In general I recommend to get the battery replaced after 10 years.
You can easily identify its age, as a date can be found on the minus pole of the original BMW batteries (mm/yy, 07/09 is from july 2009).
All good again today. Roof worked beautifully, although I had an "excess battery drain" warning pop ups this morning so looking more and more likely to be the culprit
