Portable Car Odometer Is A Dead Battery On A New Car That Hasn't Been Used Normal?

Is a dead battery on a new car that hasn't been used normal? - portable car odometer

I went to a Honda dealer for a CR-V to check the other day. I tried to open the tailgate, but could not because, as the seller was, the battery is empty. He explained that the car had been sitting in the showroom during the month will be started without the battery and lost the juice. She brought car chargers connected a laptop to the battery and everything seems to work, came to light, car started, open the back door, etc.

The car is new, but the '07 and '08 is not new, so I think I was sitting in the showroom for some time, probably more than a month, she said. However, there is a new car with only 34 miles on the odometer.

Is this normal for a number of new car lost power after several months of inactivity? Is it possible that someone uses a port for loading feed a cell phone or laptop, and draining the battery? The battery is defective or is indicative of a broader problem of power?
