All devices from the chargers, finally holds no battery on a break of 3 months. All devices flash red, are thus charged. Only that after about 5 minutes all devices began rapidly blinking red. This rapid red flashing means 'Error loading', thus defective battery or other problems. Equipment put right something that display red again. So about five times, then the first device has begun reasonable to load and was eventually teal. On the second unit it worked for about the tenth time in the controllers 3 and 4, it has more than 20 trials (I was already trying to dig out the bill and to bring the charger back to the store) used until the charging cycle went through. After a dinner break I have again put the controller in the charging stations, where they have uploaded a few hours again. Now all battery packs are charged reasonable.
The problem is probably that the batteries have fully discharged by the long break is. I will make in the future the battery packs each month in the charging station to work around the problem, but really happy I'm not so. Here, the charging station should be improved because a longer summer break may occur from time to time.
If anyone gets the problem: not give up easily, I have launched a Tag 'Controller wobbling' behind me, until all were working again ...
