What causes corrosion on the posts of a car battery?
Battery corrosion around the posts of the battery is caused by the sulfuric acid and hydrogen gas vapor that can escape from the battery. Sometimes this vapor is vented out of the top vent blocks on the battery, but other times, small amounts of this vapor leak out in the area between the posts and where they seal to the plastic battery casing.
What should I do if my car battery is leaking acid?

Why do you need grease for car batteries?
Battery terminal grease also provides great protection for non-automotive batteries. Marine applications, ATV, lawn and other small engines that operate on a battery are subjected many times to extreme heat. These batteries don’t offer the ability to use a washer on them, but do allow you to coat the terminal lugs, or bolts, with protectant.
