Is Rover or battery maker Delphi responsible for battery failure after nine years?

Does this win the prize for the most optimistic claim for product failure? Last week my dealer-maintained Rover 75's original manufacturer-fitted battery failed after barely nine and a half years. Is Rover or battery-maker Delphi responsible?

No, there have been more optimistic claims, but none yet against a manufacturer that went out of business more than six years ago.

A fine looking car from all angles, until the 2004 facelift. Destined to become a 'classic'. 2.0 diesels proving to be good long life cars with excellent clubs and spares back-up. Up to 4 stars.
