5 out of 5 eggsseems to be better than expected

Pros: Fits very well into a unique space on the D620. While rated at 4700ish IIRC it is actually the same 5800 whr battery as the stock one. I've just run a batch of windows updates, installed explorer 9 it has been doing all this thru wi-fi and at 1.5 hours in it still shows over an hour of battery life left. No bad for this once state of the art business laptop that still runs very well.

Cons: I can only think of one thing, price, but then who does not want stuff for less!
one more nit, you have to jiggle the battery just a bit to get the second latch to hold. This does mean the battery is tight once latche so its a draw!

Other Thoughts: I'm amazed at how well this battery seems to hold up to use. All I expected was something to keep it booted up when I have to unplug and move through the building. This is doing way better than that!
