The car had to be taken in. Apparently there's some switch in the software that says when you get a new battery you must reset it (somewhere) or it’ll (aux battery/alternator?) send more juice to the battery causing it to overcharge it and therefore shorten the life of the battery or out right cause damage to it.

Bottom Line is that it is not straightforward anymore. I could find this nugget anywhere online. I wonder if people know this? Anyways just an FYI. Still have the other things to do. ��
