Re: Battery Management

Those are lithium batteries, CRV3s. As someone mentioned, lithiums 
have an extremely long shelf life, up to 10 years. I haven't used the 
ones that came with my D either though I've used one set of the 
Lithium AAs with this camera. Of course, now I'm not sure where they 
are! The only real drawbacks to Lithiums are the expense and the fact 
that they can be a little hard to get out in the field. The AAs, at 
least, are probably cheaper per shot than any other disposables. They 
don't stop in the cold, either.

Thanks to all who replied - looks like I should fire up the charger!
I still have the original batteries that camera with the *ist-D, 
which I suppose are lithium.  there are just 2 batteries, each on 
filling two AA slots.  Those are my backups - though I should 
probably use them before they get too old and put some lithiums in 
the bag as a backup.

I usually just charge whatever I can and not worry about the fine 
points. Don't use a flash. switch to lithiums. Lately, I've been 
having batteries quit on me that I thought were charged, which is a 
nuisance even if you tend to carry a lot of batteries. I made one 
interesting discovery due to this recently though. All of my 
rechargeables had pooped out on me so I went looking for some 
disposables so I could keep shooting. I generally get the lithium 
AAs which really last pretty well. this time all I could find were 
alkalines so I got the fanciest ones they had (why not?) and was 
pleasantly surprised when I got around 150 shots out of them. I'm 
wondering if the istD has the low voltage cutout situation you here 
about with some other cameras.
