They probably are. I think I may need a new one. Or I should at least try disconnecting and reconnecting.

Once the battery post is clean & connection made, I’d recommend a protective spray or even a nice, thick layer of petroleum jelly. Keeps it nice. 👌

Using baking soda a bit of water and some time will also get rid of the corrosion along with neutralizing the acid which tends to come back otherwise.
Just disconnect and remove the battery. Wipe the battery with a paper towel covered in a paste made from baking soda. After, rinse it off with some clean water. Clean and rinse the car’s battery tray and Clamp like you did with the battery. Get a large-ish bowl or dish with some water and. Soak the harness terminals for a few minutes while adding baking soda until it stops fizzing. Get an old toothbrush and scrub the terminal with a baking soda paste. Rinse, re-install everything and you’re done.
It got my harness terminals from a crystallized mess from leaking to looking brand new (seriously) and none an issue for the past 4 years.
