Has anyone had the issue of the (+) battery clamp corroding? I've cleaned mine off two weeks ago and the greenish corrosion seems to be coming back. I did apply come vaseline/waterproof grease to it but no luck. I seem to have good ground and car runs fine so not sure what is causing it. I might end up replacing the terminal completely but was curious how others addressed this first.

 

Could be environment related, maybe a leak somewhere thats super precisely ending up on the terminal (rare). More then likely however its a old battery on its way out that causes this. While usually I`d suggest getting your battery checked out at the local parts place (free) a good old handy way is to figure out whats your voltage after an overnight on your driveway (anything below 12.4 is considered bad).

EDIT: Did you find all the grounds and check them indiviually?
In terms of car runs fine, usually the warmer weather you`re not going to need alot of amperage to start.

 

make sure its not the whole cable thats corroded also..my wifes car was like that kept coming back, even after replacing the terminal until i found out the whole cable has some corrosion.

 

Is the battery post producing it? Once a battery is left for a year it'll continue to do so, it's what I found.
