What is the TC/CC/CV charging method? It is a three-stage charging process for Li-ion cells that ensures the cell is kept in good condition by charging with the appropriate current at each stage and completing the charging process at the right moment.
The individual stages of the TC/CC/CV process are:

• Phase TC: cells discharged below 2.9V are 'woken up' with a lower current.
• Phase CC: after reaching 2.9V, the cell is charged with a constant current of 0.5A.
• Phase CV: when the cell is almost charged, the charger switches to charging with a decreasing current until the voltage of 4.2V is reached on the cell. After reaching 4.2V, the charging process is complete - the battery is fully charged.

Batteries with a voltage of 4.1V or higher are treated by the charger as charged. To recharge such a battery to full, it should be placed in the charger before turning it on. Batteries left in the charger that are charged will undergo a natural self-discharge process. Charging will resume when the voltage on the battery drops below 4.1V.

Chargers from other manufacturers can significantly raise the temperature of the charged cells during charging. Excessive heating of the cells can cause them to wear out faster. In designing the MC1 charger, Xtar has gone a step further than the competition, solving this problem in a simple way: external power supply was used. As a result, the temperature of the battery charged in the MC1 will rise by a maximum of 15 degrees.
