evening chaps.

can anyone recommended a make of battery for my 500C?

Try the Batterymegastore. Com good and cheap but also look for offer codes on Eurocarparts and Carparts4less
Whatever one you get check the physical size with respect to your tray size
This one may fit; http://www.batterymegastore.co.uk/varta-d53.html

Or this for £89 after discount code; http://www.carparts4less.co.uk/cp4l...2426d3271ccabe5a3a97db8b69520969a48708&000020

Thanks john2020 - I got my battery for my Jag from megastore - good service.

...and if you have stop-start make sure it's a SS compatible battery!
