White Battery symbol in Dashboard Display - 2008 ML350

Hi,
I am getting White Battery symbol in Dashboard Display after accidentally leaving door open overnight which drained my battery out. I had to jump the car to start. After that I charged main battery for 12 hours using my battery charger still I saw same Icon. Thinking Auxilary battery is bad, I replaced Brand New Aux. battery and still same issue. I went to Advanced Auto part and got main battery tested and they said your main battery is fine.

What else could be wrong ? Can someone please tell me White Battery Symbol sign is for Aux. Battery or it could be main battery ?. Do you think if I wait couple of days it will go away because alternator will charge battery after some use of car ?

My car is 2008 ML 350

White warning is for the Aux battery, red is main battery. It could be other issues causing it to think the aux battery is weak, wiring, other modules interfering. Check the voltage of the new battery, verify the terminals are hooked up correctly. Otherwise a star scan is in order to see what it thinks is wrong.
