The compact casing houses a fully professional processor charger with a three-stage TC / CC / CV charging process. Charges Li / ion 3.6 / 3.7V cells of any capacity in sizes 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700. It is also possible to charge one battery with size 20700, 21700, 22650, 25500 or 26650.
What is the TC / CC / CV charging method? It is a three-stage process of charging Li-ion cells that ensures that the cell is in good condition by charging with the right current at each stage and ending the charging process at the right time.
The individual stages of the TC / CC / CV process are:
• TC phase: cells discharged below 2.9V are "woken up" by a lower current.
• CC phase: 1x 2A / 2x 1A / 2x 0.5A (for Ni-MH and Li-ion cells up to 65mm long)
• CV phase: when the cell is almost charged, the charger switches to charging with decreasing current until it reaches 4.2V on the cell. After reaching 4.2V, the charging process is completed - the battery is fully charged.
Charged batteries left in the charger will undergo a natural self-discharge process. Charging will resume when the battery voltage drops below 3.9V.
The Xtar X2 charger has the function of reactivating deeply discharged and 0V cells. Many chargers on the market are not able to charge such batteries. Here, the Xtar X2 charger comes in handy , which in many cases allows you to 'rescue' such cells. Just insert a deeply discharged battery into the X2 charger, as with normal charging - the charger will detect a discharged cell and attempt to reactivate it.
Warning! Cells discharged below a certain level are irreversibly damaged and may not be reactivated. Avoid too deep discharge of Li-ion batteries - this can lead to a significant reduction in their durability and capacity or lead to their total malfunction.
Chargers from other manufacturers can significantly increase the temperature of the cells being charged during charging. Excessive heating of the cells can cause their faster wear. When designing the X2 charger, Xtar went a step further from the competition by solving this problem in a simple way: power supply from an external power supply was used. As a result, the temperature of the battery charged in X2 will increase by a maximum of 15 degrees.
Together with the Xtar X2 charger we get a 2-pin network cable (so-called eight). The set does not include a USB power supply. To power the charger, any charger with a USB socket is sufficient, e.g. from a telephone, or a USB socket or a computer with a free USB port. Recommended charger power is 2.1A (2100mA).
