My longest exposures so far with either original 645 or Nii has been
around 15 minutes. On several occasions in temperatures well below
zero celsius; when alkaline batteries perform poorly. No problems at
all.
If you notice any problems, there is an external battery pack
accessory for the 645 cameras; with a generous length of cable to keep
the batteries inside your clothing or in another warm place. I do hate
the thought of being nailed to one spot for 6 hours, though...:-)
Cheers,
Jostein

Manual says, that fresh set of 6 AA batteries (good alkaline
batteries) can take 250 rolls of film.
So, i have good Duracell alkalines installed.
I think, that i can get more than one 6 hour exposure from fresh
batteries.
Whatever, the original question was how to keep fresh batteries, and
take long exposure :)
OK, i still have unfinished roll of film in 645. I'll post results
tomorrow.

are you kidding? run out of AA batteries by just keeping the
shutter open?
how long is going to be the exposure - months?
I don't know about the 645, but Pentax indicates in the 6x7 manual
that a fresh battery will give about 6 hours of shutter open time.
The 6x7 runs on a single PX28 (6 volt) battery, which is
essentially 4 S76 batteries in a stack,
