Junk Charger

I have a 2019 ranger. This is the 2nd MK3150 charger I have had on the boat. The service rep told me that minn kota products just go haywire when used for 3 or more years. Would not replace the charger. The 3 lights are flashing in a sequance not listed in the manual. Tech lady told me it was the 3 new batteries i purchased this morning. All three were supposed to all be bad.So this will be the last Minnkota product that I ever own.

Works As It Should

My 1st one lasted 7 yrs went out on a lightning strike was always dependable kept my batteries warm and fully charged in the winter I bought the same one because of this

Works Great For About 4 Years

unit works great for about four years. Then I lost one bank. This is the second time it's happened.

Mk 315 D 3 Bank X 5 Amps

The only hard part of installation was finding the space. All the rest was just following the instructions. It's working great!

The Worst!

Maybe three years old, and some how it’s full of water. It rusted from the inside out. Definitely Not waterproof. My boat didn’t sink so must have been the humidity in that boat compartment.

Easy Install. Great Charger

This is my second Minn kota charger they have been flawless

One Bank Goes Out

I’m having to replace due to the bottom bank going out. Found out this is a known issue. Since I don’t want to modify things in a tight space I will go back and take my chances but would otherwise go with a different product.

Replace An Onboard 3 Bank Failed Ruined Starting B

Bought today installed in 20 minutes , all 3 batteries already charged ready to fish SO easy to install plugin walk away unplug when in he green Very glad I purchased nice warranty as well

Customer Service

I purchased a MK 315D 3 bank charger over a month ago. On June 10th I contacted Minn Kota about one of the banks not working. The gentleman I spoke with explained that a new one would be sent out shortly. I received the new one yesterday and installed it right away. It is working as it is designed. My complete satisfaction with Minn Kota is over 5 stars. Thanks to all for getting me back on the water quicker than I expected. Randy

Great Charger

This is my third minnkota charger a excellent charger

Replaced A Mk210d

I replaced my mk210 that I had used for 9 years without an issue.

Worry Free Charging!

Purchased the MK 315D 3-bank charger when I purchased my Terrova trolling motor. It’s nice the plugging the boat in at the end of the day and knowing in the morning all the batteries are fresh and ready to go including my cranking battery. Also installed the AC Power port MKR-21 to make charging that much more convenient!

Good Charger

Replaced old onboard charger first of 2017 Has never failed since and keeps my 2x 12v trolling batteries and 12v cranking battery charged as should. Recharges to max overnight and my 2x 12v (24v) are over 5 years old now. Good buy for the money.
