Battery Corrosion
So I've been having corrosion return after cleaning pretty quick. Alt is putting out normal and batteries are holding up. The issue is the divers side positive is getting corrosion and the passenger side negative is getting corrosion. I am going to be replacing the positive cable (have on hand) and now will be getting a negative one for the passenger side. My question is--without replacing the whole system-cables, batteries, and alt--what is my issue causing the corrosion? Or what direction do I need to look in.

Go to Napa and get a can of Noco NCP-2 battery corrosion protectant. Clean the cables real good and then spray the connections with the Noco. Best stuff I have found for this
purpose. Had the same problem on my 05 and this stuff stopped it dead. I'm now using it on my 2015.

I doubt I would be able to find it. Wouldn't know where to even start looking/testing.Go to Napa and get a can of Noco NCP-2 battery corrosion protectant. Clean the cables real good and then spray the connections with the Noco. Best stuff I have found for this

That's kinda what I was hoping--kinda. So with battery getting weak--the alt will overcharge trying to get the battery to where it needs to be?

Thats what I was getting at even a small draw is still a draw lowers the battery eventually. You seldom notice it unless it is several days without being restarted.
If you start it will cause the alt to recharge the battery more than normal to keep the battery up because part of its charge is being drawn off. It never really reaches full charge.

That's the thing--I did that a few months back--then it came back, did it again and the driver side pos. has not been as bad but the pass. side neg. keeps coming back with force (worse than before)

Take the cable end and put it in a coke, it will foam at first and then dig in cleaning. Leave it about 8 hours and rinse with water, then apply whatever to the connection and battery post. We used in in the Navy to clean brass and copper, it will eat anything on the copper up inside the wire cover you can't get to.

The lead chunk sticking up out of the battery, it's connected to the lead plates in the battery. If the seal breaks between terminal/post/lead chunk and the case, acid will leak out. If it's leaking, putting baking soda on it is not going to do your battery any favors.

Not worried about the batteries now--decided I'll just change them out. Will buy some coke to soak the passenger side negative terminal in, put the new positive cable on, and dress the new batteries with the red stuff. Was wanting to wait a little lo ger but the corrosion is bugging me. Least all I'll n3ed now is the alt upgrade and charge cables.
