If it's only 9 months old, take it back to be checked. It ought to be under warranty.
Yes, i`ve checked that voltage is 15 Voltes on battery contacts that means generator works fine, and replaced battery by warranty in PepShop Boys shop, where it has been bought originally.
The only problem is that the $55 labor to replace battery is not under warranty.
The failed battery is a Boshe battery.
