VC2 is a professional processor loader with three-stage charging process TC/CC/CV and LCD display. It charges 1-2 Li-ion 3.6/3.7 V cells with any capacity in sizes 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700, 20700, 21700, 22650, 25500, 26650.

The illuminated LCD display of the charger Xtar VC2 shows up to date the status of the charger: the voltage of the batteries charged, the charging current, the load used to charge the cells, indicates. Errors and informs you that the charging is complete. Information on the load used can be used to measure the capacity of the batteries. To measure the capacity of the battery, it must be discharged to the appropriate voltage cut-off level (usually 2, 5V) and inserted into the charger VC2. When charging is complete, you can read the value of the charge used to charge the battery. This will Always be a value of 3-5% higher than the actual battery capacity. Due to the fact that the charging process of batteries is never in 100% efficient, ie. A slightly larger load is needed to charge the battery than the actual cell capacity is.

What Is THE TC/CC/CV charging method? It is a three-step process of loading Li-ion cells to keep the cell in good condition by charging the right current at each stage and completing the charging process at the right moment.
The various stages of the TC/CC/CV process are:
• TC phase: Cells discharged below 2, 9V are ' awake ' to lower currents.
• CC phase: When 2, 9V is reached, the cell is loaded with a constant current of 0, 05A to 0, 5A (depending on the power source being used).
• CV phase: When the cell is already nearly charged, the charger switches to a decreasing current charge until it reaches a voltage of 4, 2V on the cell. After reaching 4, 2V the charging process is complete-the battery is fully charged.

When left in the charger, the charged batteries will be subjected to a natural self-discharge process. Charging will resume when the battery voltage drops below 3.9 v.

The Xtar VC2 Charger has a function of reactivating deeply discharged cells and cells with a Voltage Of 0v. Many chargers on the market are not able to charge such batteries. Here with the help comes the charger Xtar VC2, which in many cases allows you to ' resave ' such cells. Just insert a deeply discharged battery into the VC2 charger, as with normal charging, the charger detects the unloaded link and attempts to reactivate it. Attention! Cells unloaded below a certain level are irreversible and reactivated may not be possible. Avoid too deep discharge of Li-ion batteries-this can lead to a significant reduction in their durability and capacity or

Their total disability.

Supplied with the Xtar VC2 charger, we get a micro USB cable and a cover for securing the charger for transport. The power supply is not Included In the set. Any charger with a micro USB cable, for example, is enough to power the charger. Phone, or USB port or a computer with a free USB socket. The recommended charger power is 2A (2000mA).
