It does not seem to run as long on the charge as the OEM but it is more than sufficient for the 2-3 hours I require battery. I have never run it to a full drain but in watch the meter it seems a little short.
I would recommend this to a friend

Battery lasts as long or longer than original
My laptop was made portable again, and it lasted many hours of movie watching when power was out during hurricane sandy.
