First of all I must say that I have the shop where I ordered, selected by the reviews. That was not my worst idea. The delivery went very fast and the battery is also the one I had ordered (is probably not the case everywhere). My laptop has the part also recognized and is hard at work to charge the battery. To the capacity or the maturity I can here and now write anything yet, but has so perfectly as from ordering works So far everything is the battery probably also keep what was promised. The shop you have to recommend!
