Battery goes dead after 3-4 days.

My 2008 CX 7s battery looses about 2 volts everyday that its not in use. Of course after 3-4 days it has dropped down enough that it wont turn over without jumping or charging it first. I have replaced battery with 2 new ones so I assume thats not the problem. Anyone have this issue and resolved it before?

You'll have to test for a parasitic drain. Here's a VIDEO TUTORIAL on how to do this.
