Energizer L91BP-8 AA Lithium 8-pack Batteries

Pros: @ 2000+ Hi-res flash photos, and a year in the camera, they have already way out lasted any other AA's I have used in my camera, and they still have a full charge. I normally get up to 200 photos.

Cons: None.

Other Thoughts: Well worth the extra cost for the devices they are intended for (SLR cameras being one).

Pros: Great shelf life. More power than Alkaline or other formulations.

Cons: Expensive!

Other Thoughts: These batteries are great for storing away. Lithium batteries have excellent shelf life and cold-weather performance. They will last for 10 years sitting in a drawer with minimal self-discharge. I use them for the flashlight I keep in the car and anything that needs more power than usual such as cameras.

Pros: Stuff works with these batteries.

Cons: Nada

Other Thoughts: I don't know what happened, but I bought these batteries assuming they were rechargeable. Boy was I in for a surprise when I put them in the 15 minute charger
