!!NEW VERSION!!
Hidden in a compact case is a fully professional processor 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, 17335, 17500, 17670, 18350, 18490, 18500, 18650, 18650, 18700, 20700, 21700, 22650, 25500, 26650
What is the TC/CC/CV charging method? It is a three-stage process for charging Li-ion cells that ensures the cell remains 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 fully charged, the charger switches to charging with a decreasing current until a voltage of 4.2V is reached on the cell. Once 4.2V is reached, 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 top up such a battery to full, it must be placed in the charger before plugging it into the power supply. 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.
The Xtar MC2 charger has the function of reactivating 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. Simply 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 important to avoid excessively deep discharging of Li-ion batteries - this can lead to a significant reduction in their lifespan and capacity or render them completely inoperable.
Included with the charger Xtar MC2 is a micro USB cable and a protective case for the charger during transport. The power adapter is not included in the set. To power the charger, any charger with a micro USB cable, e.g., from a phone, or a USB socket or a computer with a free USB port will suffice. The recommended power of the charger is 1A (1000mA).
