Hidden in a small case is a fully professional processor charger with a three-stage TC/CC/CV charging process. It charges 1-2 Li-ion 3.6 / 3.7V cells of any capacity in sizes 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700. It is also possible to charge one battery in sizes 20700, 21700 - unprotected only, 25500, 26500.
What is the TC/CC/CV charging method? It is a three-stage charging process for Li-ion cells that ensures that the cell is kept 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 2.85V are 'awakened' with a lower current.
- CC phase: when the cell reaches 2.85V, it 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 cell reaches 4.2V. When 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 as charged by the charger. To fully charge such a battery, insert it into the charger before turning it on. Charged batteries left in the charger will undergo a natural process of self-discharge. Charging will resume when the voltage on the battery drops below 4.1V.
The Xtar MC2 charger has a function to reactivate deeply discharged cells and cells with 0V. Many chargers on the market are unable to charge such batteries. Here with help comes the Xtar MC2 charger, which in many cases allows you to 'rescue' such cells. Simply insert a deeply discharged battery into the MC2 charger, just as you would for normal charging - the charger will detect the discharged cell and attempt to reactivate it.
Note: cells discharged below a certain level are irreversibly damaged and reactivation may not be possible. Avoid discharging Li-ion batteries too deeply - this can lead to a significant reduction in their life and capacity or lead to their complete failure.
