It came quickly, fits like a Dell part and charged properly. I don't know what the full charge life would be for a Dell part but I seem to get 3 to 5 hours from it depending on how much graphics I'm doing. It's running Ubuntu Linux so that may reduce the load a little and extend the charge life.
Good value, works well
