Well lead scrap current going rate is 70p/kg, so if battery about 10Kg
probably a fiver!

Batteries seem to track at 50% of the clean lead scrap price,

If that 50% of the weight of the battery, or 50% of the weight of the
lead in a battery (which is apparently about 60% of the total).

I infer the weight of the whole battery is worth 50% of the clean lead
value.

Right, so you are getting 50% of the battery weight rather than 60%.
That's not too bad of a discount, given that the scrappie has to break
it apart, dispose of the plastic and acid etc.
That is not done.

The acid is part of lead smelting anyway - lead sulphide its the usual
o 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
silver.[2]"
