Can Anybody tell me why i always find white powder on my battery positive post. i just changed the alternator and battery. the only thing wrong that i noticed, is that sometimes my gage needles go back and forth. Thank you

did you use that grease on the terminal?!

I forget the name...mine is purple..

Time to break out the Vaseline.

sounds like oxidation on the terminal, it happens when these parts (battery & battery cables) age, over time it will build up, it's not uncommon and happens to almost every car out there. Best thing to do is use a wire brush to clean the area and then use electric grease on it before you put it back on.

use bakeing soda and water mixed together to clean the top and posts of the battery to get ride of the buildup that your talking about.

coating the terminals with white lithium grease works well to, to help prevent the corrosion buildup

It's coke.

Snort it.











K seriously, it's likely battery acid that's crusted up, or as others have mentioned, oxidation. Buy some $5 terminal cleaners at canadian tire, and have at 'er.

why are you guy coating the battery terminal with grease, your just adding more resistance into the system.

Actually dielectric grease would not cause any problems. Used with Massive overclocking on computers. People who goto Sub-temps or phaze change systems use the dielectic grease in the socket where the cpu plugins to prevent mositure. Very Good at it's job.

Lithium grease.

i second using di-electric grease. it wont cause resistance problems because it acts like the coating on your wires, theres still conductivity underneath, but prevents water from touching exposed areas preventing corrosion build-up.

You have the Johnny Depp-package Focus. Nothing to see here... *snort* move along...

You guys think I'm kidding about the Vaseline don't you?

You should listen to the old schoolers more often:

Google "vaseline battery posts" yourself if you wish.

or you could just clean the battery cables and posts every few months. if your lazy by putting vaseline or any type of grease on the battery post, you must have more money than brains.
