Merely replacing a battery won't (usually at least) cause any problems with
things like that.

All the vaseline does is prevent oxygen from getting at the terminals and
causing that nasty whitish oxidation!.
The clamps go tight enough around the posts that putting the vaseline on
before won't matter, as it'll just get squished outta the way!

Vaseline is the cheap solution....you can buy anti-oxidation stuff from
electrical suppliers.
Novalox is something I used to use on ground rod connections.

Some of these products have metals embedded in them. This allows conduction
but still keeps oxygen out.
You don't want one of these ones....don't want it going from your + terminal
to the chassis (essentially the - terminal).

They still lose water like the older ones, just slower.

On a Jeep that has heavy battery use they will fail faster than one you
can top up easily.

That said, most of them can have the top opened so they can be topped up
with distilled water which will vastly extend their life.

I knew a company that sold used batteries to all the car lots. They
collected 'dead' maintenance free batteries, opened them, topped them up
with water, deep charged them and sold them with a 1 year warranty.

I talked to the owner and he stated he almost never has a warranty claim
and if it happens it is right away because the battery really was a dead
one.

They do not make much if any difference with terminal corrosion because
they still do outgass.

Same goes for the spiral cell lead acid batteries like Optima. Optima
has a slower terminal corrosion rate, but it still corrodes them to the
point of a failed connection on both of my Jeeps after a couple years.

I have never understood why aftermarket car batteries don't have
sealed lids (screw-in service plugs) and vent hoses, like motorcycle
and aircraft batteries. The oem battery on my ex-Saab 9-5 had one. The
oem battery on my wife's Audi has one.

I have _never_ seen a vented aftermarket battery. No way can sulfuric
acid venting from an unsealed batter be considered good for your
vehicle.

Rant over.

I'll second that, but they will also corrode at the terminals, if someone
breaks the seal around them.
This is usually caused by hammering terminals on, or twisting them off with
pliers, rather than using a terminal Spreader and puller, Items 2 and 3-5
here.

or slamming it around with no hold-downs.
Be good to your new battery, and it will be ok.

Hi Bill,
They work for me: http://www.billhughes.com/battery.jpg I do use
baking soda from time to time to wash off and neutralize any acid, then
paint the terminals. Using a petroleum product will cause a black like
substance to seep in and ruin the connection.

Ue a liquid that will penetrate everywhere after installing the cables
onto the terminals. I have used Boeshield T9 for many years and I
never have even the slightest trace of terminal corrosion. The
disadvantage is that it is greasy and you should clean it off to bare
metal with lacquer thinner before reattaching a cable. Then reapply.

I've seen a combination of poorly tightened connectors and vaseline
cause a zero start syndrome. If the connector is loose enough to let
the vaseline melt down into the tiniest gaps, you can lose enough
conduct area to cause problems.

I used to use a very high temp military dow silicon grease, but
was a pita to deal with. Nowadays just use the corrosion washers
and a shot of ordinary old clear paint--cheaper than that special
battery paint.

I've been using maintenance free, sealed batteries since they first came out a

battery acid on your clothes with sealed car batteries. Ruined a brand new
pair of 501 Levi jeans when battery acid got on them when refilling old
battery.
