How does a lead-acid battery work?

A lead-acid battery works by electrochemical reactions. During discharge, sulfate (SO4) combines with the lead (Pb) of both plates, forming lead sulphate (PbSO4). This process is reversed during charging, with the lead sulphate (PbSO4) driven back into the electrolyte (H2SO4).

How do you test a battery?
