Assuming the URL I sent shows the same one you have

It is.

, why the lithium battery?

- Shelf life?

Yes. I consider this very important

- More burn time than the 8-hour burn time they tout for a AA alkaline?

Maybe - though I don't know if it does last longer. After several years in the
unit, it will last longer as the alkaline will have self-discharged to a greater
extent.

Also:

Better performance at low temperature - important in cold air or water.

These aren't fancy lithium batteries - just the 1.5V AA version sold usually in
photo shops (conventional lithium are usually 3.6V or so).

This strobe has a catalytic mesh in the bottom of the unit, so any gases (H2?)
produced by the battery over time tend to be converted to relatively inert
compounds. I still don't know if it's important (since the volume in the strobe
is so low), but it's there.
