Like most other customers here, I'm just pissed on the company Ansmann, all described defects have occurred to me as well. The fast charger fully charged and lo and behold, some hours later, things were empty again !!!
For many years, I use the conventional Ansmann batteries and am still convinced of the quality, but these fast-charge batteries (apparently of a subsidiary?) Are the total surplus in the oven and if not soon what is being done through well known customers it ...
