[APML]: Pentax 6x7 external battery?

[charles@jon.cjfny.org]

AS>I just purchased a (used) Pentax 6x7 "lockup" body, waist level finder
AS>and 105/2.4 lens, all in excellent condition.  I fitted the body with a
AS>new battery, but after only about 1 hour in exposure times (about 5
AS>10-minute exposures and several shorter ones), the battery condition LED
AS>is already dimming.

I have a 6X7 external battery pack sold by Pentax. I slip it into my
pocket, and disconnect the battery from the pack while the exposure is
running, and then re-connect it when I want to finish the shot. Its also
great for cold weather, to keep the battery warm with my body heat. A
local camera store can easily order it for you. The only problem was
that I had to cut a small hole through my camera platform so that the
cord could fit through.
