Unusual and frustrating issue:

I'm gathering that acid vapor has deteriorated the
powdercoating on my firewall battery rack hold-down.
That in turn, has made a white "mush" between the
terminal and the rack. Although I've cleaned out much
of the mush, and used baking soda, followed by NoCote,
I'm still getting arcing on charge, and it appears as
though the top of the batteries have melted/burned a
bit.

Seems to me that I need to
1) Pull off the hold down, and have the coating
re-done.
2) <Possibly> Swap out the battery which has had some
burning around the terminals. (7 mos. old)
3) Hit it hard with the NoCote and/or the absorbent
yellow padding that absorbs acid vapors.

Anyone else had this happen? I'm frustrated at
puddling of acid around the battery tops, meaning that
the quick caps (all that US Battery is selling right
now) are indirectly responsible.

Would you still drive your car if the tailpipe came out of the steering wheel? Are you saving any gas for your kids?

Hello Bob,

That's why I do not use the common type of battery caps or even the single
type that are press on. They seem to leak acid all the time. Replace them
with a locking type with a o-ring cap and now they stay clean all the time
even at a 50 amp charge.

I never tested out the power coat to see how acid proof it is, but there is
some companies that make battery clamps that are painted with a epoxy
coating, so that what I did, I painted my battery boxes with the epoxy
coating that is apply on sinks, tubs and shower stalls.

This epoxy coating is a two part mix that comes in a sink and tub recoating
kit I got from Home Depot. This stuff is real thick, I thin it down with a
epoxy thinner to make it flow out better.

I just put 2 of the quick caps (3 ganged) on my Trojan T105,
and after 2 weeks I found acid had leaked out of the center
cell cap, even though the water was low. I did not like
the trojan grouping of 3 caps. I'm planning to find
individual caps. (My other 46 cells were dry.)

The quick-caps usually don't seal well. I haven't had a problem getting
individual cell caps when ordering from US Battery - just ask for them. If
you buy from dealer stock, I suppose it might be more difficult to get the
"good stuff," depending on how cooperative your dealer is.

Was told by my local Interstate Battery vendor that no
more US Batteries will come with single caps. All
will be speedcaps.

On another note, Mike and Shari told me to use Epoxy
powdercoating, but the powdercoating dude had used
POLYESTER. Don't know if that information was in my
copy of "Convert It", but hopefully that change will
make a difference.
peace,
