I ordered two batteries, but the shop was obvious out of two-packs.

The two cells tracks nicely and capacity drops a bit with load, the 5A test was above the cells abilities.

Thanks for the review HKJ! 

Did the package say something about the cycle life?

Look at the photos, I did not get a package. I found a datasheet, but it did not list anything about cycles.

Got it, thanks HKJ.

I could only see some plastic... so it wasn't clear to me if there was a package inside Smile

The Blue AAAs seem to have only 60% life cycle compared to White AAAs

The Blue AAs seem to have 70% of cycle life compared to the White AAs

I did write Low Self Discharge in the review, but I could not find any specifications what they mean by that.
