Short answer, though, 12.0V is about 50% charge for a 12V battery that's
just sitting on the shelf with no load/charge. Fully charged is 12.73V
or higher. If you're talking about under charge, the float voltage is
about 13.8V depending on temperature and type of battery.

On these UB8D 12vdc batteries, would you expect to see 12vdc or
something closer to 13.8 like you would with a car battery?
Thanks,
Mike
