Send it back.

If it doesn't show up there is something wrong with the controller in the battery (assuming your old battery did show up and charged). There is a circuit that controls the battery and will shut it down if it overheats or the controller senses the batteries have a short. Either way I would not bother troubleshooting something that is brand new with a warrenty and shows up DOA, nor would I start monkying around with shorting it out which will show up when you send it back for warrenty replacement.
