Corrosion happens on the battery terminals when hydrogen gas is being released from the acid in the battery. This acid mixes with other things in the air under the hood of your vehicle, causing the corrosion you can see. Some batteries are “maintenance free” which means you don’t need to check the water levels inside.
How do I keep my battery terminals from corroding?
