What is the TC/CC/CV charging method? It is a three-stage charging process for Li-ion cells that ensures the cell is maintained 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:
- TC Phase: cells discharged below 2.9V are 'woken up' with a lower current.
- CC Phase: after reaching 2.9V, the cell is charged with a constant current of 1A (for two cells) or 2A (for one cell).
- CV Phase: 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 charge such a battery to full, it should be placed in the charger before plugging it into the power supply. Charged batteries left in the charger will undergo a natural self-discharge process. Charging will resume when the voltage on the battery drops below 4.1V.
The Xtar PB2C charger has a reactivation function for deeply discharged cells and cells with a voltage of 0V. Many chargers on the market are unable to charge such batteries. Here, the Xtar PB2C charger comes to the rescue, which in many cases allows for the 'rescue' of such cells. Just insert the deeply discharged battery into the PB2C charger, just like with normal charging - the charger will detect the discharged cell and attempt to reactivate it.
Note! Cells discharged below a certain level may suffer irreversible damage, and their reactivation may be impossible. It is advisable to avoid overly deep discharging of Li-ion batteries - this can lead to a significant reduction in their durability and capacity or render them completely inoperative.
Included with the Xtar PB2C charger is a USB Type C cable. The power adapter is not included in the set. To power the charger, any charger with a USB Type C cable, e.g., from a phone, or a USB socket or a computer with a free USB port is sufficient. The recommended minimum power of the charger is 1A (1000mA). It is possible to use a charger with lower power, but in that case, the charging time will be extended.
