As I stated and your statements concurr.  Careful of the qualifier
**useful**


The voltage is influenced by the concentration of the reactants,
including the acid (pH) to some extent. That's why the voltage drops
as a cell discharges. The Nernst equation gives a quantitative handle
on that if you know the concentration right at the plate surfaces,
which is hard to measure.

Lead-acid is pretty well understood and explained, compared to
Lithium.
