Ford Focus equivalents

I imagine that the ecu compensates as time goes on, it just needs to know when it is changed and the spec. it has, just like some cars now need to be told that they have new brake pads and how deep the material is, after that they are fine.

Not sure of the current labour rates at a main dealer, but 150 quid an hour won't be far out. And as soon as they have to hook it up to the computer (which takes seconds) you'll be in for a more than an hour's labour. Because computers speed up and make servicing simple, it's said. And that's after charging you twice as much for the same battery as you could find it elsewhere.

I've had mine nearly 3 years, and I'm very happy with it. When I told my daughter I might buy a new car in February, she asked for first refusal on mine. ;) She has driven it, owns a Fiesta, but likes the easier ride in the Focus, and the larger boot.

Then I see no reason why it can't learn a new battery on the 'fly'.

Then you should become a programmer for BMW and others.

I already do embedded programming but for an alternative employer!

There probably isn't a reason why they couldn't.

Plenty of reason why they don't.
