I immediately put the batteries provided support since they were (half) discharged. I had another magazine of the same brand and the noise is about the same (do not charge the night in the next room ...). The lights are very convenient to check the state of charge. I forgot to time, but the time seemed quite short, especially compared to my old charger. Good point. For when the loupiots require batteries to play Wii, they must come "on", of course ... And when there is more in the battery tray is the galley. There, it is fast charged. So I'm delighted with this charger. The question is whether the batteries last long. To see in time.
