Battery CEL - Artefact of Disconnecting Battery?

The CTEK charger fully recharges my battery no problem. BimmerLink reports it as 98% after a day or two. ?‍

Try using a load tester on it and see what it says. Everyone should have one in their tool kit these days with battery condition being so critical to the modern cars electronics. About $60 aud or there abouts on Amazon or Fleabay

Agreed. Sometimes, only a load tester will reveal the true nature of an ailing battery. Have seen this once with my own eyes, but I bought a tester right then and there on my phone. One time was enough.
