Safe Discharge Rate of Alkaline Batteries
Getting detailed data on capacity, safe discharge rates, life span and voltage discharge characteristics for most batteries from data sheets is nearly impossible. It seems as all the main stream alkaline battery manufacturers data sheets are little more than glossy marketing brochures with pretty colored pictures with extremely little hard data.

One wonders if they do this intentionally to keep customers from gaining expectations over battery performance that cannot be consistently met by the products. 

Note that it has been my experience that you can get better data if you work directly with the manufacturer. I had previous experience with designing an NiMH battery pack with AAA cells. The industrial division of Panasonic was very helpful at the time of providing test data on their cells.
