Super fast Charger for 18650 Li-ion cylindrical batteries Xtar OVER 4 SLIM

XTAR OVER 4 SLIM is a professional processor loader with three-stage TC/CC/CV charging PROCESS 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 Xtar OVER 4 SLIM charger 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 OVER 4 SLIM charger has a reactivation function for deep-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 OVER 4 SLIM, which in many cases allows you to ' resave ' such cells. Simply insert a deeply discharged battery into the OVER 4 SLIM 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.
