Most common is a bad alternator, it may check good but if the diodes are bad it can pull out power as well as make it. Computer controlled charging systems make it difficult for most parts stores cause they can’t check it right, so find a good independent shop that knows how to check the entire system. Won’t be the first time a computer has caused a battery drain problem.

You have a serious power drain , I guess the good part is being so bad it could be easier to find
