Frequently Asked Questions (FAQ)
Q1: What is included in this bundle?
A1: The bundle includes one XTAR SC2 smart charger, one Type-C charging cable, one user manual, and either 1 or 2 units of the XTAR 18650 3500mAh 10A protected button-top batteries based on your selected variant.
Q2: How do I achieve the 3A fast charging speed?
A2: To reach 3A fast charging, use a single battery in one slot and ensure your power adapter supports QC3.0 (9V/2A or 12V/1.5A). The SC2 will automatically detect the input power and output a 3A current.
Q3: What do the LED lights indicate?
A3: Flashing lights indicate the charging current (1/2/3 LEDs for 1/2/3A) or that the battery is actively charging; 4 solid lights mean the battery is fully charged; 4 flashing lights at the same time indicate the battery is inserted incorrectly (reverse polarity protection activated).
Q4: Is the SC2 safe to charge this 18650 battery overnight?
A4: Absolutely. The SC2 features a precise 4.20V charging cut-off. Once the battery reaches full voltage, the charger automatically stops, preventing overcharging and ensuring long-term battery health.
Q5: Can I charge other types of batteries with this charger?
A5: Yes. The SC2 is highly versatile and supports 3.6V/3.7V Li-ion batteries in various sizes, including 18650, 18700, 20700, 21700, 22650, and 26650 (it supports protected 20700 and 21700 cells as well).
