Minnkota charger not charging

[MNBIGBEAR]

I have a minnkota onboard charger. I plug it in and it says that my battery is at full charge when I know it definitely is not. Any suggestions?

Call Minnkota. Otherwise, return it.

[fish2live]

are you running a 12 or 24 volt system

[MNBIGBEAR]

12 volt. Ive only had it for about 2 months and it has worked great up until now. Thanks again guys.

You may want to have your batteries tested, the charger will not charge a bad battery.

I just had the same problem with my Minkota charger. Another thing is make sure any trolling motor charger you get is at least 10 amp. I had a 6 and was told it wont fully charge a trolling motor battery. I went and got a new 20 amp 2 bank. 10 amps to each bank. I just got it so I will let ya know how it goes once I use it a few times.

Why wouldn't a 6 amp charge your trolling motor battery? Did they give you an explanation? I don't know a lot about the working of chargers/batteries when it comes to the technical stuff. But that doesn't make a lot of sense to me. I have a 3 bank, 23 amp charger. 10 to each of the deep cycles and 3 to the starter. Wouldn't this also mean that a 3 wouldn't charge my starter completely? I realize that my starter rarely needs a charge. But I'd be interested to know the reasoning why a 6 amp bank may not charge a deep cycle completely.

That's not true. It's true that it would take longer. But there isn't a magic number with will or won't charge your battery. You could charge it with a 1 amp charger if you had the time...

I didnt ask for a explanation sense they were willing to give me store credit towards a new unit. Ill talk to the guy and ask why he told me that.

I have the same problem with my minnkota onboard charger 6 amp. I plug it in and it says charged or charges for 5 min. then says charged. I've gone threw 2 regular minnkota chargers and now this one in the last 5 years. Can someone suggest a charger that works

I've had a Guest charger for the last 5 years and have also had the same set of batteries. No problems at all, the batteries are from Batteries Plus. I just make sure that I get the system plugged in after EVERY time I use the boat.

Speaking of Guest chargers -- I was surprised to see a 2-bank 4A/4A on-board charger at Gander for $30. They also had a 1 bank 4A for $20. 4A isn't a quick charge, but gets the job done in 24 hrs. A cheap charger... but your Minnkota's don't seem to be living up to their expectations...

I am having the same problem currently. My charger reads that my batteries are done, but I know they have no juice. I installed new batteries last year and those are pretty much dead now. Am I able to leave the charger plugged into my extension cord for several days? or will this fry my batteries. I run a 24 volt system. I am scared to go out and buy two new ones not knowing if my charger is not working correctly. I appreciate any and all feedback. The charger is 5 years old by the way. One last question, If my male end of the charger has three prongs, but my female end only has two, can I only plug in the two and get an o.k charge from that? Sorry for all the questions, I am not the most knowledgable when it comes to these things. Thanks

I run Dual Pro in my boat. Talk about support!!! I had one go bad a couple years ago and called them. They shipped one out UPS that day with a return slip to send the old one back without charge to me. This unit was two years old and one of the three banks quit working. They replaced it with NO questions and NO cost to me what so ever!!! Only had to put the clip on charger on the boat twice before the new one got there. This, right in the heart of my guiding season. Thanks Dual Pro!!!!

I have seen numerous posts on here and on another board about onboard charger problems. I am in the market for a new 90 hp tiller boat and my question is. Is there alot of problems associated with onboard chargers? Is there a better brand to go with? Thanks for any info you can shed on this.
