981 - does 12v socket stay 'on' even if accessory turned off?

I cannot leave my car plugged into a CTEK all the time. But, when I need to unplug from the mains socket I tend to just unplug from the mains & leave it plugged into the 12v lighter socket near the armrest.

Does the socket stay 'live' at all? I cannot think that it is drawing any power but have had a couple instances now where the car says 'low power, drive for an extended period' and wondering if it's because it's had something plugged into the 12v socket, even though not hooked up to the mains.

For reference, battery was replaced 12 months ago & coded to the car via a reputable specialist. Car is a 981 CGTS
 
Hi,

I’m not sure if this helps but there seem to be mixed experiences on various forums here on whether or not the power socket remains live, especially when a battery conditioner is connected. It would appear that the socket remains live if an accessory is connected when the ignition is turned-off … and maybe also remains live for several minutes even if nothing is connected, allowing some time to connect and power-up the battery conditioner?🤔

Definitely mixed experiences. On my 2013 981 the socket would remain live if a CTEK was connected and charging before the car was locked, on my 2016 981 it does not. Presumably if your CTEK has been connected up and charging, disconnecting only from the mains end may just possibly leave a residual circuit from the car to the CTEK which subsequently drains the battery? Dunno, but I would try disconnecting it at the car too and see if the problem persists.
 
Thank you both. Yeh I will try unplugging it from the armrest. This is what I used to do but assumed the socket would just turn off after a period of inactivity, and turn on again when I unlock the car (purely just to make the socket live so when I connect CTEK back to mains it worked).

I guess there might be a residual charge that's draining the socket. When I turned the ignition on today and got the low battery warning there was a subsequent warning 'Low battery. 12v socket off,' so think that may well be the case.

Weird there are different experiences between different cars of the same generation, Brian. Thanks for sharing
