Land Rover Repair: Battery Drain, battery drain, land rovers

Question
Hi, Im really confused.. Ive replaced my Land Rovers battery twice now and for
some odd reason, the battery drains... Im thinking of just taking it in for repair
but since im a female, i dont want to be taken advantage of. Would you please
give me some possible reasons why this might be happening?  

Answer
The battery is getting drained because something that should go off, is staying on.  Finding drains can be time consuming.  There is not much I can say to prepare you as there is no "common fix" for this problem.  Could be an alternator, a body module, another control unit, even the radio
