VC4S is a professional processor loader with three-stage charging process TC/CC/CV and LCD display. It charges 1-4 Li-ion 3.6/3, 7V and Ni-MH cells with any capacity in the sizes AAA/R03, AA/R6, R14/C, 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700, 20700, 21700, 22650, 25500, 26650.

Illuminated VA LCD Charger display Xtar VC4S shows up to date information on the operating status of the charger: rechargeable batteries Expressed in mAh, battery voltage, charging current and internal resistance of the cell.

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 1A to 3A (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 VC4S 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 VC4S, which in many cases allows you to ' resave ' such cells. Just insert a deeply discharged battery into the VC4S 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 to their total malfunction.

Supplied with the Xtar VC4S charger, we get a micro USB cable and a pouch to help you transport the charger. The power supply is not Included In the set. To power the charger, you only need any charger with a USB port, (the recommended charger is compatible with the QC 3.0 standard).
