Our Gov Vehicle sits for about a week without being driven; when we go to start it the battery is completely dead every time. Nothing is left on and the battery was replaced a few months ago. When the car was taken into the shop they said it was fine. They replaced the battery to see if that would help. NO HELP! Even odder yet is the fact that after it is jumped the battery says it has 3/4th power. We drive it for a few miles turn it off and once again need a jump. Does anyone have any idea what the problem may be and how to fix it. I PLEASE Help
