The battery is certainly compatible, but after 2 times will charge a stepped protrusion on both internally and externally. A sort of "swell" thus the battery was also hard to see. Returning --- with simultaneous order of an identical, new battery. However, here was a different material properties in the area of "extra bar" for the first. The coating acts rubbery and sticky. Beginning when unpacking "fuzzy" The fit in the PC was clearly better. Because there is this material nature in the upper, visible and work area, the immediate delivery of returning. Vielleicht- to the other very positive reviews, and the reason to buy for me, I had unfortunately caught 2 "Monday models". Star is only available for the service of Amazon and the speedy refund.
