Did Anyone Ever Find a Solution To This?

My dead battery issue has been an on going problem since I bought the car 2 years ago. The battery and charging system has been checked twice, and all check out. It can go months without an issue, then all of a sudden I try to start it and its dead. I've checked everything I can think of to make sure there's nothing left on upon leaving my car to no avail. I've been finding my car dead more often then not lately, meaning it seems to be getting worse. [solo] I have the same problem Did anyone ever find a solution to this?
