The batteries per se: they are priced, apart from a few exceptions from, a bit cheaper than brand batteries, therefore, that move in midfield. From a performance point it looks similar to: significantly better than those from the discounters, but maybe not quite compare with the top products.

Likewise there is no information on the ingredients; but their absence on other AAA batteries, which I have here still around. They were made in China.
Conclusion: on the package you could have saved something. From the price-performance ratio here they are perfectly fine. Who will soon provide its remote controls or because of me his mp3 player with new batteries, is not with these ill-advised here ...
