>> The Porsche battery seems to be problematic and very expensive.
There are many pieces involved in this system - I don't think anyone has 'proven' the Li battery is the actual issue itself (though that's certainly possible). Problems have also been reported with the 'smart' battery management system, ConBox parasitic drain, software, among others. It's simplistic to say 'Li bad, AGM good', though clearly something is wrong..
You are absolutely correct that there are many pieces to this....Porsche's system software did create high parasitic drains/loads that caused the batteries to drain below a certain threashold, and then caused a permanant lock out protection of the Porsche Lithium battery. The Porsche Lihtium Battery was completely at fault for going into a permanant lockout when simply getting a bit over-discharged, and then not being able to wake itself up to be able to function or be recharged again. So on that specific piece of the problem they didn't build a good Lithium Battery, so you can point at the battery for that specifically. But Porsche over complicated that battery to a high degree in efforts to make a "Proprietary Battery" so the regular user could not use any other battery but THEIR Porsche battery. This is a normal ploy by many larger corporations, but pretty ridiculous being that a battery is a component that must be redily available always.
Anyway as a little marketing chime, our Antigravity Battery can't and has never had that issue of not being able to wake up, so it isn't the chemisty of the battery that will cause the problem neccesarily, but rather the engineering or in their case over-engineering of a product.

Interesting - sure more will post MY24 examples soon. Without getting into the complexities of the lithium battery, somewhat disappointed from a weight standpoint. In isolation won’t make a difference, but overall with other options it all adds up.
I wonder if there will be a retrofit to the AGM battery, if the lithium fails under warranty?
that would be a lot cheaper for porsche plus less of a pain in the *** if you have a problem.!
hopefully a retrofit to the AGM will be possible if you have a problem with the lithium after the warranty is up and you don’t wanna pop three grand for a new one
My '23 T, non RAS car has the lithium battery installed as standard equipment. I haven't had any issues since my delivery in late June. However, with the reported battery problems and until there is a cost effective solution, I would highly recommend the use of a battery maintainer, especially if the vehicle isn't being driven on a regular basis.
I'm personally using a Noco Genius5 maintainer, it has a force mode feature that will allow charging if the battery goes below 1V.
