For boats with on-board chargers.

When storing a boat for a few months do you disconnect the charger ?

Last year I left mine on and the charger bold all of the battery acid out and I had to replace both trolling motor batteries. This year I unplugged the charger think I'd reconnect when the weather start to warm up more.

What is the best approach ? Leave it plugged in or unplug ?

Your charger should not boil them dry. Get a new charger for storage. Battery tenders are for storage.

The bank chargers should be 2 amp maintainers which should be designed to stay hooked up, check the amperage on your chargers.

I can't help with on board charger, I remove mine from the boat, move to garage for winter and put a charge on them about once a month, same for mower/tractor batteries. For my travel trailer I disconnect the batteries and also charge about once a month.

Get yourself a "Guest" brand on board charger and leave it plugged in.
This is the only brand that I have had continued great luck with!
Had others that would boil your battery dry in no time.
I rarely have to add water to my battery and I now get years of service from my batteries.


I'm always in a good mood when I'm fishing.

I use Battery Tender brand for storage.

They are dependable & buy the model that is waterproof.

On my third Guest charger on 2 different boats. They have served me well. Never boiled a battery...always charged and ready.

Well, I run gel cells, which negates to the to run chargers/maintainers...after fishing, I charge my batteries up, then unplug...evening before a fishing trip, I go plug in the charger, and next day I am good to go. The gel cells can be discharged completely (ok to 5%) and will recover just fine, over and over again....long term storage tends not to bother them, at least in my experience. Hope this info helps...

Talk to Dave Goodson at Shut-Up-and-Fish - 972-822-9285

Get yourself a Minnkota Digital on board charger and your battery concerns and troubles will be over. They condition your battery and they won't boil them dry.
Charging rate is all automatic. It goes from quick charge, to optimum, to trickle, and finally maintain. Leave it plugged in all the time, and forget it. Don't forget to unplug it before you go fishing..

I have a sweet 4 bank charger that I'm selling. It will turn off when all the batteries are charged and then just maintain like Battery Tender. It's expensive but i'm selling it.

Any decent on board charger should be able to be to be left plugged in 24/7. After charging the battery it will switch to maintenance mode to keep the batteries topped up. With that being said, I typically plug mine in when I get home and unplug it after a day or so. I then plug it back in the night before I go to the lake just to ensure the batteries are fully topped off. I'm just more comfortable knowing there is no power constantly connected to the boat. Though it may seldom happen, electronics do occasionally fail and having it cause a fire is not out of the question.

Exactly what I do with my batteries.

STRONGLY recommend you guys look at the VDC BatteryMinder. Not just a charger/maintainer, but DESULFATES the battery. Have had several deep cycles last 5 years +.
