Normal LED Indicator Meanings

  • RED LED indicates an issue.
    • A solid RED LED indicates there is an issue with the battery connection.
    • A flashing RED LED indicates an error (see the troubleshooting below).
  • YELLOW LED indicates the progress of charging.
    • A flashing YELLOW LED indicates the battery is in the Bulk Charging stage.
    • A solid YELLOW LED indicates the battery is in the Absorption Charging stage.
  • GREEN LED indicates the battery is fully charged.
    • A flashing Green LED indicates the battery is fully charged, in Maintenance Mode and is ready to use.
    • A solid Green LED indicates the battery is fully charged, in Long Term Maintenance Mode and is ready to use.

Multi-Stage Charging

Minn Kota’s Multi-Stage Charging delivers a fast, precise charge profile by automatically controlling current and voltage without overcharging your batteries.

  • Bulk: During this stage, the charger delivers full current until the battery reaches ~75% charge. A YELLOW LED is lit to indicate the battery is charging in the Bulk Mode.
  • Absorption: The charging current tapers down while the battery voltage is held at 14.4V (at 77° F). A flashing YELLOW LED indicates the battery is charging in the Absorption Mode.
  • Maintenance: When the battery reaches full charge, the charger voltage is reduced. A flashing GREEN LED is lit to indicate the battery is in Maintenance Mode and ready to use. After 24 hours, the charger automatically turns off and a steady GREEN LED is lit to indicate the battery is in long term Maintenance Mode and ready to use. The charger will automatically resume charging when the battery voltage drops below 12.6V.
  • For more information, you can also refer to the owner's manual (linked below).

Error Conditions

  • Solid Red LED- Check Connections
    1. Check the polarity of the leads to the battery.
    2. Check the connections to the battery and fuses in the output cord.
    3. Check the voltage at the battery. The Portable Charger will not charge a battery that is below 4 volts or above 18 volts.
    4. If still not working, click here to contact us.
  • Flashing Red LED- Temperature Sensor Error
    1. Reset the charger by unplugging the AC Cord. Wait for all LEDs to turn off.
    2. Plug in the AC Cord.
    3. If still not working, click here to contact us.
  • Flashing Red and Green LED- Battery may be damaged
    1. Check to makes sure there are not any loads on the battery.
    2. Check the fluids in the battery and add fluid if necessary.
    3. If the battery voltage does not rise above 10.5 volts in 3 hours or if the absorption voltage does not increase to 14.4 volts (at 77F)), the bank will shut down and will not charger. The battery should be tested.
  • Indicators will not illuminate
    1. Make sure the charger is plugged into an AC outlet.
    2. Check the AC power at the outlet.
    3. Make sure the GFCI (Ground Fault Circuit Interrupter) for the outlet has not tripped.
    4. If an extension cord is being used, check the power at the end of the extension cord.
  • Charger powers up and then turns off
    1. If an extension cord is being used, check the power at the end of the extension cord.
    2. Extension Cord AWG is too small- refer to the chart below for correct AWG.
    3. Very low AC voltage is applied to the charger.
