XTAR ST2 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 of any capacity in sizes 18650, 18700, 20700, 21700, 22650, 25500, 26650.
The illuminated LCD display of the charger Xtar ST2 shows the battery charge status in a percentage.
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 indicated by the user.
• 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.
The Xtar ST2 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 ST2, which in many cases allows you to ' resave ' such cells. Just insert a deeply discharged battery into the ST2 charger, as with normal charging, the charger detects the unloaded link and attempts to reactivate it.
Note! Cells unloaded below a certain level
Irreversible damage and reactivation 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.
