Jeff I have had vast experiance with batteries in the REAL field ie:
Wilderness Areas, and the only thing that makes sense is Alkaline battery.
You can get them in all sizes and they have lower weight/watt-hour than
almost any other battery. In the wilderness you can't re-charge a battery
so why have one?

So go to Wal-Mart and get fresh batteries just before you leave and after
a simple test you will know how long they will last. If your planning to
be longer, take a spare set.
