I had exactly the same fault on my V60 - Stop/Start Service Required but also had issues with reverse sensors. Local dealer said that the main battery was low and that I ideally needed to leave it with them overnight. Not really an option so bought a smart charger from Halfords and left it to charge over a few hours during the day (until it was finished). Not had a warning since. Perchance do you only drive short distances a lot? In my honest opinion, always buy the best you can afford. An extra years warranty for only £54 and Bosch (which are renowned good batteries), sounds like a no brainer.
