My car has 157 miles.
My car has an automatic transmission.
You state the battery does not have a parasitic drain on it but battery is dead in a few hours tells me the battery cannot hold a charge. Have the battery load tested to see if it is able to hold the specified load and still start the car. If not replace the battery and check charging system.
