Hi All. I read the forum nearly every day as part of a 70+ year old non mechanic trying to understand these modern motors. My question regards the renewing of the battery on my C5 Tourer. I have read and printed the recommended disconnect/connect procedure however my local tyre/battery man maintains that plugging a battery into the 12v socket in the load area is sufficient to maintain "battery presence" during the changing of battery and makes the recommended procedure unnecessary.
Is this correct please.

I can see this working PROVIDING the 12v socket is permanently live and does not switch off with the ignition.
The one caveat I can see is that care must be taken not to draw too much current through the socket otherwise you run the risk of blowing a fuse.

As said above as long as the socket it permanent 12v then absolutely ok to do this.
I have a similar tool only it plugs into the OBD socket, much more useful as many cars dont have an always live 12v power socket now.
Again as said above they have very small fuses in them so would still wait 3 minutes after ignition off before disconnecting the battery so there is very little current draw.
