FENIX ARE-D2 product features:

Charging current:

• Channel A is for normal charging and channel B is for fast charging, the rated charging current of both channels is 1.0A.
• Li-ion battery – when channels A&B or only channel A are installed with batteries: 0.5A and 1.0A can be selected by clicking the corresponding button once; when only channel B is installed with batteries: 0.5A, 1.0A and 2.0A can be selected by clicking the B button once.
• Ni-MH / Ni-Cd batteries – 0.5A and 1.0A can be selected for channel A or B by pressing the corresponding button once.

Battery discharge

• Channel B is in discharge state then channel A has no battery installed.
• After rechargeable battery inserted into channel B, connect the USB port of the charging device to the port of the charger to start discharging. The maximum discharge current is 2A.
• When discharging, press and hold the button for more than 2 seconds, the “USB 5V” icon on the LCD screen will continue to flash. At this time, the charger opens the small current discharge mode (about 100mA), press the button again for 2 seconds, the “USB 5V” icon is always on, and the small current discharge mode is limited.
• The LCD display will show the battery level and current voltage during discharge.
  *This charger only works when discharging Li-ion battery. When it is charging, the discharging function will be locked. When charging is stopped, the USB discharging function will be unlocked and can be used for external devices.

Note:

• Battery temperature below 55°C during charging is normal, but due to high charging current, the battery may get hot
• Trickle charge 3-5mA for Ni-MH/Ni-Cd battery to ensure battery is fully charged.

LCD screen

• The LCD screen will display light for 2 seconds after connecting to power source.
• If the channel has no battery, the LCD screen will only show the battery symbol after 2 seconds, and the screen will turn off after 30 seconds. Press any button once, the screen will light up with the battery symbol displayed.
• The battery type, capacity and charging status will be displayed after installing the battery. Click the corresponding button once to select the charging current for 8 seconds with the battery icon displayed. Then click the button once – the display will cycle through charging current (mA) → battery voltage (V) → charging capacity (mAh) → charging time (T). Press and hold the button for 2 seconds to turn off the LCD display. Press the button again to turn on the LCD display.

The battery LED displays as follows on the battery status bar

• 1 flashing light: battery is less than 20%
• 2 flashing lights, battery level: 21% – 40%
• 3 flashing lights, battery level: 41% – 60%
• 4 flashing lights, battery level: 61% – 80%
• 5 flashing lights, battery about: more than 81%
• The light does not flash, is steady on: the battery is fully charged.

Short circuit protection feature

• If a short circuit is detected, charging will automatically run.

Reverse voltage protection

• If the battery is installed incorrectly, charging will not start.

Overload protection

• When fully charged, the charging current on the LCD screen will display 0.
