Took us over 100 miles over 2 days to get start-stop working after it had been parked up over lockdown time it seems the ss (2nd battery) is last in the link for charging i find running with the Aircon off helps.

i'm doing around 10 miles a week if i'm lucky. all in one go

no aircon on. in fact only things on is lights on auto and the radio on low

otherwise i'm just going to drive it more like what they said

Pack sandwiches and a flask and have a ride round the Trossachs.
Cannot think of a better way to keep the battery in top condition.

Battery charging rate is not linear, one very long trip will not bring back the Start/Stop. And aircon use has no impact on charging rate. It takes many long trips to charge the main battery over 85% State of Charge.

Start/stop is like a bonus for frequent flyers, not offered for occasional weekend travelers.

Drove from West Yorkshire to Scotland today, stop/start innactive, following lockdown, at start of journey.
Stop/start became active again just after Dumfries about 180 miles into journey.
As previous contributor said more a frequent flyer thing, more use more miles more stop/start is active.
I would be surprised if you have battery problems, they usually appear at start of winter.
Watch and wait, a new battery won't be too costly, try main dealer for quote if you do need a replacement.
