The battery in the S7 has been on its way out for some time now, fitted about 8 year or more and with the car being laid up in the garage for the last few week it has now been killed off for good.
So before Mr Brown sticks the VAT back up on everything I gone out and got a new one.
The new battery is for a 1999 2.0Ltr Ford Focus, so it should be up to powering the S7.
