Batteries and Vaseline

Anything wrong with the old habit of using Vaseline (Petroleum Jelly) on battery terminals to protect them from corrosion?

    I was surprised and disappointed to discover corrosion on the terminal of a lightly used AGM battery. (Positive terminal only)
  • No problem. Pretty much any grease will work. Be liberal ! Best to remove the cables and do around the the posts and then replace the cables and do them.
  • Spray is easier. My old habit is the easy one that works.

    I don’t see a problem with that or spray on battery protector.
