I have an IR camera that uses a Compaq hand held computer. It is kind of like a PDA but runs windows similar to windows xp.
I have to replace the batteries in the computer every 3 years or so. This is the third time I have had to replace them. However yesterday when ordering them I found out that the battery for it is all but non existent out on the internet. I finally found them in a place in Canada and they are the 2200's not the typical 1500's or 1700's so I ordered 2 of them thinking that this may be the last time I can actually get them as they may be NLA from now forward.
So the question is how do I store the one battery that I am not going to use right away? I was thinking of putting it in the freezer wrapped tightly in multiple zip locks and I would put some desiccant in with it.
Anyone have any other ideas?

Store them charged and top them off every 6 months or so.
+1 for what bgkast said, don't put them in the freezer. In fact you should probably store them in a sand bucket for safety, being li-polys.
I seem to recall reading somewhere that lithium batteries prefer to be stored at 40% charge, topped up annually.
That may be for li-ion, but all my li-poly RCs have instructions to store them with the battery fully charged, and li-polys are dead forever if they discharge too far so you want to stay well above the fatal voltage...
I am wondering if my batteries are dying due to being under charged and being let go flat.
It's totally possible if they're li-polys. They self-discharge relatively quickly.
Especially if while in the computer they maintain the ram where all programs are installed except those that are part of the os.
Whoa, what kind of weird computer is this? And how much RAM does it have?
