Xtar FC2 Compact, Fast Processor Charger
for Li-ion and Ni-MH batteries in sizes 18650 and other

Xtar is a renowned manufacturer of high quality Li-ion chargers, flashlights and Li-ion batteries. Xtar products are sold in more than 120 countries, including min. Germany, Japan and Russia. Xtar uses the highest quality materials for the production of chargers , from plastic housing to efficient electronics. All Xtar chargers are CE certified in European markets.

A fully professional processor charger with a three-stage TC/CC/CVcharging process is hidden in a small case. It charges 3.6/ 3.7V Li-ion cells of any capacity in sizes 18650, 18700, 20700, 21700, 22650, 25500, 26650. It also charges Ni-MH 1.2V batteries in sizes AAAA, AAA, AA, SC and C.

remark!!
THE FC2 CHARGER ALSO SUPPORTS 20700 AND 21700 PROTECTED BATTERIES.

What is the TC/CC/CV charging method? It is a three-stage li-ion cell charging process that ensures that the cell is maintained in good condition by charging with 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 'awakened' by a lower current.
• CC phase: when reached 2.9V, the cell is charged with a constant current of 2x2A / 1x3A.
• CV phase: When the cell is almost charged, the charger switches to charging with a decreasing current until the 4.2V voltage on the cell is reached. When the 4.2V is reached, the charging process is complete - the battery is fully charged.

Batteries with a voltage of 4.1V or higher are considered charged by the charger. To fully recharge the battery, insert it into the charger before turning it on. The 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 FC2 charger has the function of reactivating deep discharge cells and 0V cells. Many chargers on the market are unable to charge such batteries. Here comes the Xtar FC2 charger,which in many cases allows you to 'rescue' such cells. Simply insert a deeply discharged battery into the FC2 charger, as with a normal charge - the charger will detect the discharged cell and attempt to reactivate it.

Attention! Cells discharged below a certain level are irreparably damaged and may not be able to be reactivated. Avoid draining li-ion batteries too deeply - this can significantly reduce their durability and capacity or lead to their complete malfunction.

Chargers from other manufacturers can significantly increase the temperature of charged cells during charging. Overheating of cells can cause them to wear out more quickly. When designing the FC2 charger, Xtar went a step further than the competition, solving this problem in a simple way: power from an external power supply was used. This will increase the temperature of the rechargeable battery charged in FC2 by up to 15 degrees.

Complete with Xtar FC2 charger we get a micro USB cable. No power supply is included. Any charger with a micro USB cable, such as a phone or USB port, or a computer with a free USB port, is all you need to power the charger. The recommended minimum charger power is 2A).
