'Like' or Google+ this item.

Hit the water with the confidence of a consistently, reliably charged battery! Minn Kota® Onboard Chargers are available with varying levels of banks and amps so you can find the perfect fit for your trolling set-up. Each model features automatic temperature compensation and multi-stage charging to ensure a proper charge every time. See below for more on selecting the right Charger for your set-up!

Digitally Controlled

Minn Kota set out to build a smarter charger, and the result is the ingenious microprocessor-based design of this on-board unit. By monitoring factors like temperature and state of charge, it delivers a faster, more regulated precise charge. You stay out on the water longer, without worrying about your batteries.

Protects Batteries

Multi-stage charging and automatic temperature compensation for more precise charges that won't damage your battery. Automatic shut-off extends battery life by shutting down when charging is complete.

Two Times Faster Charging

In high temps, the MKD Series Onboard Charger juices up your batteries up to twice as fast! Thanks to a digital design that monitors everything from temperature to state of charge, you get a quick, efficient, "smart" charge!

Enhanced Status Codes

Comprehensive readings on your Charger inform you of the charge stage, maintenance mode status, error notifications and full charge. No guessing games necessary.

More Charger details:

  • Waterproof, shock, and vibration-resistant construction
  • For use with 12-volt / 6-cell batteries (with 50-130 amp hour rating) that are flooded / wet cell, maintenance free, or starved electrolyte (AGM) only
  • Saltwater-tested and completely corrosion-resistant
  • Short circuit, reverse polarity and ignition protected
  • UL listed to 1236 marine standards. FCC compliant. Requires 120-volt power for recharge.

Choosing yours is an easy 3-step process:

Step 1 - Determine how many banks your trolling system requires... 24-volt systems need 2 banks, 36-volt systems need 3 banks, and 48-volt systems need 4 banks.

Step 2 - Determine the speed of recharge you want. For 3-5 hours recharge time, you'll want 15 amps per bank. For 4-6 hours recharge, you'll want 10 amps per bank.

Step 3 - Select the Charger that best meets your needs from the chart below.
