Can anyone help advise me? When I connect trickle charger to the 12v socket, it charges up fine for about 15-20mins then system disconnects the 12v socket, charging of course stops, then charger shuts off. No such problem when connecting direct to battery terminals. Charger is fine. Using porsche recommended charger. Manual for car suggests this should work.

Denis,

I think this has been noted on the forums for some time for the 9x1 series cars. Doesn't the 991 have two power sockets? In which case, does the same thing occur with both sockets?

If you've not tried it, connect and power-up the conditioner before you lock the car.

If all else fails you can always fall back to the direct battery connection you're using currently. Nothing wrong with that ... and is the method I've been using successfully for nearly 10-years!

Jeff,

Isn't there some advice (right or wrong?) that you should leave ignition on, then connect charger to power socket, switch off ignition and then the socket stays live beyond switch off time. Who knows? I just use the live battery post and an earthing point.

Ralph,

Yes, that may be what I was trying to recall - and would make some sense, connecting the charger while the electrical system is live. Bit of a faff though, and much simpler to connect up using your method.

Thanks for your replies. It worked by connecting up with the key in and electrics live. Removed the key, locked the car and its trickling away nicely.

Like many I mostly keep my car off the road over the winter, but I do take it out occasionally. I will find using the 12V socket (under glove compartment) much more convenient. Using the battery terminals is messy as it requires the cover to be removed and the bonnet up. The terminals are not the easiest to clip too either and care is needed if putting the cover back over the terminals.

With the 12V socket it's a simple plug and play/remove. Nice for a quick get away when I will occasionally take it out !

Thanks so much for the quick replies.

Sounds like a result Denis.

By the way, your Porsche conditioner is just a rebranded CTEK device. They make an extension lead which can be connected to the battery positive terminal and the earthing post and fed out past the battery cover https://www.ctek.com/products/vehicle/connect-eyelet-m10 . This flying lead can then be attached to the CTEK lead passed through the gap between the windscreen and bonnet, so there's no need to leave the bonnet up. You may find this useful if in the unlikely event you experience further difficulties using the power socket.

I use the 12V socket in the passenger foot-well and this works fine with my CTEK MXS 5.0 trickle charger (991.2). The clearance between the passenger door and the sill is wide enough for the cable (2 wire) to fit through.

 
I just plug my ctek into the socket in the centre armrest then bring it out above the drivers door

the gap by the wing mirror is wide enough not to crush the cable

it’s been working fine for years
