  1. It is normal for the battery temperature to be below 55°C during charging, but due to the high charging current, the battery may heat, so be careful of scalding.
  2. There will be no trickle charging if Li-ion battery is fully charged to prevent overcharging.
  3. There will be trickle charging of 3-5mA of Ni-MH/Ni-Cd battery to ensure it is fully charged.

Battery Discharging

  • After the rechargeable battery is inserted, connect the USB port of the charging device to the port of the charger’s to start discharging. The maximum discharging current is 2A.
  • When discharging, press and hold the button over 2 seconds, the “USB 5V” icon on the LCD display will continue to flash. At this time, the charger unlocks the small current (about 100mA) discharging mode, press the button again over 2 seconds, the “USB 5V” icon is always on and the small current discharging mode is limited.
  • The LCD screen will display the current battery level and voltage during the discharging process.
  • This charger only works with Li-ion battery discharging. When it is charging a battery, the discharging function will be locked. When charging is stopped, the USB discharging function is unlocked and can be used for external devices.

LCD Screen Display

  • The LCD screen will display for 2 seconds after connecting to the power supply. (Pic 1)

  • The battery type, capacity and charging status will be displayed after battery insertion. Single click the button to select charging current during the 8 seconds with the battery symbol displayed. Then single click the button – the screen will cycle through charging current (A)→battery voltage (V)→charging capacity (Ah)→charging time (T). Press and hold the button over 2 seconds to turn off the LCD screen. Single clicking the button again will turn on the LCD screen.

Battery Level Indication

The charger will automatically detect the battery level with battery inserted and connected to the power source. The battery level will be displayed on the LCD screen through battery status bar, and then charging will start. If there is no power connected, the battery level can’t be detected and displayed, even with battery inserted.

Battery level will be displayed as follows by the battery status bar:

One bar constant-on, one flashing, three off: 21% – 40%
Two bars constant-on, one flashing, two off: 41% – 60%
Three bars constant-on, one flashing, one off: 61%- 80%
Four bars constant-on, one flashing: more than 81%
Five bars constant-on: fully charged

    Highly recommended. The charging rate can be reduced which should allow for cooler battery recharging temperature, thus increased longevity.

    Another Fenix winner. This is a professional tool in a compact form. Tons of light and other features. I am a committee member for our local FIREWISE prevention efforts. This flashlight will be given away as a door prize at our upcoming event. The pitch is to have the PD40R V2, charger, and spare battery in your Bug Out kit.
