Hi

I read in a 1977 book about battery, that wen you have a lead-acid car
battery who are sulphated , you can put one or two tea spoon of Epsom
Salt in each cell of that battery, and it's suppose to take out the
sulfate deposit in few days.

Anyone know if that work ??

Any other suggestions ?

Thank

Gaetan

Yes in some cases this will work, I have used it to rejuvenate old deep
cycle golf cart batterys.

Please bear in mind that that you do this at your own risk. I will assume
no respsonsibity if you kill your battery totally. The advice is free and
worth every cent your paying for it.

The mechanism behind this is as follows, The Magnesium sulfate (Epsom
salts) combines with the sulphuric acid and forces the lead sulfate to
precipitate to the bottom of the battery. To do this properly you should
of course watch all precautions for acid splatter. After adding 2
teaspoons of Magnesium sulfate to each cell I carefully shake the
batterys so that the Epsom salts are mixed in with the battery acid.

After approximately 24 hours I start cycling the batterys by having a
neighborhood kid drive the golf cart around the block several times till
the batterys are discharged, then immediately recharging the batterys and
repeating the process over a period of 3 or 4 days.

Results? well I have done this with 3 sets of batterys.. (18 in all) and
only had 1 battery that wouldn't revitalize.

It is EDTA, a chelating agent, that removes heavy sulphation
from batteries.

FWIW,

I don't know if this applies, but when I was in school, the mechaism
described for a "shorted" cell in a battery was the collection of junk
in the bottom of the cell. The precipitate, if conductive, might
cause this. Oh, the discussion was about jump starting a car that
had a shorted battery. The end result can be an exploding battery.

I have heard that if you take a battery down to no charge and then fully
charge it reverse (takes weeks). Then discharge it to nothing, and
fully charge it the correct direction you can fully repair it.

I have a new battery that has become nothing. (even though left on
standby charge for the years) I'll try it.

I'll let everyone know the results.

An old friend used to 'recondition' lead acid auto batteries by cycling
them hard with a booster supply to, in his words, "stress the plates and
get the crusty stuff to break up and fall away." He then flipped it
upside down and drained away the liquid and sedimentary crud. He'd
flush it with a garden hose, then with distilled water, then refill
it with fresh acid and deionized water. The batteries performed almost
as new (the plate area was somewhat reduced, so capacity was minutely
diminished -- not enough to notice in use, but measurable with equipment).

He made a living at this for a time...

Good luck and be careful!

Hmmm...wonder how he got rid of the "liquid"?

Battery acid is nasty stuff...:)

I don't know about epson salt but the salt I have used and is
used by many is EDTA for desulfating batteries. EDTA is tetrasodium
which is a food preserver. Home Power Magazine wrote many a articles
on this. If need more information let me know or check out the NewsList
site 'alt.energy.renewable'.

Yes, be very careful. a battery reconditioner near here had a battery BURN
down through a wooden crate and through the concrete floor of his shop. took
about 20 minutes to do the job. a lot of heat was generated, and although a
rare occurance, has happened.

That does happen from time to time. In almost every case (certainly in
the garages that I've had personal contact with) it had the same cause
-- someone refilled an empty battery with acid, but used concentrated
acid straight from the carboy, instead of diluting it first.

Spills of "battery acid" strength will make your concrete fizz a bit,
but it won't eat its way through wood in any dramatic fashion.

Couldn't see this and not reply. The "old" acid has Lead Sulphate in it
which will, if poured onto the ground, will contaminate the ground with
lead. Anthing that grows in that dirt, if it can, will have lead in it.
If animals eat what ever grows in the soil, they will get lead
poisoning. If one gets the dirt on themselves, or breathe the dust, lead
poisoning may follow. Please don't dump old acid or batteries. Find a
way to recycle everything including the liquid from old batteries.

Lead lasts forever. It will catch up to you, you children, or pets some
day. Thanks.

Duh! Lead is an element, of course it lasts forever. The question is
what is abnormally high!? In the ole Britannica I see that Pb, lead,
is already present in the earth's crust AND soil to the 0.25% level.
I doubt that the leaching of lead by acid will be significant when
disposed of. This argument is similar to the last guy who claimed the
sulphates will be "bad" for you, when nature uses them constantly!
Injectable drugs are all sulphates, as are some components of cells
and blood! Sulphates are also part of edible foods! This is why we
have rain, to rinse those materials down and dilute them to tolerable
levels. There may be no REAL tolerable level of radiation, as in
nuclear, not as in HV power lines, but remember the Selenium scare a
while back in some wetlands, and then they realized that the amount
consumed was actually less than the animals who live there actually
NEED and that their area had a DEFICIENCY!! Just as we have a zinc
deficiency if we live in North America, as opposed to Europe! And that
stuff has CADMIUM hanging around with it in its mined form! According
to the Brittanica, plants do not absorb lead if it is increased in the
soil. So if you don't eat a lot of dirt, I think you're kiddies are
safe! A little knowledge is such a stupid thing, not to mention
dangerous!

Just because something is an element doesn't mean it will last forever.
I'll bet even you can think of several examples.

No?

O.K., at the most elemental level, how about two hydrogens that fuse to
become one helium?

At the other extreme (or close to it, anyway) how about the unstable
elements (trans-uranics?) that spontaneously decay into other elements?
Or how about, say, 92 U 238 when its nucleus gets hit with a neutron?

Or how about _any_ element which transmutes because of a nuclear event?

Aren't we picking nits? Lead is an element - and about the most
stable element one can think of. Forever is a long time (much longer
than I care to think about or worry about a few random cosmic rays changing
my nice elemental lead into gold.

It does doodley. They enrich Uranium by REMOVING the 238 from the
smaller quantity of 235, which is what they need to fission properly!!
Those are the cavity magnetic ionic mass separators, like the ones
Saddam Hussein got the shit bombed out of!! Well, you're 0 for 3,
John, care to make it 4???? I'm surprised you haven't tried to look up
some radioactive lead isotope. Maybe you don't know WHERE to look,
John. I'm REAL fucking sorry you're such an ass, but you started a
pissing contest for nothing, so get pissed on!! Next time either try
the CRC handbook of Chemistry and Physics... or better, get a life!
And learn some basic organic chem, okay! Any FARMER can tell you that
sulfates are not a problem! And lead simply doesn't hang around in
solution when there are lead plates in the solution, not to any
significant degree.

Unfortunately (*grin*), I have to go with Steve on this one, John...

The reaction you are speaking of goes like this...

H1+H1 --> H2 + e+ + v + 0.42MeV... He2 isnt stable... Shortly after
the positron annhilates with an electron and you get about 1.02 MeV...

: smaller quantity of 235, which is what they need to fission properly!!


: Those are the cavity magnetic ionic mass separators, like the ones

Actually... The Iraqi's apparently had several different types of
separators in process... (Not just Calutrons... Which I believe is the
same thing as a "Cavity Magnetic Ionic Mass Separator"???)

Of course lead lasts forever, the more correct way to say it is that it
will last forever, assumming there are no transmutations due to
atomic interactions. However, 99.9% plus of that lead will still be
around on earth, when the sun goes nova. A few atoms will have been
transmuted, yes but not many.
