Get your battery supplier (or an electrician) to check the battery over,some modern batteries dont last the length of their warranty !

Put an ammeter in series onto the battery when she is switched off and lock the car with boot open (if possible) and see what current it draws. That will tell if you have a leak down. Alarms systems have a certain amount of current draw but 2 days is too soon for a flat. Mine regularly sits for 2 weeks as you know.
Also check the charging voltage with a multimeter.

Hope this helps
