Customer Question

Okay looks like you have a parasitic draw on the battery , meaning something is staying on when the car is switched off .

Most common drain on battery's are aftermarket radio or other electrical add on's.

Doors not closing fully or bad door switch leaving inner lights on and draining the battery .

If the alternator was replaced because it was not charging then check the battery ,your battery may not be holding a charge

and draining itself over a few hrs from internal battery damage ..

Here is a good link to show you how to check yourself for a battery drain.
