by charging with the right current at each stage and completing the charging process at the right time.
The different stages of the TC/CC/CV process are:
•TC phase: cells discharged below 2.9V are 'awakened' by a lower current.
•CC phase: when 2.9V is reached, the cell is charged with a constant current of 1x 2A / 2x 1A / 2x 0.5A (for Ni-MH and Li-ion cells up to 65mm long).
•CV phase: When the cell is almost charged, the charger switches to charging with a decreasing current until the 4.2V voltage on the cell is reached. When the 4.2V is reached, the charging process is complete - the battery is fully charged.

The charged batteries left in the charger will undergo a natural self-discharge process. Charging will resume when the battery voltage drops below 3.9V.
