Inside the compact casing is a fully professional processor-controlled charger with a three-stage charging process TC/CC/CV. It charges 1-2 Li-ion cells 3.6 / 3.7V of any capacity in sizes 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700. It is also possible to charge one battery of size 20700, 21700 - only unprotected, 25500, 26500.

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 2.85V are 'woken up' with a lower current.
- CC Phase: after reaching 2.85V, the cell is charged with a constant current of 0.5A or 0.25A (depending on the power source used).
- 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 turning it on. 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 MC2 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 MC2 charger comes to the rescue, which in many cases allows for the 'rescue' of such cells. Just insert the deeply discharged battery into the MC2 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 lifespan and capacity or render them completely inoperable.
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 MC2 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 MC2 will rise by a maximum of 15 degrees


Included with the Xtar MC2 charger is a USB-C cable. The power adapter is not included in the set. To power the charger, any charger with a USB-C cable, e.g., from a phone, or a USB socket or a computer with a free USB port is sufficient. The recommended power of the charger is 1A (1000mA).
