12v battery replacement? 2024 Coupe

Hi all, new to an Enyaq Coupe, not new to the forum or Skodas in general.....

I've just bought a 2024 vRS coupe. I went to fit my dash cam to it and found a hardwire nextbase kit already fitted - result! Unfortunately, the fuse used was a permanent 12v live (!). I've since moved it to a switched 12v. I've been having app 'no connection' and 'battery protection' statuses.

Historically, my Superb L&K from 2014 had a dash cam running from the 12v socket, which, ultimately meant the start/stop 12v battery required replacement.

I'm wondering if the fact that the dash cam in my new car was connected to a permanent 12v has caused the battery to fail prematurely.

I think it's worth changing the 12v battery to a new one to see if it sorts the app status issues. Has anyone changed the 12v battery? Anything to look out for?

Cheers

S
