Phantom01Pathfinder Posted November 11, 2012 Share Posted November 11, 2012 So every year i always get corrosion (i hope i spelled that right, ha) around the positive terminal. usually right before winter starts. I always use the felt pads under the terminals and spray terminal protector on neg. and positive posts. None of my parents cars have issues and neither does my wifes 328i. any ideas?

Towncivilian Posted November 11, 2012 Share Posted November 11, 2012 Overtightening a battery terminal can crack or damage the battery case around the post, which leads to constant corrosion. The only fix for that would be to replace the battery. Make sure the other ends of the battery terminals are clean first, though. Link to comment Share on other sites More sharing options...
Trogdor636 Posted November 11, 2012 Share Posted November 11, 2012 Clean it up with baking soda, and then put vaseline on it. 1 Link to comment Share on other sites More sharing options...
theexbrit Posted November 12, 2012 Share Posted November 12, 2012 Trogdor636's fix worked for me. Link to comment Share on other sites More sharing options...
96Pathfinder4x4 Posted November 13, 2012 Share Posted November 13, 2012 I know it sounds weird, but I think it's a Pathy thing. I've used Battery Terminal Protector for years, on various makes and models. This is the first car that the battery terminals accumulate deposits after using the spray.

Slartibartfast Posted November 13, 2012 Share Posted November 13, 2012 I shoot a little WD40 on my battery connections whenever I'm fooling around under the hood. No felt pads, no special sprays. No corrosion issues yet. Maybe the shape/design of the Pathy battery connectors make them easy to overtighten? Link to comment Share on other sites More sharing options...
