Do you guys use felt washers on battery posts on your car or boat batteries? Do they really help from corrosion?

Practice, practice and more practice, and if you think you're good practice some more (Cadman circa2006)
I would think on a boat they would just attract and hold moisture.
I've seen guys coat the washers in grease then put them on the battery to help fight corrosion. I haven't had good results with the washers.
Hi Mike.
Some are treated with a substance that seems to work.
Have tried with and without the treatment and there is a difference.
Now days with this technology AGM, Lithium no need.
The reason merchants push these is because they carry about 80 points of margin. Likewise the grease they hawk to prevent corrosion. My wife had a new battery installed several weeks ago and I noticed the felt pads and grease on the post. Yep they got me on that one.
They are soaking wet with it an corrosion compound, and I believe they do work a little bit so I do use them

Sold batteries for 31 years when i had my auto repair shop. Everyone got free felt washers. Was easier than dealing with the corrosion that was sure to happen.
Nope. But I do put dielectric grease on them and 100% helps.

I just use petroleum jelly. A light coating will last as long as the battery will.

Nope...........
I had my own truck for 50years and my own boat for about 45 years and have never used them.
On my pick up truck
On my vehicles I use CRC (red spray) and the felt washers. On the boat, I don't use them at all.
Learned from my Grandpa who was a Military / Farm vehicle technician that any motor vehicle that is constantly pulsed by the alternator should have this. The constant pulse created some kind of electrolysis from the moisture in the air and the lead on the battery studs. With marine batteries, they are not used long enough to create this electric field / pull to warrant it.
Not sure if it's true, but I've had great luck with batteries living well past their life expectancy following this.
Been fishin' since I was 5 years old...Thanks Grandpa!

Hey guys, thanks for all the input.

Yep. Easy to apply, zero corrosion.
