The battery was packaged well, the part itself nor specially eingeschweißt.Es looks almost exactly like the original, only the labeled that.
The performance - 1600mAh is the same as the original battery. Also the charger is 100% compatible. The battery was charged very quickly, could be used without problems in the Camera (Sony SLT-A58) and was ready to use.
I am convinced of the article and would not hesitate to order it again. 5 stars for it.
