A fully professional processor charger with a three-stage TC / CC / CV charging process is hidden in a small case. Charges 3.6 / 3.7V Li-ion cells of any capacity in sizes 18650, 18700, 20700, 21700, 22650, 25500, 26650.

What is TC / CC / CV charging method? It is a three-stage Li-ion cell charging process that keeps the cell in good condition by charging the right current at each stage and completing the charging process at the right time.
The different stages of the TC / CC / CV process are:
• TC phase: Cells discharged below 2.9V are "awake" for lower current.
• CC phase: When we reach 2.9V, the cell is loaded with a constant current of 2A.
• CV phase: When the cell is almost full, the charger switches to decreasing current until it reaches a voltage of 4.2V on the cell. After charging to 4.2V, the charging process is complete - the battery is fully charged.

Batteries with a voltage of 4.1 V or more are treated by the charger as charged. To charge such a full battery, insert it into the charger before turning it on. When left in the charger, charged batteries will undergo a natural self-discharge process. Charging will continue when the battery voltage drops below 4.1V.

The Xtar SC1 charger has the function of reactivating deeply discharged and 0v cells. Many chargers on the market cannot charge such batteries. Help here
the Xtar SC1 charger, which in many cases allows such cells to be 'restored'. Simply insert a deeply discharged battery into the SC1 charger, as during normal charging the charger detects an unloaded connection and attempts to reactivate it. Attention! Cells depleted below a certain level are irreversible and may not be reactivated. Avoid overdischarging Li-ion batteries - this can lead to a significant reduction in their durability and performance or to complete failure.

Chargers from other manufacturers can significantly increase the temperature of the charged cells during charging. Cells can wear out faster due to excessive heating. When designing the SC1 charger, Xtar went a step further than the competition and solved this problem easily: an external power supply was used. This ensures that the charging temperature in the SC1 battery rises to 15 degrees.

The Xtar SC1 charger comes with a micro USB cable and a case. The power supply is not included in the set. For example, any charger with a micro USB cable is enough to power the charger. A phone, a USB port or a computer with a free USB socket. The recommended minimum power of the charger is 0.5 A (500 mA).
