Pontoon Boat & Deck Boat Forum

I have white stuff on my charger appears like the same stuff you might get on a battery post...it is a Minn Kota 2 bank for a 24v ... how would I clean it and what makes it get this way.?

I have never seen that but my first thought is salt. You boat in saltwater?

My second thought would be that you're getting some deposits from the degassing of your batteries as they charge. I know those batteries can expulse hydrogen gas among other things. If you are charging multiple batteries in tight quarters with no venting, it doesn't seem out of the realm of possibility that you would see some residue on your charger.

Can you post a pic or two of it?
I also have a MinnKota two bank charger.

I was wondering where the corrosion or oxidation is forming.

Joe , right on top of the charger.

Here is what I would do if I were you.

1) Check the fluid in your batteries. Make sure your charger isn't "boiling" your batteries.

2) Clean your charger off and go a week or two where you charge with your battery hatch open to allow ventilation to see if that white stuff comes back.

Also, do you see any of the residue on the other surfaces in your battery compartment?

I can't add water they are sealed gel
