I turn off all my switches fan,lights,fuel pump, radio, nothing else is on. I left to go out of town for a week and came back and it was dead. I killed my red top I charged it and put it back in there. I can drive the car around for 15-20mins shut it off and try to start it and it acts like it has no juice. I had the alt. checked out it was good I put this battery in my mud truck and its fine. Oh yeah the battery is in the trunk if that matters any I dont think so.
