Super Charger + Batteries

On the recommendation of colleagues I have recently ordered me Eneloop batteries and the appropriate power supply. The charging times are even less than the manufacturer with this charger and new battery. The charger provides operation LEDs which look / shine specify the status of the battery through her. The charger signaled with some of my older Ansmann batteries a defect, which I had previously suspected, but never found out which batteries were exactly affected. The batteries are to be with me at the time in a variety of devices in use and have not yet been empty for an assessment at runtime.
