This is the 60 amp hour battery for your car Ben which I have bookmarked for mine when needed. I particularly recommend south Korean brand Hankook having used them in all my cars and also a half dozen large capacity ones in a narrowboat. I've never been let down or had to change one yet and the price is rarely beaten.

Battery Megastore seem to be cheaper than Tanya when delivery included and they offer price matching anyway. If the battery is 11 years old it will be screwed anyway, don't waste time just replace, they are consumables.
