He became the battery itself, ordered for the Medion Akoya p6812 (MD 98760). The original battery has kept Almost 3 years actually, despite high loads. Respect to the Fa. Medion it. The replacement battery is black in color, fits absolutely accurately in the notebook. For power I can currently say anything, come with 69% state of charge (4,5 hours useful life). More powerful than the original it should be. I'll try that when I'm charging the battery properly. Then I certainly hope that he does what Tradeshop promised. ;-)
Charging time completely => 2,5 hours
