Quick question for the people here. Does it matter which thread I connect the positive pigtail to? I've seen pictures on the forum of people connecting to option 1 as well as option 2 in the image below. Option 2 was easier for me since there was already a nut there that I can use to secure the cable. Wanted to confirm if this approach will lead to issues down the road?
Thanks!

Do you plug it in with the car on as noted in one of the posts above or not necessary?
I had no issues for 2 months of plug in use through the socket. I would toggle just the carl electronics car on/off , while the charger was (Noco Genius 5) plugged in.
It's tricky the way the the car adapter port works. I actually sent a PCNA message to make that an option in the PCM. There are so many other useless things in there, but we can't configure the outlet to be always on after turning off the car.

Either Option will work. My recommendation is Option #1 in your picture. Just buy a Stainless Steel Nut at your local Hardware Store that fits the threaded stud. It will be a Metric Size, like a M10, etc.
The Nut on Option 2 in your picture may not come all the way off by design, yet you will need to try it. Here is a picture of my 991.2, using the threaded stud similar to what you call Option 1.
Batter Tender Cable Connections Direct to Battery.

So, basically, plug in charger, turn on dash, turn off dash, let it charge?

Yes, I think that was it. Having the charger plugged into the wall outlet and the key power outlet and charging, then I would just toggle the electronics/ignition on/off.
I would let PCM boot up.
I think that was the procedure. I should've written it down.
I should add. You check about 30 minutes later and see the charger is has gone off.

Missing one important step-lock car. If you don't, the charger will go off in 30 minutes-that is what happened when I did not lock the car as the last step. Don't just turn ignition on and off must wait at least 1 minute.
Plug into footwell
turn on ignition and wait 1 minute or so then
plug charger into wall socket and make sure green lite in on
turn off accessories
Lock the car!!!!
This is what I do for my CTEK charger.

Good suggestion. This is exactly what I did. So simple. Works perfect. Took ten minutes, if that. My CTEK eyelets were already the correct size.
Is there any risk in keeping a battery tender connected virtually anytime the car is going to be sitting for more than three days? In other words, is there an overcharge or related risk?

That was only an issue with old trickle chargers. Modern intelligent battery maintainers like CTEK, NOCO, and Porsche rebranded CTEK units got into float mode so there is no such thing as overcharging.
I had no problems with my CTEK 7002 charger until this morning. My set up is in my December 2023 post in this thread. I waxed the Porsche today and when I reconnected the tender I noticed it was clicking; never heart that before. I checked my connections to the battery and everything looks good. The cable that connects to the battery has a light flashing green the way it is suppose to.
I tried another of my tenders and get the same clicking. The tender goes through the different lights on the tender but so far has not gotten all the way to the final light where it is suppose to turn green. That usually takes at least an hour.
My only guess is there is something wrong with the Porsche battery. Even though I only have 4000 miles on the car, it is a 2020 and I live in Arizona where batteries do not last as long as other parts of the US.
I do not have a voltage meter to check the battery; I guess I can go buy one this afternoon.

Any other ideas?
Thanks.
My 7002 does the clicking as well. It’s always periodically done it. I assume it does it when it’s in float mode. Had it on 24/7 for months on my air cooled cars during the summer. Used that 7002 for 6+ years. My lithium-ion CTek is quiet as a mouse.
You can always turn the ignition on without starting the engine and read your voltage display on the dash. But a voltage meter is always good to have.
