This is the second Sony-branded pack tested here. Previously tested were a 4-pack, labeled „Sony Stamina PLUS“, which was both quite more expensive per cell, and had lower capacity, too (1980 mAh).

The difference becomes even more clear when the two discharge curves are overlaid in one chart:


It seems then that we're dealing with two completely different sets of batteries, which share the same brand.
