Proper goop to protect battery terminals?
 
I’m getting my riding mower ready for summer, cleaning the battery terminals, etc.

Is anti-oxidant goop good enough or should I buy some stuff especially for battery terminal. I guess I’m just being a tightwad since I already have the anti-oxidant here at home.

Go ahead and use it. Something is better than nothing at all.

I've used a big glob of vaseline in the past, just need to block out the air.

I use silicone grease and it seems to work well. I think noalox is just silicone grease with suspended conductive grit so that when you torque it down the grit bites through the oxidization, I wouldn't be surprised if noalox worked great for battery terminals.

What we use on batteries per the manufactures
NO-OX-ID-A

I generally use Never-Seize, hasn’t failed me yet.

This is also a spec for a lot of the manufacturer's equipment such as MCCs, discos, etc.

I usually use plain axle grease for any electrical connection - battery, aluminum, etc. Anything that keeps the air out works just fine as an oxide inhibitor. Doesn't necessarily have to be conductive. When you tighten the connection, the grease squeezes out and you have straight metal to metal contact.
Only place you really need to be picky on what kind of grease you use is when you are close to another conductor that you shouldn't be shorting out to like a light bulb socket or a spark plug boot. There, insist on dielectric grease.

On the batteries for the gensets we install, we use dielectric grease.

Clean terminals and lugs require no grease. IMO of course.....lol

The terminals are clean now. Battery terminals tend to corrode or otherwise get funky over time.

I like the silicone for a few reasons. For one it's dielectric, you don't wind up with a conductive trace if it drips or runs. You'd think a dielectric / insulator in an electrical connection would be a bad thing but as @JoeSparky points out under pressure when torqued, it is squeezed out and you are left with metal to metal. It's in the gaps where corrosion occurs, there any grease will seal out air and prevent oxidization.

Silicone is usually the least likely to damage plastic or rubber, if you get oil or grease on rubber or some plastic, it will swell and weaken it.

And silicone grease is generally harder to wash off than others, white lithium grease and lanolin based grease hold up pretty well in water, better than regular grease, but I think silicone grease might be the best.

Ive always used this stuf on car batteries

Clean with baking soda and vinegar, then spray this onhttps://uploads.tapatalk-cdn.com/201...89b57150b1.jpg

There you go, getting all sensible on us again. :rolleyes:

Die electric grease is good, but on a lawnmower I just see it collecting grass n dirt!

Is this the red SH*T, HATE THAT STUFF when you are dealing with 240 cells this stuff gets on everything.

Sparling I hope, dielectric grease will conduct and if it melts and contacts any metal components of the engine will lead to self-discharge of the battery, in a UPS system it results in ground fault alarms..

It could be, I've never used it. I always used either grease or petroleum jelly.

I have had two riding mowers in 30 years here. Never once had corrosion.
But I do remove the battery from the machine after the last use each fall. And if there is anything on them they get cleaned then.
So they do get attention twice a year. But no grease or spray.
I think my new mower has that little oily felt washer under the lugs.

I had a part time job in a service station when I was a kid, did minor repairs and etc. The mechanic was a friend of mine and knew I was handy with electricity and electronic issues, so once in a while he'd have me look at one that had him stumped.



I fixed a lot of things by just brightening up the battery and ground strap terminals and lugs, greasing them up with silicone grease, and putting them back together. I go to where I did that before I'd even try to figure things out. A lot of times the connections looked fine and were tight, but this fixed things. I imagine the oxidization can creep in there, swell a bit and you wind up barely connected or no connection.



Years later maintaining the batteries for a telco CO, everyone used the manufacturer supplied terminal grease, those systems worked great and I don't ever remember getting a bad connection on a terminal.
