I have seen tests where the Li3 gets 8 hours of A/C usage, but it all depends on conditions.

Watt-hours are what counts, IMO. And that has to be usable watt-hours not just rated battery watt-hours before the safety cushions are added. Comparing other ways that vary, like conditions just encourages the misrepresentations by the sellers.
Obviously, the conditions make a difference, and that is exactly why stating running hours is a very poor comparison of battery designs. Heck if it is cool enough out, I can run the AC off a tiny battery because it is never on, as a gross exaggeration.
