Hey Guys... Talk to me about corrosion on the battery terminals. I went to move the wife's Chevelle this afternoon and it acts like the battery is dead and needs a jump. It happens as this car sits for weeks at a time without being started. Anyway, I pop the hood and there's a boatload of corrosion on the positive terminal and connector. I cleaned it all up and replaced the positive connector since it was broken and she fired right up. What causes the corrosion? Is the battery going bad? Is it because it sits without being run? Anything I can do to stop it? My trucks can sit for long periods of time without this happening. What gives? Thanks for your help.
