Question…I thought that an earlier post stated that with PDCC the battery would be located in the compartment in this Pic. I have PDCC but an open spot.

Yes, that was post #113 from this thread. Here’s that diagram you were thinking of:
Your picture shows just part of the battery cover aft of the actual battery. The battery is located forward of the storage compartment, which is normally larger when no PDCC 48V battery is installed. Check out these pictures:
Here’s an overview of the cargo compartment. I removed the spare tire for clarity. Note the yellow outline of the 48V PDCC battery underneath the cover.
Side view of the battery cover with outline of battery location. Note the top of the battery case is visible through a cutout in the cover.
I received a "Battery low. Service necessary" warning with yellow battery icon on dash in my 2019 Cayenne S with 35k miles. Dealer first quoted me $3128.71 for a replacement Lithium battery. When I asked if this was covered by warranty, they researched and told me there is actually a recall for the battery sensor and it will take an hour for them to address. Going in next week... I guess it is expected for dealer service dept to try for the battery replacement route before checking for recalls, but hopeful that solves the problem. I would have to shop around a lot before I would spend $3100 plus labor for a damned battery at the dealer.
anyone else have a battery sensor recall done?

WMJ9 – Re-Programming Gateway Control Unit (Battery Sensor) (Workshop Campaign)
Concerns: Gateway control unit (battery sensor)
Information: Due to a software error in the battery sensor, there is a possibility that the ageing status of the 12-volt on-board electrical system battery on the affected vehicles may be calculated incorrectly. As a result, the 12-volt on-board electrical system battery may be replaced prematurely.
Action required: Re-program the battery sensor using the latest PIWIS Tester software version.
2. There is another recent TSB just released November 3rd. (See attached PDF) Your dealer may not be aware of this, so be sure to bring it to their attention. It concerns the module called the ConBox. It is also called the Vehicle Tracking Module or the SOS Module. It communicates the vehicle’s position in case of theft or accident.
The problem is caused by the ConBox drawing excessive current while the vehicle is parked. Defective ConBoxes draw 400 milliamperes while normal total draw should be 30 - 70 mA.
There is a new software fix for vehicles produced before June 2021. They utilized a version called ConBox Low. Vehicles produced after that date had a different version, called ConBox High, and there is currently no fix available for vehicles equipped with ConBox High.

Shnave,
THANK YOU so much for the timely and very informative reply to my Low Battery error! I will definitely let the dealer know about the ConBox energy draw recall and have them address that. My factory warranty expires in February, so I definitely want the dealer to do everything possible to get stuff done while covered!

I live in an apartment block and my cayenne is parked in a public car park with no mains. Are there any portable trickle chargers that don't need mains?

Is your parking spot outside or inside? If outside, you might consider a solar powered trickle charger. Battery Tender has a selection here: https://www.batterytender.com/solar-panels
I see you live in a cloudy / rainy location. If the solar charger doesn’t work, consider the next-best option — a battery booster. I used to rely on the generosity of strangers to stop and let me connect my booster cables. No more! Now I carry a booster and jump myself when needed.
Here’s what I use. It sat in my car 4 months before I used it to jump my daughter’s dead battery. It performed flawlessly. She got one for Christmas and was thrilled. https://antigravitybatteries.com/pro...-starts/xp-10/

Thanks Schnave (long time fan of your contributions.. am giggling like a starstruck teenager).
I did read you used the xp10 and bought one on your suggestion! It worked a treat thank you. Alas, it's keeping the battery topped up that's still the issue.
Unfortunately, the car is in an underground car park so solar is not an option (and would only be for a couple of hours a year given the weather in any case ).
Just to clarify, as I have read the forum and maybe I missed something, but you can replace a lithium battery with an AGM battery and it's okay? Sounds as though newer Cayennes are shipping with AGM batteries anyway?
I currently have a 9Y0 915 105 K battery and seems like the Bosch may be an okay replacement or have I completely missed the mark? Current battery I have

There is no record of a successful AGM retrofit to an existing factory equipped LFP battery.
From the Porsche TSB, attached: ”If a standard AGM battery is installed in the vehicle, a warning message will be displayed because there is no LIN communication. The power supply network switches to emergency operation.”
The OEM Lithium battery is specially manufactured with an internal battery sensor with an integrated LIN connector. Other replacement battery companies don’t have internal battery sensors.
The factory equipped AGM batteries have a completely different battery harness that includes an external battery sensor and LIN bus connection. You would likely have to retrofit the battery harness and code the new battery type with a PIWIS.

Understood, I called the guys at Antigravity Batteries just now and they were super helpful. So is a Porsche dealer the only place to get these batteries then? Any third-party website or supplier you can get them from?

Certain large parts sites advertise them for about $1,800.
Surprisingly, I did find a source on Ali Express for $892. Shipping is expensive, $252, since it is shipped from China. Total cost $1,144 and over 100 batteries in stock, ready to ship. https://www.aliexpress.us/item/32568...andl_shipto=US
It looks like the real deal; with a LIN connector and LG Chem manufacturer sticker. Confusing description says “Test is normal.” Does that mean they are remanufactured?

So who wants to be the first Guinea Pig?
Ooo... I am tempted but waiting a month is a bit long, my battery is gone. This one is a 9YO 915 105 L vs what mine says is a 9YO 915 105 K. Anyone know the difference between the K and L?

I studied several battery labels and believe I found a correlation. The suffix letter denotes the year of manufacture, with a switchover sometime in June or July. Therefore, an L battery is newer than a K battery.
