Frequently Asked Questions (FAQ)
Q1: What batteries does the XTAR FC2 support?
A1: The FC2 supports a wide range of 3.6V/3.7V Li-ion batteries (including 10440, 14500, 18650, 20700, 21700, 26650, etc.) and 1.2V Ni-MH/Ni-CD batteries (AAAA, AAA, AA, A, SC, C).
Q2: How do I change the charging current?
A2: Simply slide the physical switch located on the side of the charger to choose between the three current settings: 0.5A, 1.0A, or 2.0A.
Q3: What do the 4 LED lights indicate?
A3: When the lights are flowing or blinking, the battery is charging or being activated. 4 solid lights mean the battery is fully charged. 4 lights flashing simultaneously indicate that the battery is inserted incorrectly (reverse polarity) or a short circuit has occurred, prompting you to remove it immediately.
Q4: Can I charge a Li-ion and a Ni-MH battery at the same time?
A4: Yes. The FC2 features independent dual-slot circuitry, allowing you to charge a 3.7V Li-ion battery in one slot and a 1.2V Ni-MH battery in the other simultaneously.
Q5: Can the FC2 charge 21700 batteries?
A5: Yes, the FC2 physically supports 21700 battery sizes (without protection boards).
