Unfortunately, the battery was despite the stated "100% compatibility" not compatible .. :-( Both the model of my netbook (ZG5), as well as the original battery (UM08A31) are indeed listed in the compatibility list, but nevertheless this was then only invite but not operate ... But money was promptly refunded (incl. Delivery for return postage), and the contact is also very nice. Therefore 1 star would be an understatement ...... Unfortunately, I kind of contact helps only not really, because the price would be top notch if the description would have voted.
Now I have to dig deeper into the wallet and hope for a competitor ....
