I'm having a difficult time following your post. Maybe you should try breaking it into multiple sentences. it seems you are having issues that would point to a bad battery, but the battery was replaced. I would check the voltage to see if there are no issues with the alternator or problems with a voltage drain. You should have 12.6v at rest, no less than 11v during cranking, and 14v at idle.
