White Battery symbol in Dashboard Display - 2008 ML350
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 ?

Yes, I did reset error codes using OBD2 scanner. I do not think there was any code related to battery though. I do not think low battery shows any specific Error code.
- Turn key to acc position (do ot turn vehicle on)
- Cycle through dash menu so that you have the odometer display on
- Hit the R button three times quickly
You will see the battery voltage level on dash. 12V is good
Turn vehicle on and a few moments later the voltage reading will change to 13.8V. That means the alternator is doing it's job.
