Changing main battery and small battery reference

Are there any problems changing the main battery on a 2015 A207. The reason I ask is that on Jaguar XFs between 2012 and 2016 disconnecting the main battery can cause central locking plus other things to stop working. Jaguar issued a Technical Service Bulletin on this and their solution is to change two programmable junction (fuse) boxes and reprogram them......at a cost in excess of £1,500!......garages with Autologic diagnostic software can reprogram them and charge £100 maximum. Hence wanting to be sure that there can be no nasty surprises disconnecting the MB battery.

Also what is the secondary stop start battery reference?

Many thanks for that, no mention of a slave battery so should be OK.
