George,
I don't know why you posted this in the X150 Forum, as it pertains to the X351 XJ with Stop-Start.

My 2013 XJ has the first version of Stop-Start with the small auxiliary battery. My CTEK MUS4.3 works perfectly to keep both batteries fully charged. I use two separate pigtails, one for each battery, and alternate attaching the CTEK between them. Here's the Stop-Start pigtails with alligator clips.



I can't address using a CTEK with the later capacitor-based Stop-Start system.

A Moderator should move this to the X351 Forum.

 

I'm sorry, but what was the question?

 

Perhaps least useful post ever. Subject doesn't give a clue what it is about, neither does text. Seems to be all about bashing UK forum, and then it has nothing to do with X150s.

I have their Bosch AGM battery in my 2013 XJ and am very pleased with it. I'm not sure if you need an AGM battery because your 2012 XJ doesn't have Stop-Start. Put the same type in that came from the factory.
