Sounds like you have a wiring issue. So that is draining your battery. It's called a parasitic draw or drain. If your handy with a multimeter and pulling fuses, go to youtube and search "Parasitic draw"

I didn't know about the youtube thing. I've described the procedure so many times on this site, one can see them on similar threads.
