095 pretty sure, but have a measure up, and do research about on carbatteryshop.co.uk etc.
99% of fords will take three different batteries sizes on the battery tray, the obvious bigger capacity ones would be diesel variants of that shell/body.
But if looking for max performance it would be a AGM, but around £150, the Varta Blue Dynamic is a ace value/performance way above std fitment, that's what I use.
