The "repair" held exactly one mowing. Now the charger generates no loop signal, pretends to be dead despite the current actually gets there. Presumably, now has some thing given up the ghost in the charging station.
I would like to stress that the mower in the winter is naturally in warm and dry and the charging station is covered.
From my perspective, it is a completely immature product. We would definitely not buy Automower from Husqvarna more!
