Default Using Vaseline on Battery Terminals

Whenever I am not using my van, I take the battery out and I put it in
my house.(too many of those ''spread the wealth'' people around here) I
don't tighten the battery clamps, I twist ''tighten'' them on there.I
have an old battery cable wire tied under the hood.When I remove my
battery, I let that battery cable dangle out from under the hood.That
makes it look like/seem like there is no battery in my van.Sometimes, I
have to use a round wire brush to clean up the battery cables clamps and
the battery terminals.I might try using some Vaseline and see if that
helps.

Give the man a trophy.. This is the best answer.

Actually, it plays little part in the equation. The contact will be made
through the
petroleum jelly by clean metal contact. Corrosive (oxidative) films can be
far
more efficient insulators than this layer of "grease".

That is one reason that capacitors can be made with HUGE capacitance values.

Grease is good but it has a chances to reduce the charging power.whereas, Vaseline it won't it allows proper power to charge quickly.

Beating on a battery terminal can allow a car to start - if the problem is a poor terminal connection. I used to start my Ford Taurus by opening up the hood and whacking on the box that housed the relays. They were all in a single sealed box that didn't allow access to the relays. It one of the greatest idea Ford ever came up with! The fuel pump relay was kind of flakey. Sometimes you just got to kick car ass.

So what is "grease" that makes it different than "vaseline?"

My guess is that any kind of grease would work on a battery terminal - even dielectric grease. The terminals usually get flakey because of corrosion between the contact areas. Anything that seals off those areas to air is a good thing. The most important thing is that the grease does not melt at the working temperatures.

You need grease that conducts electricity. I forget the 3-syllable
word, but they sell little envelopes of it at autoparts store, just for
electrical things.

I've never used anything on my battery posts and in 55 years I've never
had corrosion. But I do use the red and green felt washers sold for
batteries, they are great and afaict last for years.

But once I had a switch or something filled with grease at the factory,
and if I rebuilt it, I replaced the grease with the stuff above.

I would think vaseline would be wet and runny when the weather is hot.

It one of the greatest idea Ford ever came up with! The fuel pump relay was kind of flakey. Sometimes you just got to kick car ass.


I had a '65 pontiac, almost new, and every time the lights were left on,
the car wouldn't start until I reached under and pulled the cable at the
starter motor a few degrees around the stud it was attached to. I got a
buzzer that buzzed if the lights were left on and that stopped that
problem.

And I had a convetible top motor for which I had to open the trunk and
whack the motor with a wrench. As time went on it sometimes took 3 or
more whacks, but once it started runnign it always ran fine until the
top was up or down as the case may be. This went on for almost 2 years
until I had to replace the brushes in the motor, but the brushes I
bought, though the right size, had copper braid connectors that were
much smaller than the original (they were meant for a smaller motor) so
I wadded up a little piece of aluminum foil and put it between the brush
housing and the spring behind each brush. That worked fine for years.
