Yup, been doing this for years.Be careful not to get Vaseline on rubber parts though, it will cause them to deteriorate.

Pro tip, add light layer of Vaseline to terminals and you won't need these or have corrosion issues. 100% guaranteed

Is this worth using on Lithium 12v batteries?

They inhibit corrosion so I suppose it depends on where your batteries are.

NOCO NCP2 MC303 Oil-Based Battery Terminal Protectors, Anti-Corrosion Washers, and Battery Corrosion Pads (Pack of 2)

90 day average $7.31
I feel a more common price is $4-$5

They go on this sale price occasionally.
Personally use then and feel they do seem to help the terminals stay clean

Last time I got this/something like it, it came with a packet of some sort of terminal grease to apply on top.
