Xtar is a renowned manufacturer of high-quality Li-ion battery chargers, flashlights and Li-ion batteries. Xtar products are sold in over 120 countries, including the USA, Germany, Japan and Russia. Xtar uses the highest quality materials for its chargers, from the housing plastic to efficient electronics.

In a small housing there is a fully professional processor charger with a three-stage TC/CC/CV charging process. It charges 3.6 / 3.7V Li-ion cells of any capacity in sizes 10440, 14500, 14650, 16340, 17500, 17670, 18350, 18500, 18650, 18700, 20700, 21700 - only unprotected.

What is the TC/CC/CV charging method? It is a three-stage Li-ion cell charging process that keeps the cell in good condition by charging with appropriate current at each stage and ending the charging process at the right moment.

• TC phase: cells discharged below 2.9V are 'woken up' with lower current.
• CC phase: after reaching 2.9V, the cell is charged with constant current 0.5A (batteries up to 54mm long) or 1A (batteries over 54mm long).
• CV phase: when the cell is almost charged, the charger switches to charging with decreasing current until reaching 4.2V on the cell. After reaching 4.2V, the charging process is complete - the battery is fully charged.

Batteries with voltage 4.1V or higher are treated by the charger as charged. To top up such a battery to full, insert it into the charger before connecting the charger to power. Fully charged batteries left in the charger will undergo natural self-discharge. Charging will resume when the battery voltage drops below 4.1V.

The Xtar MC2 Plus charger has a reactivation function for deeply discharged cells and cells with 0V. Many chargers on the market cannot charge such batteries. The Xtar MC2 charger comes to the rescue, which in many cases allows 'reviving' such cells. Simply insert a deeply discharged battery into the MC2 charger as for normal charging - the charger will detect the discharged cell and attempt to reactivate it. Note! Cells discharged below a certain level are irreversibly damaged and their reactivation may be impossible. Avoid excessive discharge of Li-ion batteries - it can significantly reduce their durability and capacity or lead to complete failure.

Chargers from other manufacturers can significantly increase the temperature of charged cells during charging. Excessive heating of cells can cause faster wear. When designing the MC2 Plus charger, Xtar went a step further than the competition, solving this problem in a simple way: power is supplied from an external power supply. Thanks to this, the temperature of the battery charged in MC2 Plus will increase by at most 15 degrees.

• Included with the Xtar MC2 Plus charger: micro USB cable and a protective pouch for transport. No power supply is included. To power the charger, any charger with a micro USB cable, e.g. from a phone, or a USB port or computer with a free USB port is sufficient. Recommended USB power supply power is 2A (2000mA). It is possible to use a 1A charger, but then the charging time will be longer.
