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,
