R digital cameras that run on rechargeable AA batteries better than those running on a lithium ion battery?

The easy availability of double AAs is a very good advantage. I remember in studio class having my main and backup batteries dying, but since my camera could take any old AAs, I just rushed to a nearby store and was able to finish my assignment.

Lithium ion batteries definitely pack more punch and you'll probably need to recharge less, but they're all custom built and hard to replace.

The lithium ion battery on my nikon lasts an incredible amount of time.

Those are the pros and cons.

no

You can use both rechargeable AAs AND Lithium in most cameras. I use both in mine. I have Nikon CoolPix 7600 and love it. The Lithium batteries last a really long time.

nope

i would not say better defiantly more practical AA batteries are cheap you can afford to Cary a fue backups with you

Lith-ion is an improvement over ni-cads. They are not as prode to deep memory charging problems and they last longer.

AA batteries are cheap and readily available thats why I like them as I can have backup, although they don't last as long as the lithium ion batteries.
