if I did not know any better you would think that it is original goods from Dell. As the previous speaker writes it is indistinguishable from the original, even the capacity display of Dell is included. The battery also keeps just as long or short (as you want) as the old battery (full charge approx 90 min.) Stop is a problem from the Inspirion draws so much current, at least I do not know it differently since I have the laptop. Otherwise, I can only say so far for this price, the battery is absolutely unbeatable. For a detailed review, for example, long-term study of course I can not say anything but it makes a very good first so as I said original goods impression.
