I am thinking of replacing the battery on my C5 as I have no idea if it is not the original one or just a dodgy replacement as the economy mode kicks in a few seconds after the engine has cut off.
I don't think it is the alternator as it has been like this for a while and never let me down.
I am not very experienced in swapping batteries as the only time I needed to do it on my old Fiesta it was still rocking the original Motorkraft one. It lasted a shocking 8,5 years.

Annoyingly enough, the moment I've removed the battery and placed the new one the security for the radio kicked in and requested a code.
Now I think that you guys can give me some pointers on this task and how to do it (I have no shame in asking such a basic question
