Dang, you’re cornering the AA market with about every possible flavor/chemistry.
What will be next: nuclear AA batteries ? 
EDIT: thanks @zoulas for pointing it… I missed these XTARs are non-rechargeable, so they’re about the same as the age-old Energizer Lithium ultimates that we can already get basically everywhere… so nothing incredible in the end.
I don’t see them for sale anywhere yet here in the States
How do these differ from Energizer Lithium that have been around for the past twenty years.
oh man… I was going to reply to you, “but these are rechargeable!” and then went back and noticed that’s exactly what they’re not. Totally missed it when reading it through the first time… 
Correcting my other post above…
Awesome video!
