Sorry to break it to you but the service you took your car is bunch of clowns! There is no DTC for support battery.
They need to check the (start/stop) rejections which are recorded under CEM. I had the same issue, although the support battery showed fully charged, the engine would not stop and start on traffic light. Not that I like the feature and use it at all, the car was under warranty, I just wanted them to fix it. They ended up replacing the battery.
