Agree. It is a 1 hour clock time job, max. The battery is easily accessible and removable. 30 minutes to change batteries, 10 minutes to register in PIWIS, 10 minutes to clean up and 10 minutes to drink coffee.

There are members on this site who claim to have received information from Porsche service advisors that a retrofit from LiFePO4 (expensive) battery to AGM (less expensive) battery is possible. So far no member has posted a list of parts (harness) to make this retrofit.
Anyone who is considering replacing the LiFePO4 battery should ask their service advisor for the retrofit, if it exists as some members on this site claim.

This definitively proves that the 9Y0 platform can be made to accommodate either AGM or LiFePO4 batteries.
Parts (harness, and possibly a module) and coding are required to make this happen.
It would be a big help to the community here if anyone can post:
- parts lists
- service campaigns or TSBs
- service department invoices
documenting the changeover from LiFePO4 to AGM.

'19 Cayenne with Battery Light
Our Cayenne battery light is on, took it to dealer. Dealer says battery is not responding to system queries (I am paraphrasing) and the battery needs to be replaced. Presented with a $3000 estimate (I think $2600 for parts) and perhaps a six week wait or more, I am in a bit of shock. The battery seems to be working okay, no fluctuations or anything, but every time we start we get a loud warning chime. Does it make sense that it needs to be replaced? Is getting a third party battery an option to consider? Should I start trickle charging it? (I don't think there is any evidence that it is not charging). Any thoughts appreciated.
Rob.

This is a common defect, there is a thread or two on this site. It's unfortunate in Porsche's choice of a lighter and much more expensive LiFePO4 battery compared to a traditional, heavier and far less expensive AGM battery.

This whole battery issue is frustrating. You cannot expect customers to be ok with a 3k-4k battery replacement bill. My quote was over 4k, but I dug my heels in and got the dealer to replace at no charge. You will need a specific charger for this battery as well. My standard chargers didn’t recognize the battery. I would press your dealer again

Is the LiFeP04 battery covered by the OEM warranty?

Yes, but they have many caveats to wiggle out of coverage.
This Warranty Does Not Cover:
Batteries damaged from storage, lack of normal vehicle use, or nonPorsche approved electrical or accessory installation.
So what is normal vehicle use? Well, they explain it in gory detail. Good luck complying with it . . .
Your Responsibility for Normal Vehicle Use
Porsche Guidelines specify reasonable mileage to be at least 15 miles / 24 kilometers per day or 6,000 miles / 9,600 kilometers per rolling 12 months.
— If you drive less than the above-mentioned limits, or in the event of prolonged storage, contact your local authorized Porsche dealer for instructions.
(Note: A battery maintainer is available at your local authorized Porsche dealer. It must be used to maintain your vehicle’s battery state of charge if your vehicle will not be used for several days.)
Bottom line: Contact your dealer, tell them you drive less than Porsche’s guidelines, and let them sell you an overpriced, Porsche-branded CTEK battery charger, and document it. THEN, you should be covered.
When the $2,000 battery craps out, show them the documentation and tell them you had the battery maintainer connected any day you drove only 14 miles, rather than the magic 15. 😎
