Same thing happened to me a couple of weeks ago with my 9-5 and I had to buy a new battery. Apparently if a car's battery's voltage falls below a certain level for a certain length of time it never really recovers. Having got the car going I drove it for about 60 miles assuming that would charge it up. But when I got in the car the next morning it wouldn't start.
