What do you mean?  If I put a good regulated 15V across a battery pack
I'd better dang well get 15V.  When will the voltage rise?

Either you're saying put a constant current across the battery (and you
don't tell us what that current is) or you're saying put an unregulated
15V and small amperage transformer based supply across the battery (in
which case you're over speccing the transformer and you'll destroy that
in the process)

Perhaps you meant put 15V across it and measure the current (waiting for
the current to suddenly go up)?
