mac power pro battery did need charging; something in the car must have drained it fast in a week

I got the troublesome car battery back from the battery place, where they charged it overnight and tested it today. Seems it's ok and doesn't need replacing. So I put it in the car and the car does start. So what was it that drained it so quickly before? Could it be the electronic digits on the radio, or the clock on the console? That really was very fast; I don't remember the previous battery being completely dead after just a week and a half of the car standing without being driven. Oh well, seems it will start next time I need it to anyway. I'll just keep the battery disconnected when I don't plan on taking any trips for a few days.
