I just bought a new Interstate Megatron battery, But before I install it should I use those green and red terminal washers ? Do they really work ?

I would, if it prevents any problem its worth it to take a second and slip them on.

Fartman, Your entire reply is sig worthy-

a cover would be better. The washers just let the dumb a$$ know which one is pos.(red) and neg.(grn./blk).

No, that's not all they are for. they have a chemical that is supposed to react and prevent corrosion. I always use them. Cover on the + terminal certainly doesn't hurt either.

Get the anti-corrosion spray. It works. Along with the felt washers and you should have little corrosion problems.

I have used those felt washers. i still got corrosion. They didn't work for me but it has for others

I heard that if you put a little bit of vaseline on the terminals, it prevents corrosion.

NO. Sorry but I work at a 76 service station and 9/10 when we see a car with those things they are all corroded and nasty, once they get corrosion on them they tend to collect it and are then Junk, do yourself a favor and do like Tony said and get terminal protector spray, we buy ours from Napa and give the terminals a good shot every time and we've never had a car that had the spray come back with nasty terminals.

Oh and it may sound hokie but to clean the terminals we go to the stock room grab a bottle of Coke , pour it in a cup and let the Battery cables soak, you'll see the crud and corrosion float to the top and it will literally be smoking and bubbling, then follow up with terminal cleaner and protector.

-END RANT- :thumbup

:EDIT: Oh by the way we sell Interstate batteries and IMHO they are great batteries with clean terminals they usually last 5-9 years

I have never had any luck with the felt washers either. Get some protective spray (I use the CRC stuff) and some terminal covers and you're good.....

I'll get the spray, Thanks fellas-

I have always used the chemically treated felt washers in conjunction with Permatex Battery Protector & Sealer and I have never had any corrosion whatsoever.

Then again, I keep my battery and engine compartment clean and in good repair...

Forget about them they are worthless.

that's exactly what I do. I just think for folks having a problem it's a case of putting a batt in and forgetting it for a few years. I keep everything reasonably clean and there are no issues.

If they are the good ones with the chemicals they are great. Corrosion is typically caused by a battery venting through the area were the post connects. The washers do a great job of trapping the gases and preventing corrosion... If you end up with a really gassy battery then eventually the washers will stop working... The spray works very well too...

YES YES YES, use the red & green felts but make sure the cable ends are all the way down on the post so they touch the felts, they also prevent corrosion from spreading to the cables right there.....

I use anti-seize on the battery cable end and bolt threads to prevent corrosion BUT common sense would dictate that you will need to change felts periodically because they do get absorbed....

They're cheap enough for preventative maintenance.....

Good Luck ~ :thumbup

I've used em since i first got my truck. The PO didn't and the terminals were corroded to all hell. Once i got a hold of it i cleaned it up, had it charged and used the felt washers when putting everything back together. To this day, with the same battery, i still have zero corrosion.

As JK pointed out, they do need to be replaced a couple times a year.

I've never had a problem with the felt washers, and I've always been told to smear some dielectric grease on the "top" of them before installing the cables.

I figure they can't hurt, they're cheap as hell, so it's not like you're wasting a ton of money if they really don't do anything.

they are worthless yes they a treated with stuff to help. however the vapors are the main problem so the spray a cover or nothing and get a optima

The spray works where it is sprayed and not much else IME.
Vaseline and No-Ox-Id grease same thing, too thick.
The felt washers by themselves don't do much either. :/

Motor oil in my experience works the best and the felt helps store some oil.

Motor oil isn't something a service station can use, it's too friggin messy
looking. :/ So BB33 won't have much experience with motor oil and other
snake oils, just store bought and approved sprays and stuff. Doesn't mean
the motor oil can't be just as good in action, it's ugly as all get out tho. LOL :)

Motor oil coats the metal good and all the metal parts need are protection
from the acidic air anyway. If you have a leaky post there ain't nothin going
to stop that situation. :) Just catch it soon and keep it clean until you get
another battery a few years later. BTDT too dangged many times. :/

At 20 years and 3 months I got my FE engine over hauled and bought new
cables. The originals were still like new but just wanted something that didn't
look so little. :) They had survived some pretty crummy batteries, batteries
that swelled up and oozed acid and all sorts of other problems too.

Sears delivered a new battery one time, across town, because their heat
resistant battery was anything but. LOL :)

If you ignore the nay-sayer posts and add all the stuff together, there's
enough information in this thread to keep new cables -working- like new for
over 30 years. :)

ps- back in the mid 70's I noticed the lead/acid battery terminals at work not
doing so good with the no-ox-id grease, it seemed too thick, so I thinned it
with motor oil. Well when I was running low, I just added some more motor
oil. Ended up doing that a few times since it was working so good. Finally
decided to try straight motor oil and found it worked the same. {shrug}

I'm gonna say one thing, and keep it more compact ;)

If motor oil and grease is anything like dialectric grease, it's being misunderstood again. I've told people time and again Dialectric grease is NON-conductive, and is meant as a grease insulator inside spark plug boots and what not, NEVER ON THE CONTACTS.

The spray you can buy to protect terminals is meant for the tops after you have established contact, the felt-chemical stuff for the bottom. You need to have a solid lead-lead contact.

i use anti-sieze on my terminals to prevent corrosion and it works just fine. Used to have crazy trouble with my pos. terminal gunking up every month or two.

For sure, BTDT in 1972, scraped down to shiny lead, smeared the battery
terminals and cable clamps down with no-ox-id grease and the wife got stuck
in town "no start". Mentioned it to the Signal Supervisor and he laughed and
said he did the same thing when he first hired out for the railroad too. LOL :)

ps- Knew my post was long but it's the one thing I know a little bit about? ;)
pps- Never had that problem with motor oil.
ppps- It's handy as anything, when you change the oil, wipe the battery
down with a rag and add a few more drops of motor oil to each terminal.

Have felt washers and also use that spray. Have yet to have any corrosion issues (well over a year and they still look new). I spray it on the terms before I put the connectors on and them give the hole setup a good shot of the spray. Down side for me though is the stuff makes a sticky mess when spraying. Take the good with the bad I guess. ;) I also spray it on the solenoid as well.

Red/Green Felt + Battery Brush (cable and batt. terminal) + Just-over-snug tightness + dielectric grease = Good connection, no corrosion.
