Well, this is my thing with "special" batteries - suppose you ain't got
a place to recharge it, overnight or otherwise. Apparently, they are
lasting longer than they used to, which is good, and certainly, such
would mitigate my desire to have "normal" cells, but I would still
choose "normal" cells over special batteries, all else being fairly
equal. Remember that you can get ni-cad or lith-ion AA/AAA/C/D cells,
and the recharging options are vast, from mains to solar and even wind.

Very bad advice.

Yeah, as I re-read it, it's worded dangerously, confusing the common
terms for "battery" with "cell" etc., but you can sub Lith-ion for AA,
just not _cell_ for _cell_ - it's battery for cell - see below.

If you use "standard" sized lithium-ion batteries in a camera designed
for "normal" batteries you'll fry your camera. Lithium-ion batteries
produce twice the voltage of alkaline batteries and three times the
voltage of NiMH batteries..

I'm not (just) talking about _batteries_ (or "batteries"), I'm talking
about cells - IOW, 1 lith-ion "unit" to replace 2 AA cells ("battery" in
common speech). However, I have AA (and AAA and D cell) sized NiMH and
NiCad "units" that are direct 1-for-1 replacements for "standard" AA, D,
etc. I also have a few _batteries_ that are lith-ion and take the
place of 2 (or 4) AA _cells_ - i use them in digital cameras, GPS/Nav
gear, etc. I have a backup nav setup whereby I can run my
GPS/Chartplotter. laptop, and a HH VHF via NiMH (or alkaline, NiMH, or
NiCad) trickled/topped off by solar or wind or via house batteries, for
example.

Here is the first link Google produced, and it appears to be a good one
(but I have nothing whatsoever to do with it, nor did I fully examine
it, and as such, I make suggestions either way as to doing business with
them):

(scroll down for lith-ion info and replacements)

So, if one wishes to get non-"standard"/alkaline "batteries" for
something, make sure that you are getting the right power "unit" (and
charger) for the intended device. AFAIK, the NiMH and NiCad "AA", etc.
_sized_ units are 1-to-1 replacements for the "standard" alkaline
counterparts, but ??? - the packaging should clearly indicate such.
