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).

so about 50p currently

Which is exactly a fiver for a 10Kg battery, although the one I replaced
was 14Kg.
