Just got the comfort connect setup on my Carrera T (AGM) battery. I used the negative ground point that @Diablo Dude shows. Everything appears to be working OK but I didn’t change any nuts as some folks are saying they did (I just reused the factory ones and tightened down) - I wouldn’t say I’m very mechanically inclined but should I have changed one of the nuts I removed to hook up the comfort connect? (Either the positive nut on the battery or the nut I removed to do the negative ground?) And if so, can someone explain why we should do that? Thanks!

You used the ground on the firewall, the 13mm nut? That's fine so long as you loosened the factory one so you could place your charger cable lug below it. The issue with that connection point is that you can't spin a second nut on top of the factory one there, the ground on top is unreliable. On the battery posts, you can top up with a thin M6 nut to hold the charger eyelet.

So far plugging into the footwell 12V receptacle has worked fine for me. No need to run any plug or attach to a nut underneath the panels so all good w/ the the CTEK MXS-5.0 w/12v adapter on a AGM battery. Can’t speak for those who have LI batteries.

No I used a ground adjacent to the passenger side strut tower - pretty much exactly how it was shown in post 12 of this thread. I was able to just remove the factory nut (for the positive connection on the battery) and factory bolt (for the negative ground) and then put the CTEK comfort connect loops (?) on before retightening the respective nut / bolt to make sure everything is secure. It seems to be OK that’s why I’m confused as to various people talking about using an aftermarket nut somewhere. I just wanted to make sure I didn’t do anything that could damage the battery or vehicle at any point.

how have you gone getting the charger cable out the door. When I run it out under the door it gets clamped very tight by the door seal etc and I am concerned it would lead to damage to the cable or door seal over time.

I've always just plugged into the socket, without locking car, turning on PCM. Never had it stop charging, unless the plug-in order is wrong. That seems to be the only criteria. Which end you plug in first. I've never understood why people say it stops. I've done this on 6 different 911's with about 3-4 different tenders. Maybe the 992 is different but I'm going to attempt the plug first.

And the cable doesn't seem to take damage running under the closed door.

So I dropped an m6 nut trying to adjust the comfort connect. It's somewhere under my battery. Should I care that much? Couldn't get it out with a flexible magnet. What am I risking leaving it there?

Sorry I missed your question but I just crack my window open and run the cable out.

It rattling around, that's about it.

This may make me sound stupid. But here you go. Had my 911 for a little over 3 weeks and gave it it's first wash this weekend. Anyway, popped the frunk to dry it off, and there was a Porsche branded charger and connecting loops in it. I had already purchased CTEK charger and loops. So for those of you taking delivery of your 911, may want to check the frunk for a charger. Maybe this is standard...just caught me by surprise.

C21ban

Must have been a gift from your dealer as it’s not standard, at least from US dealers.

Well if thats the case then shout out to Porsche of Austin for the trickle charger. They also sent me a box of gourmet foods. Obviously a small drop in the bucket for the cost of the car, but nice and unexpected. Got to work for those reviews and repeat business.

I drove it today and didn't notice anything. Guess I'll just leave it. Don't want to be removing the battery just for that.

If the magnetic pickup can't find it, you could try a high powered shop vac narrow nozzle - dig it around in the gap and see if you can vacuum it out.
