That is not done.
The acid is part of lead smelting anyway - lead sulphide its the usual
ore: when visited a big lead smelters in france they were also smashing
batteries and it all to the mix and dealing with the acid as part of
their general processing.
"Galena, the most common mineral of lead, is primarily lead sulfide
(PbS). The sulfide is oxidized to a sulfite (PbSO3) which thermally
decomposes into lead oxide and sulfur dioxide gas. (PbO and SO2) The
sulfur dioxide (like the carbon dioxide in the example above) is
expelled, and the lead oxide is reduced. Anglesite, Cerussite,
Pyromorphite, Mimetite and Wulfenite are other lead ores.
Other elements frequently present with lead ores include zinc and

That's interesting, the local (national chain) Tyre/Battery/Exhaust
place wanted to *charge* me a couple of quid to "dispose of" the old
one. I took it to the tip where they collect them for free. Never
thought of asking someone to pay to take it away.
Does it cost more than a fiver each to get a scrappie to collect a bulk
order of scrap car batteries? (Such that the fiver each he pays you
doesn't cover the cost of ringing him up to come round and collect
At one of the council scrap yards I've used, all the lead acid batteries
are chucked into a skip. I have visions of the driver trying to lift it
up and wondering why all the batteries are still on the ground and the
skip has no bottom. At another site, they're all stacked carefully,
keeping them the right way up.
I don't recall the dates now, but something like 20 years ago, the
industry got around 90% of dead car batteries back to the manufacturers
for recycling, because the value of them was enough to pay for their
return. Then the government introduced recycling certificates to
make sure none of them were being discarded, and the recyling rate
plummeted due to having to buy the certificates and process paperwork
for each dead battery. As lead prices have risen, this does now cover
the recyling paperwork overhead and the recycling rate has risen again.
