Why did you replace the battery? Why did you replace the alternator? Is the battery saver light on and the Battery light on? Or is it one or the other?

Battery saver has to do with the lighting system. It will turn off lights that are on after you shut off the key. Is this light on while you are driving?

battery light tells you that the battery is not getting charged. Have you checked the battery voltage while the vehicle is running? What voltage reading do you get?

The charging system is controlled by computer. You should have the vehicle scanned to see if there are codes stored for charging. Also the scanner can see what the alternator is doing and how the computer is trying to handle the problem. If the computer is sending the signal to the alternator and if the alternator is responding to the signal. If the computer is sending the signal out but the alternator is not charging you have to verify the signal at the alternator. If the computer signal is at the alternator then it may be time to check the warranty on the alternator. If the signal is not there at the alternator connector then you have to check if there is a broken connection between the computer and the alternator connector. (brown and gray wire at the alternator is the field control wire} You should also make sure the alternator has a good ground.
