I was told by a Field Tech Red if the lighter works with the key removed, should be good to go!

Well I have the 6 from the kit, bought a 10 for $13 and if it's to big when I finally get my car, I'll breakdown and buy an 8...lol

Well, thanks for being the guinea pig for us. Let us know how it works out.

This question came up before. All of the outlets work for a period of time (I think it's about 15 minutes) after a door is opened even with the key out of the ignition. However, they then shut off again. The last time the subject came up I tested this by plugging a 12V phone charger with a light on it that I could see from outside the car into each of the receptacles. After a while each receptacle shut off.

The thing is, this apparently doesn't matter if you're feeding a charge back through the 12V cig lighter to the battery. My understanding is that the circuit doesn't have to be active (IOW providing power) for the charger to work.

Yesterday I installed my CTEK quick connect eyelets to the battery. The stock M6 fit. The M8 and M10 are too big. Interestingly the neg side (terminal bolt) when facing the windshield on my car was cross threaded. It was a real bitch to undo the bolt all the way so I could slip the eyelet on. Turns out I was unable to re-tighten the terminal bolt so it's off to the hardware store to get a similar stainless bolt and nut. I am using the battery clips in the mean time.

I seem to recall that bolt being problematic. I think it's designed to be retained on the terminal clamp. I clipped the end of my eyelet so it would slide under the retaining nut, rather than over the bolt.

I did the same!! Clip the eyelet, then the nut stays on the post, retighten, all good.

I should have done that. I was in a panic...sweat beading off my fore head and the disbelief I could be having so much trouble with a stupid battery terminal bolt. I have done much more technical and complicated wrenching on these cars before and couldn't believe the trouble I was having for a seemingly simple task
I was swearing at Porsche AG.

Been there......

So I replaced the bolt....M6 shaft threads and M10 outer bolt end and nut in stainless steel. Worked like a charm. Only needed a wrench on the inner bolt as the outer one locked on the lead terminal block. Phew ! No sweat on the brow either....lol

Glad you got it resolved!

Mike, not sure I understand your comment about the plug outlets staying "open for charging".
I tried Porsche charger-with the red pilot light which is on when the charger is actually "trickling charge" in all three outlets and the light turns off after about 15 minutes of charging and no car activity. I know the light indicates charging state as I use it on my 997 and it will trickle with light on for a number of hours and then go off if the battery had been off charger for a few days.
So are we really sure you can charge through the lighter outlets? I know battery must be down as car has not ben started for 2 weeks. Do we have any reference on this reverse charge being possible even when outlets are not be provided with 12 volts?

I don't know of any reason that the 12V socket circuitry would be different on a GT3 from a Carrera, but I have used the Porsche battery maintainer on 3 previous 997's and my current 991 GTS plugged into either the cigarette lighter socket, or the one in the passenger footwell, and never had a problem. The light on my charger never goes out. It alternates as it should from the orange light to the green light indicating full charge, but never turns off. Are you sure you have the adapter plug firmly inserted into the 12V socket?

Suncoast's website says the following about the Porsche battery maintainer and the Macan. Obviously, the GT3 is not a Macan, but maybe the 12V sockets are the same:

Note for Macan "**" Macan models can't be charged at the 12 volt plugs inside the car. To bypass this, visit your local Porsche dealer and they can code your Macan to accept a battery maintainer. Or purchase the additional battery clamps and charge the battery directly.

^^The Porsche charger works fine in the passenger side outlet. Light stay on. Been hooked up for over a month. I do not have the "smoker's package" so do not know about that outlet

Hold it.... Wait a minute.... If you use the pigtails to go directly to the battery you will destroy the battery monitor which operates from the neg terminal. You instead need to use the grounding post. Connect the red lead to the pos side of the battery and the blk neg lead to the grounding post NOT the neg terminal of the battery....
