AA battery life
Just a bit of a rant. :( I have an SLR camera that I use a lot, mostly for documenting restoration of 2 cars I've been working on for a while. I use ordinary AA batteries and not rechargeable one...

Tom is more correct than I was. The actual numbers for LiFeS2 are 1.8 volts.
I found their life span poor and not cost competitive with alkaline AA and AAA from dollar stores.
Tom thank you for the correction and for getting me off my duff to research this.

redracer,
The AA li have to have a voltage dropping resistor. I'm not at all happy with them.
The nominal voltage of lithium-ion is 3.60V/cell.
There are rechargeable AA and AAA cells which have a buck converter built into each cell.
A dropping resistor will not work. Half of the energy would be wasted in heat and you would get huge voltage swings depending on the amount of current drawn.
