battery acid = sulfuric acid (H2SO4). The Metal is lead (Pb).

edit: I'm an idiot - thought about a car-battery. Probably, because you mentioned battery acid.

When battery is fully charged, positive plate is lead and negative plate is lead dioxide.
When battery is virtually discharged, positive and negative plates are converted to lead sulfate.
