Fenix ARB-L2 18650 battery

[AhaAha]

Hey guys,

any thoughts on this battery? A store around the corner happened to carry those when I really neded a new battery and I guess I just want to make sure, that I'm not terribly wrong with them in my Zmax and my nitecore i2 charger. The battery life was pretty impressive so far.
