Just an interesting point for those of us using AC Delco side post batteries. I had one in my IROC for several years and I could not understand what was making the positive side constantly corrode with that greenish powerdy residue. I cleaned it many times, and tried everything from baking soda, peterolum jelly to dialectric grease but nothing kept it away. I thought it was something in the electrical system of the car causing it.
I come to find out, its the battery, and I'm not the only one.

Just thought I'd throw that out there in case someone else is pulling their hair out over this.

cheers.

 

Great. I just bought a Delphi battery.

 

And it gets even worse than just the corrosion.The positive terminal WILL completely pull out of the case.
