Frequently Asked Questions (FAQ)
Q1: Can the Fenix ARE-D2 charge protected 21700 and 26650 batteries?
A1: Yes, the ARE-D2 supports both 21700 and 26650 size batteries. As long as the battery fits physically within the slot, it will charge securely.
Q2: How do I achieve the maximum 2A charging current?
A2: The 2A charging mode is only available when you have a single Li-ion battery inserted in Slot B. If you have batteries in both slots, the maximum current for each slot is 1.0A.
Q3: Can I charge my phone while the ARE-D2 is plugged into a wall outlet?
A3: Yes, the ARE-D2 supports simultaneous input and output. You can charge the batteries via the Micro-USB port while simultaneously using the USB-A port to charge a phone or another USB device.
Q4: What does the LCD screen display during charging?
A4: The LCD screen provides a comprehensive display including a battery frame animation indicating charge status, voltage (V), charging current (A), charged capacity (Ah), and total charging time (T).
Q5: Can I charge LiFePO4 batteries with the ARE-D2?
A5: No, the ARE-D2 is designed specifically for standard 3.6V/3.7V Li-ion and 1.2V Ni-MH batteries. It does not support 3.2V LiFePO4 (Lithium Iron Phosphate) batteries, as it utilizes a fixed charging profile for lithium cells.
