Man. My camera Canon A2000 goes through AA batteries like a dull knife

a charge longer than the other non rechargeable batts? I hope so.

Lithium non-rechargeables last a long time.

They are also very expensive.

I use Eneloop AA cells, which are rechargeable, and hold their charge
for a long time.

I carry an extra charged set with me.

for everyday use maybe, but they're great for keeping a set in the bag
in case you need another set. the shelf life is 10+ years.

I bought some Emeloops recently, as part of an effort to upgrade my equipment
a bit. My observation so far is that they don't hold their charge any better
than the "Enercells" that Radio sheck sells these days. However, they do seem
to charge cooler, which may make them last longer.

I don't doubt that you're right, but I'm not sure the point is relevant. If
you don't have enough batteries to cover the shoots you're going to do, you
should probably buy more rechargeables. If you get caught short through poor
planning or equipment failure, then yes, rush to the nearest store and buy
non-rechargeables (since rechargeables are rarely sold with a usable level of
charge). But don't buy them just to carry around in your bag for ten years.

obviously you should plan ahead and bring enough sets for a session
(plus a little extra just in case), but **** happens. having a set of
lithiums in the bag covers that situation for 10+ years, whereas
alkaline won't last anywhere near that long.

I don't know how good Enercells are (I have some older Radio Scrap
NiMH's that are still going well).

But recently I took out a flash that had Eneloops in it that hadn't been
fired in months and went on to shoot about 50 frames w/o any flash
issues (it could have gone on for a while after that too). With typical
NiMH's the same case I wouldn't have lasted 10 shots.

My indoor photo shoots generally run around 200 to 400 frames, so I try not to
let myself get into a position where I'm using batteries that aren't fully
charged. Reliability and overall battery life are the factors most important
to me. Last summer I had a speedlight fail to fire at the family portrait
session before the City Manager's inauguration. (I had charged all the
batteries the day before.) I dropped more than $1000 on new equipment after
that fiasco.

Hi

Eneloop batteries are indeed sold fully charged,and they hold their
charge for several years of "shelf life".

I haven't been using my attachment flash much - I prefer studio lighting
(even if I have to lug the SOB's with me). But for that event the
Eneloops kept their promise. When I depend on attachment for something
I carry 3 charged sets of NiMH. I've rarely had to dip to the third
set. (And also carry a pack of alkalines).
