Ey everyone I have a 03 cobra, just put a new battery in it and if the car sits more then 4-5 days the battery is COMPLETELY DEAD! I know it's not a crap battery because I have a snap on battery tester and after charging it fully it shows it's fully charged, but as soon as it sits for 4/5 days It won't even turn over, any suggestions on what's draining it or how to trace the problem?
FYI everything is complete stock including radio and there's no lights left on or nothing plugged in
Thanks
