My DB9 date of first registration is 1rst May 2005.

Since owning the car it has always started on first push of the start button and at this time the battery appears to be fine.

On checking the service history and bills from previous AM dealerships however , it seems the battery is the original.

This being the case I do wonder how much longer it can carry on.

A casual enquiry at my local AM dealership as to the cost of supply and fitting a new battery resulted in a quote of £374 .

Anyone on here fitted a new battery ? If so does the CPU need part re-programming after fitment ? Anyone know the Cold Crank Rating for a DB9 battery ?

What I am trying to establish is this.

1.When the battery is disconnected, and another reconnected, do any of the on board computer systems need re-flashing ?

2.What is the cold cranking amps requirement for a DB9 battery ?
