Thanks Fire Angel! I think my aa charger is old and stupid (like me). I got some new d-li109 batteries to add to my collection. Might retry the aa some day, with new batteries and a smart charger.
If my experience is anything to go by this is a good idea. I get far more images out of a set of AA batteries than I do out of a D-Li109, usually at least twice as many. If it's cold the difference is less, but even then the AA batteries give me far more images before requiring a change. This makes sense looking at the numbers too, since the D-Li109 has a capacity of 1050mAh, while all of my AA batteries have capacities over 2400mAh each, and you're putting four of them into the camera. The better voltage depletion curve of the Lithium battery helps it perform better than the simple capacity numbers would suggest, but it's still easily beaten by good AAs.

The key though, is making sure they are good batteries and that they are charged in a good charger; most of the chargers on the market are very poor at getting the best out of batteries and the battery makers want it to stay that way. They would much rather sell you a new set after 100-250 charges than wait until those batteries have seen 500-1500 charges...

You can only count a single aa battery capacity since they are in series. But 2400 mah vs 1050 mah is significant.
