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 other obvious difference is the country of manufacture: the ones here are made in China, whereas the previous ones were from Indonesia.

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.
