At the same time I have but still ordered two new controllers that however only arrived a few days after the Charger so that the battery charger was initially equipped only with the two old controllers.
We have the new controller unpacked, unplayed provided with the batteries and also placed in the charging station. After only two hours the device indicated that the batteries are fully charged (provided for charging the early afternoon).
In the evening we sat down then Four of the Wii, but the disappointment was great. The two most recently loaded remotes did not stop by, the empty one not even 10 minutes, the other was after half an hour. Instead Fun's been frustration! Our old controller had, however, after four hours is still more than half of its current capacity.
We thought at first that the first charge may not have worked and have a day drangehängt. But even now, after four days of use especially like a battery only maxmal hold half an hour. This is not a convincing result.
Conclusion: Since we do not know why this might be, individual batteries for this station also are not available, we will send the unit back now and instead "normal" batteries with 'normal' buy charging stations.
