This brand of batteries, as sold by METRO, was already tested here. However, the 12-pack sports a more attractive price — a single cell comes out twice as cheap. Also, the measured capacity here turned out to be higher: 2140 vs 1940 mAh. It seems that you should not count on the repeatability of the characteristics of this brand.

One curious detail: the paper back side has information about the capacity of the cells: 2600 mAh. This is notable, since primary cells rarely have any capacity information.
