The batteries need some charging cycles to reach full capacity. In this they are the more expensive brand name batteries after a few tens of charging cycles in nothing. To this end, full marks. For this, however, you need a suitable charger (I use this one Pixo). The supplied battery charger is not suitable for the intended intended purpose. The idea is good to use a base unit for different battery types and these types of batteries then adjust a Adaper. A charging electronics, which control LED lights up permanently, whether a battery is charged or not and not abeschaltet, is nonsense. I kept it for the USB adapter anyway, for it 1 star.
