Does petroleum jelly absorb water?

Petroleum jelly does not absorb water over time as some greases do which is why it is preferential.

Is lithium grease waterproof?

lithium grease, but has the same waterproofing. capabilities. Handyandy - really. The reason I said this, is because in a car handbook (I've read all the books of all my previous cars), it recommends that you use petroleum jelly (exact words). I presumed that it might have more conductive properties than grease.

What to do with battery terminals?

the best thing to do with a battery terminal is to clean the post on the battery, clean the terminal, fasten on/tighten up the terminal on the battery for a REALLY good connection, THEN cover the whole terminal and battery post with Petroleum Jelly (commonly known as Vaseline in the UK as often brand names are used that way here) to prevent oxidation/corrosion of the terminals and pos
