I have also charged the battery overnight and it took a full charge, but it still had issues starting after I did that. I think it is not the battery since it starts fine in the morning and maybe it is the alternator? Any suggestions?

TIA

How old is the battery?
Check the battery voltage without the motor running.

Next time you start the car when it is warm, make sure the Air Conditioning is turned off before you turn the key... what happens?
