I know I can use it on spark plug boots, but I was wondering....   I bought  the Predator 7Kw generator from Harbor Freight and bought a battery for the electric start.  Hooked it up with some finagling because the battery had to go under everything and the terminals end up being reversed and so the cables jussst make it. I'll get some longer ones next summer.  That's okay; I got it to fit.  I'm not fully confident how well the terminal boots will protect the terminals so I was wondering if I spread, or sprayed some dielectric grease over the connections if  that would give added protection from rain,snow, sleet, or whatever.  I'm talking OVER the boots.   Anyoone know if that's alright ?

It should help with corrosion in the connections.

If I'm real concerned I fill the boot with the grease before I put it on. Keeps water and other stuff out.

Cover it good and then do something to prevent the mice from building a nest in the engine and destroying the ignition. Dont leave gas in the tank or carb. Stabil may work for awhile but after that it will need to be flushed out. Good Luck, Rick

I always use dielectric grease when installing a battery in just about everything, except like flashlights and things like that.  As stated above it will protect the terminals from quite a few things the most important is corrosion.

I've used both with success, prefer the dielectric grease covering the entire connection, sealing it from the elements. Its a little messy, but how offend do you change the battery?

Any time I have any suspensions of a bad connection I will get the grease out and apply to the connections, so far no problems.

That why I like the dielectric, I smear a little right on the post and inside the connector. Place together and tighten, smear generous coating all over on the outside, 5+ years later change battery at the first sign of trouble.

Use the dielectric grease. You won't be disappointed.

Really you can use any type of grease... Dielectric is just clean, oderless and will stand up to high temperatures. In low temp conditions (<100 F) you can even use petrolium jelly.

 

Basically when you use either all you are doing is displacing oxygen and/or battery acid.

Dielectric grease is a silicone based gel,,,  I love the stuff..  Petrolium jelly  is oil based,,as is ordinary greese.. So useing it on rubber boots,  ( plug wires )  and wires make it pron to rot..

 

Keeping a Batt clean is the key to a long life..and not let it over-charge or under-charge,,or freeze..

Very good point, petroleum and rubber do not play well together!
