Delivery very fast. Original battery very well, holds approximately 4 hours. Actually, I have always ordered original batteries, with whom I was very satisfied. Due to some customer reviews I had the last time an alternate battery, which also good reviews received, but only 1/3 cost gakauft. After 4 weeks, the charge capacity held only about 2 hours. After 6 months, then was quite final. Therefore, back to the originals and never substitute.
