Thank you so much for the quick and good answer. Just to clarify, the Panasonic NCR18650B is the original battery that comes with the Air 2? I have found it on a reseller, thanks a lot.
No, NCR18650B is the CELL used in Air II. I was serious, "battery" is incorrect (although very common).
Stick with genuine NCR18650Bs (from Panasonic) and you should be fine. Even if you and everyone else you know incorrectly thinks it's 'a battery'.

One is a cell. A stack of cells (two or more) is a battery.
You're welcome, of course, glad to help when I can.
Best wishes.
