I use a 34 amp hour marine battery (a small battery, about the
size used in rider mowers) for my G-11 /w DSCs and it lasts all
night long even in the winter.
I use marine batteries because unlike car batteries, they are
designed to be discharged almost completely without harming
them.
I also use two other 34 amp batteries to run my laptop and
CCD camera but I'm fixing to upgrade to two 68 amp hour
batteries because the smaller batteries are just borderline enough.
I have noticed something about marine batteries (don't know which
kind you have), that if you charge them up after a few weeks of
sitting, they don't have as much capacity. The longer they have
sat, the lower their capacity is.
However after I cursed at them for running completely down
in say 1/2 the time they should have and charge them up
fully again. Then they have full capacity and last much longer.
So what I now will do if I haven't been out for a month or so is
charge them up, run them down, and then charge them
up again before I go out.
This is called "cycling" by NiCad users. I don't know if the
concept applies to these batteries or not, but it definitely
makes a big difference.

The battery pack that I use claims that a radio or TV can be
operated for 20 hrs. On several occassions, by freshly charged
battery went dead driving the G-11 with DSC. I couldn't understand
this at first, and later concluded that a fine layer of bubbles
formed over the battery plates made it appear dead. So when it
happened again, I simpley shook the battery as hard as I could but to
no avail. Any comments, or does the G-11 draw about 5 times the
current of a radio or TV
