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

What is the TC / CC / CV charging method? It is a three-stage process of charging Li-ion cells that ensures that the cell is in good condition by charging with the right current at each stage and ending the charging process at the right time.
The individual stages of the TC / CC / CV process are:
• TC phase: cells discharged below 2.9V are "woken up" by a lower current.
• CC phase: after reaching 2.9V, the cell is charged with 2A DC.
• CV phase: when the cell is almost charged, the charger switches to charging with decreasing current until it reaches 4.2V on the cell. After reaching 4.2V, the charging process is completed - the battery is fully charged.

Batteries with a voltage of 4.1V or higher are considered charged by the charger. To fully charge such a battery, insert it into the charger before turning it on. Charged batteries left in the charger will undergo a natural self-discharge process. Charging will resume 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 are not able to charge such batteries. Here, the Xtar SC1 charger comes in handy , which in many cases allows you to 'save' such cells. Just insert a deeply discharged battery into the SC1 charger, as with normal charging - the charger will detect a discharged cell and attempt to reactivate it.

Warning! Cells discharged below a certain level are irreversibly damaged and may not be reactivated. Avoid too deep discharge of Li-ion batteries - this can lead to a significant reduction in their durability and capacity or lead to their total malfunction.

Chargers from other manufacturers can significantly increase the temperature of the cells being charged during charging. Excessive heating of the cells can cause their faster wear. When designing the SC1 charger, Xtar went a step further from the competition, solving this problem in a simple way: power supply from an external power supply was used. As a result, the temperature of the battery charged in SC1 will increase by a maximum of 15 degrees.

Complete with the Xtar SC1 charger, we get a micro USB cable and a protective cover for the charger during transport. The set does not include a power supply. To charge the charger, any charger with a micro USB cable is sufficient, e.g. from a telephone, or a USB socket or a computer with a free USB port. Recommended minimum charger power is 2.1A (2100mA).
