The most likely culprit for battery drain is a short circuit in the system. In my experience, new stereo installations or short circuited lights are the the most likely source. Try going out to the vehicle after dark and see if there is a light under the dash board or if there is power being supplied to the stereo. If that does not prove fruitful, you may have to have the fuse panel screened by a qualified service technician to determine if there is power being supplied to a curcuit that is not designed to be powered after the ignition is switched off. If you had any new equipment added to your vehicle recently, I would start there.

Battery light followed by total failure on freeway. Autozone tested altenator and replaced battery earlier that day.

change alternator and maybe battery. Since the battery is pretty new, draining it like you say only took a year or two off its lifespan. Remember how your car acted this time, as most newer cars do the same exact thing when the charging system or battery needs service. In the future, you will recognize the symptom and know where to look before you get stranded.

So i have a Mercury CApris 91, i just replaced the alternator and battery and the battery still will not keep charge the charge will last about 1 day and then day ..and the only way to start it up is...

If you replaced both the alternator and battery and the car starts, if even only for a day, then it has to be the wiring from the alternator to the battery. Thats the only other thing I can think of. Check that or just replace the line and let me know how it goes.

Battery & alternator test good. Battery runs

from the sounds of it ?? could be the altenator ,a diode is allowing the current to run to earth,disconnect battery when not using the vehicle ,if it starts ok after having the battery disconnected then make sure a boot (trunk) light isnt staying or something stupid like the abs pump or suspension leveling`pump if fitted .But the altenator is the most common problem

Sounds like the alternator may be missing an excitation current source.
Check the 'IGN' dash indicator lights when you turn ignition switch on prior to starting motor,
if not one of the below may be problem:-
1) check exiter control wire is connected to alternator D+ terminal (low current wire, +V with Ign on),
2) replace dash 'IGN' indicator lamp.
