There are many factors- temperature, how long the battery has been
sitting since it was last charged, whether it has been under any
drain (ie various memories and clock), etc.
I think this section of the Lead Acid Battery FAQ is exactly what you
are looking for:
If I read correctly, he recommends checking over the battery
(including testing specific gravity of the cells), charging it
properly, removing the surface charge (ie waiting 12-24 hours) and
then taking it to an auto parts store for a battery conductance test.
