Not sure if this happens to everyone or not but it seems about every 2 yrs or so I have to replace the battery connectors.Does everyone seem to have to do this?. Now I am kind of curious if there is some sort of dielectric grease to put on the battery terminals/connectors to help with the corrosion of the connection at the battery?
Thanks
Chris.

you could use vasoline instead of di-electric grease, alot cheaper.

Ok I did think of trying that but I have always thought that Vaseline would not allow the power to transfer properly from the battery to the conector.
Thanks

"dielectric" actually means non-conductive. You don't even have to take my word for it - it should be in any dictionary. Vaseline should work just as well as dielectric grease on battery posts. The main difference between the two is that Vaseline is petroleum-based while dielectric grease is normally silicone-based. Silicone is better for rubber and plastic parts (connectors) and haqs higher heat endurance.
There is such a thing as conductive grease. It's black in color and very expensive - best place to find it would be a well stocked electrical supply place where professional electricians go. It's mainly meant for use on aluminum wire connections in homes/buildings.

ok then so can vaseline be used on battery posts and battery connectors to prevent corrosion but still allow excellent power transfer from batt to conector?

Yes.

-and use dielectric grease specifically on multipin connectors to protect from corrosion and prevent current from traveling through the grease from one pin to another.
