I thought at first to a mistake on my part, however, the batteries behaved even two other trials as well. These batteries are completely empty after a few days, even if they are not used. I know that NiMH batteries have a higher self-discharge, as "conventional" batteries. But these batteries have really shocked me, especially because even my age-old batteries are still far better.
If that really is supposed to be "normal" that these batteries is virtually completely self-discharged within a few days, then an appropriate warning on the package should be at least (and in particular on the Amazon website at the technical details!) Be present.
