Battery problem, sulphating (?) terminal

I guess we will just have to disagree, then. Thanks for the conversation, though!

seal it

Clean your connections with baking soda, use any spray terminal sealer from auto parts store, apply several coats and you should be good to go for a season. I have also used grease [lithium or wheel] mixed with baking soda and packed it around the terminals, with a treated battery mat over the cap vent holes.

I just use vaseline, and have no corrosion problems at all.
