Hi Allan,
I have exactly the same problem but with an easy solution. We have two cars!
My Jaguar s type diesel is now sitting on the drive and gets the battery charged every 5 days, and my wife's Toyota Yaris Hybrid is going a great job. Without it I would be stymied as my S type needs about 40 minutes driving a week to keep the battery and car operating properly.
Let us use hope that matters are sorted soon.
Regards,
Peter.
