I checked the serial number of your battery, and I am pretty sure that it is a lead acid battery.
You will find a picture of the LFP battery in this thread (I found it after asking here):

I have a brand new CTEK LITHIUM US Charger/Maintainer for sale, never out of the box. Bought this before my 992 C2S arrived expecting the car to have a Lithium battery, alas it had an AGM battery in it so I am selling this one.
$80.00 plus shipping (Cost me $110.00)

Doesn't this charger with the lithium mode, also have a "normal" mode for AGM and traditional batteries? It's not exclusively a lithium charger, is it?

Brings up another question - if you do have a lithium battery in the car, do you need a special jump starter device for it? Most of the jumper starter devices I see (NOCO, etc) seem to indicate they only work on lead/acid batteries.
Frankly, given all these twists and turns, cost for replacement, etc - I think I would prefer a car that came with a traditional lead-acid/AGM battery.

WE make a Harness Kit for our XP-10 Jump Starter 9 which also works on some other brands, but not NOCO) that you can connect to you battery so that you can jump start, or in the case you over-discharge the Lithium Battery, or Lead/Acid Battery in your car you can still get into the frunk by energizing the battery Terminals where you connect this Harness too. So you don't need to get into the Fuse Box and mess around with trying to connect a Jump Box in that area. So it much simpler but also allows you to Jump Start the Car also.
This Harness allows you to Plug in our Mini Jump Starter and not need to access the Cars Battery itself since the Harness is routed out to the edge of the Windshield. You simply plug this harness into the Mini Jump Starter and your car will be Energized which then allows you to open the frunk or jump start the Car. There are a few options of this Harness that fit some other brands of the Mini Jump Starters, but with a Modern Porsche like the 992s you want about 16,000 millamp Jump Starters or more, that is why we suggest they XP-10.

To answer your question in some circumstance they dont want you to hook up a jump starter directly to the terminals of a Lithium Battery because there is a Circuit Board called a BMS Battery Management system inside the Lithium Battery itself, but additionally there is an IBS Intelligent Battery Sensor attached to the Lead/Acid Batteries Terminals. So you would want to make sure you connect to the Postive and then the Grounding post rather than the Negative Terminal of the Lithium or Lead Batteries themselves just to keep from somehow damaging and sensitive components inside the IBS or BMS...

The posts on the LiOn car battery are further apart from each other than the AGM battery?

The battery dimensions and posts should be similar, but the manual recommends attaching the jumper clamps to the Positive battery post (which is on the passenger side of the battery) and the negative clamp to the chassis ground post which is near the driver's side suspension point (not the battery negative post).

Costco had a two-pack of Duracell branded 4A automatic maintainers. I think it was $80 for two. They have a lithium-ion setting (might be auto-sensing).
I've been using them on my wife's car and a motorcycle for a year with no issues. They come with both clamps and pigtail harness with fuses.
