[MV] Copper pennies on battery

Couldn't sleep, so I thought I'd ask:

Why do copper pennies taped on to the surface of a lead-acid truck battery
prevent corrosion of the terminals? This 'hint' appeared in the latest issue
of MV magazine.

What is the corrosion composed of? Lead-sulfate mixture? Does copper-sulfate
then form instead?

Thanks to all replying ----
