Inside the envelope the cells was only wrapped in a piece of paper.
This battery has a high voltage at low loads.
Conclusion
This battery uses a Sanyo cell, this is a good quality cell and as can be see on the curves the two cells does track very nicely. There will be no problem with series applications of this cell. The high voltage can be an advantage in smaller (i.e. 3-4 watt) lights where the battery replaces two CR123 cells.
The PCB current limit is placed about 30% above the cell specification, this is a good value.
All in all a very good battery.
That is related to the chemistry in the cell and Sanyo has obvious found a great formula for this cell. I would guess that it is related to the high voltage and the sharp drop at the end, where many other batteries drops more smoothly and are below 2.8 volt, before they are empty.
I must say that your battery reviews are always very good. Condensed information and great visual help to understand cell performance. Thank your very much for taking the time to do both the test but also the write up and publishing of this. I´ve used your site many times over the past 3 years and never felt like there was something missing.

I don't think that is uncommon. Even if you drop the voltage from 3.0V to 2.8V (say at 1A) it also does not vary much at all. I have experienced that with some cells before. Sanyo cells traditionally have a very good and usable knee, good for some types of lights and maintains good brightness (related to voltage under load) till cut off.
Already mentioned quite a lot of times, just go for the XTARs. Numerically, it might just test to about 2300mAh on the charger, but it's a different story out there. (I tested various cells including the XTARs in the SR3800 triple XM-L with LVC many many times. The XTAR's good)
Sure, the XTAR's are good cells, only problem is I cant fit them in my most used lights. They are to fat. Without the sticker they fit some of the lights but it's tight. Such a shame.

Really? I have several XTAR's 1800, 2200, 2400, 2600 and i had to even wrap them with electrician tape occasionally to not rattle inside L2 clones and similar. On one uniquefire l2 the fit is almost perfect perhaps a bit tight as i have to tap the battery out sometimes (if the flashlight is freezing cold).
