If you find a GPS you really like - you'll probably put up with whatever it
uses for batteries. I was just lucky that I liked the size & capabilities of
mine - and it used AAs. I guess it was midway between a requirement and a
bonus ;-)

I know I sound like a shill for Sanyo (I'm not), but I can't speak too
highly of the Eneloop AAs. All my previous (good quality) NiMH AA cells
would lose charge over a couple of weeks and I had to hustle round and
charge them all up before a trip. It was a pain. The Eneloops trade off a
little life-span but employ tricks to hold onto their charge tenaciously - a
bit like Lithiums do (but at a much lower price). Otherwise they just act
like any good rechargeable. I love them. 

A couple of AA tips that work well for me:

(a) When I buy cells, I mark them in pairs with a number (1,1 2,2 etc) in
heavy black felt-tip pen (bad-light readable). As everything I have uses
them in 2's or 4's - they can stay together as pairs through their lifetime
of discharge - recharge cycles. I believe that gives them a better life
expectancy. As the numbers increase (with each new purchase), it also gives
me an idea of how old they are - just by looking at the number.

(b) I sew up simple rip-stop nylon pouches for sets of 4 AAs - just large
enough to have them lie side-by-side (like spoons or wrenches in a fabric
fold). The bags weigh nothing. With a tight velcro-ed down flap over the
open end of the 4 battery 'tubes', the bag winds up being only a little
bigger than the 4 batteries. It keeps them clean and stops them shorting out
on anything (or each other). It also makes them easy to count and keep
organised. An empty bag mean batteries missing - find them ! I also preserve
a simple routine - nipples-out are 'ready for action', nipples-in need a
recharge - you can tell that in the dark. 

Hope those ideas give some of you some help - or just a laugh ;-)
