Overview
The XTAR FC2 is a highly versatile simple charger with the compatibility of charging Li-ion, Ni-MH, and Ni-Cd batteries. A physical toggle switch allows the user to pick between 0.5, 1, and 2A charging speeds. The FC2 is capable of charging 2 batteries a 0.5A, 2 batteries at 1A, or 1 battery at 2A. Powered by a micro-usb port, max output is dependent on the adapter used.

Frequently Asked Questions
Do 18650 batteries need a special charger?
Yes, they need a lithium ion charger that stops at 4.2V, and the FC2 is one. It uses a TC-CC-CV charging method and cuts off at 4.2V plus or minus 0.05V, so your 18650s fill properly without being overcharged. It also charges NiMH AA and AAA cells, which stop at 1.45V.
What is the voltage of a fully charged 18650 cell?
A fully charged 18650 lithium ion cell sits at about 4.2 volts. That is exactly where the Xtar FC2 stops charging, within 0.05V. The nominal voltage printed on most cells is lower, 3.6 or 3.7V, which is roughly the average the cell runs at as it drains.
How do you bring a dead lithium battery back to life?
If a lithium cell was run down to near zero volts, a charger with a recovery mode can sometimes wake it. The FC2's 0V activation function does that by charging gently until the cell is safe for a normal charge. A cell that is swollen, damaged or won't hold a charge afterward should be recycled.
