With a digital design and your choice of power levels, our Portable chargers let you bring the action right to your boat. And they feature Automatic Temperature Compensation and fully automatic multi-stage charging to give your batteries the right charge every time you hook up.

Selecting a Charger Location

  • Never place charger above battery being charged; gases from battery will corrode and damage charger.
  • Never allow battery acid to drip on charger when reading electrolyte specific gravity or filling battery.
  • Do not operate charger in a closed-in area or restrict ventilation in any way.
  • Do not set a battery on top of charger.
  • Each DC output cord is six feet long. Make sure that all DC output cords can reach the batteries and that the AC power cord can reach a power source. When using an extension cord, make the AC connection to the charger outside of the battery compartment as far away as practical to reduce the risk of a spark igniting gases in the compartment.
  • Do not shorten the DC output cords, as this can affect charger output. 
  • Even though the Minn Kota charger is capable of operating in a high ambient temperature environment, a minimum of six inches of unobstructed area should be allowed on all sides of the unit for proper air circulation and cooling. Proper cooling and circulation will allow the charger to operate at peak efficiency.

Output Cable Lengths

Each DC output cord is six feet long. Make sure that all DC output cords can reach the batteries and that the AC power cord can reach a power source. Do not shorten the DC output cords, as this can affect charger output.

AC Power Chord Length

The power cord from the charger to the AC power, which plugs into your wall outlet, is six feet long.

Extension Cord AWG for Plugging in the Charger

An extension cord should not be used unless absolutely necessary. Use of improper extension cord could result in a risk of fire and electric shock. If an extension cord must be used, make sure:

  • That pins on plug of extension cord are the same number, size and shape as those of plug on charger.
  • That extension cord is properly wired and in good electrical condition
  • That wire size is large enough for ac ampere rating of charger as specified in table.

Extension cord ratings vary by the Minn Kota Charger model. Please refer to the chart below to find the extension cord that will work best with your model charger.

Charging with a Portable Generator

Careful selection should be used when deciding on a portable generator for electronics. There are 2 important factors that must be considered:

  • Output power:
    • Generators are marketed in output wattage. This wattage must be higher than the power required by the battery charger.
  • Output type:
    • Minn Kota chargers require clean output power from the generator to prevent permanent damage. The generator must replicate the power from a standard AC outlet in your home (clean sine wave output).
  • Safe for use with electrical equipment:
    • The generator must be safe to use with electrical equipment to prevent damage.

Below are the wattage requirements in order to power each charger:

  • 105PD -100W
  • 110PD -165W

Supported Battery Types

  • 12v AGM
  • 12v Flooded Lead Acid

Lithium Batteries

If you would like to use your portable charger with your lithium battery, you will need to contact your battery manufacturer. The Portable Charger has Multi-Stage Charging and provides either 5 or 10 amps for charging the battery. Your battery manufacturer can tell you if the Portable Charger will work to charge your lithium battery.

Multi-Stage Charging

The multi-stage charging has 3 stages, Bulk, Absorption, and Maintenance. The Maintenance stage has 2 modes, Maintenance Mode and Long Term Maintenance Mode.

  • Bulk Mode: During this stage, the charger delivers full current until the battery reaches ~75% charge. The charger will have a solid YELLOW LED to indicate the battery is charging in Bulk Mode.
  • Absorption Mode: The charging current tapers don while the battery voltage is held at 14.4 V (when the air temperature is at 77° F). The charger will have a flashing YELLOW LED to indicate the battery is charging in Absorption Mode.
  • Maintenance Mode: When the battery reaches full charge, the charger voltage is reduced. The charger will have a flashing GREEN LED to indicate the battery is in Maintenance Mode and ready to use.
  • Long Term Maintenance Mode: The charger will turn of automatically after 24 hours of the being in Maintenance Mode. The charger will have a solid GREEN LED to indicate the battery is in Long Term Maintenance Mode and ready to use. While in Long Term Maintenance Mode, the charger will automatically resume charging if the battery charge drops below 12.6 V.

Connecting the Charger to Batteries

Precautions:

  1. Set any switches to Off and unplug the charger before connecting the clips to the battery.
  2. Do not plug the AC cord in until the charger is connected to the battery.
  3. Do not let the clips on the charger touch each other

Determine which post of the battery is grounded.
If the negative post of the battery is grounded:

  1. Connect the Positive (Red) clip from the battery charger to the ungrounded positive battery terminal.
  2. Connect the the Negative (black) clip to the vehicle chassis or a heavy gauge metal part of the frame.
  3. Do not clip to carburetor, fuel lines, or sheet metal body parts.

If the positive post of the battery is grounded:

  1. Connect the the Negative (black) clip from the battery charger to the ungrounded negative battery terminal.
  2. Connect the Positive (Red) clip to the vehicle chassis or a heavy gauge metal part of the frame.
  3. Do not clip to carburetor, fuel lines, or sheet metal body parts.

Connecting the Charger to Power

An extension cord should not be used unless absolutely necessary. Use of an improper extension cord could result in a risk of fire and electrical shock.
If you must use an extension cord, make sure:

  • that the pins on the plug of the extension cord are the same number, size, and shape as those on the plug on the charger.
  • The extension cord is properly wired and in good electrical condition
  • the wire size of the extension cord is large enough for the ac ampere rating of the charger as specified in the table below.

Disconnecting the Charger

Precautions:

  1. Set any switches to Off and unplug the charger before disconnecting the clips from the battery.
  2. Do not let the clips on the charger touch each other.
  1. Turn off the charger.
  2. Disconnect the AC cord.
  3. Remove the clip from the vehicle chassis or a heavy gauge metal part of the frame.
  4. Remove the clip from the battery terminal.

LED Indicators

The LED Indicators on the Portable Charger, lets you know the state of the charger. mceclip6.png

  • Solid RED LED: indicates there is an issue with the battery connection.
  • Flashing RED LED: indicates an error, please see the troubleshooting section of the Owner's Manual.
  • Solid YELLOW LED: indicates Bulk Charging mode.
  • Flashing YELLOW LED: indicates Absorption Charging mode.
  • Flashing GREEN LED: indicates the battery is fully charged, in Maintenance Mode, and is ready to use.
  • Solid GREEN LED: indicates the battery is fully charged, in Long Term Maintenance Mode, and is ready to use.
