Rear wheel steering is not the only way to get lithium battery. Porsche also makes it standard in many countries, particularly ones that have areas of cold weather. It is standard in Canada , I guess it is not in the US. I live in Vancouver, pretty mild climate compared to a lot of the USA… we don’t get too many days below freezing.
Porsche does say the car needs to be on a battery tender or driven. Follow the instructions. In this situation, I find it’s always better to be be polite with the dealership and not demanding. The dealership is your advocate in convincing Porsche to cover it.
Thanks for the detail, honestly not sure I see the true benefit and even with 2X the life a regular batter still had more value based on the cost. It was an option on my Speedster which has RWS …..sounds like a Porsche money grab.
I just called my friend in Jacksonville, Fla. and read him all the feedback here! There is only one Porsche dealer in Jacksonville. He is going to call his sales person and let them know about the feed back about this on Rennlist. Stay tuned!
Brumos was an excellent dealer when I lived in Jacksonville…not sure how they are now that they changed hands.

RE: “Porsche does say the car needs to be on a battery tender or driven.”
I think that applies for all batteries if not used with any regularity…and especially as the battery gets older and loses capacity.
Yes, I agree with you that the dealership should be your advocate. But I question whether the supposed warranty restriction, initially mentioned by the OP, is actually a Porsche requirement (ie, have to have driven at least 6K miles before the warranty kicks in), or whether it’s the dealership playing mind games? If the latter, then clearly, that dealership is not your advocate.
My experience over the years - not all dealerships are morally or ethically honorable.

Porsche is very clear that the car needs to driven 9600kms per rolling 12 months OR be put on a battery tender to keep the battery healthy. They specifically state warranty for battery is void if this is not followed.

Really? I must have missed that? What I remember was that Porsche “recommends” that you do that. I read NOTHING that mentioned the battery is voided if you don’t. Furthermore, and speaking as an engineer, I would love to know how they would determine if you had not put on a battery tender during that period? How would they distinguish between the battery being drained/depleted by something in the car (ie light left on), and you ignoring their “recommendation”?
Please link to where it says that? Thx

Also, if you are wondering how the dealer knows if the battery wasn’t maintained. They have a series of tests they can perform , and they can download all the information necessary from the cars computer. A 2020 with 5k miles was definitely driven below warranty guidelines and needed to be on a battery tender.
be nice to the dealer, do not threaten them in this scenario , because it definitely appears to be user error
Umm, the only part that talks about voiding the warranty has to do with the use of non-certified Porsche parts. Which I understand.
Again, I read nothing that specifically states your battery warranty will be voided if you forget to put it on a trickle charger, or can’t drive it 6K miles per year. That would be insane.
Nevertheless, and even if true, how they could prove that your battery drained because you didn’t leave it on a trickle charger?

This kinda makes sense as I read it, but I would argue Porsche should do a better job with advising customers. It’s our job to read, but Mclaren provides the charger with the car and they give you clear instructions when parked in your garage 100% plug it up. My car is 2016 and 97% battery life. Sucks all around, but plug them guys regardless how much you drive.
While draining your battery is a hassle for the owner, it’s just good sound practice to either drive the car or put it on a tender (which is why Porsche recommends you do so). But the facts are, as I understand it, if the LiPO4 battery is working correctly, as designed, once the level of charge is down to 10%, the battery’s protective circuitry is suppose to disconnect itself from the car’s systems, thus preventing further depletion, and possible irreparable damage. At that point, it is basically an open circuit, like batteries sitting on the shelf…so if further depletion were to occur, it most likely would be due to an internal short in the battery itself. Ergo, a defective battery that Porsche would have to cover, under it’s warranty.
Recommendations and guidelines are just that…common sense advise/suggestions. It would be totally unreasonable (and IMO, legally unenforceable) for Porsche to require that you dive your car X amount, or otherwise keep you car on a tender…lest you void your warranty. There are a million & one reasons why someone might have difficulty complying, eg, parent critically ill and you need to care for them for an extended period of time, you are having major surgery, you live in a high rise condo that has no provisions for re-charging your car, etc…

Link that says Porsche can tell if put on a trickle charger?
Before i bought my 992S, I was looking for a used 911. I can’t begin to tell you how many 2-3 year old used Porsche’s I looked at with only around 5K miles on them. Low mileage Porsche’s are quite common.
All the facts are not known, so you have no idea who’s at fault…and neither do I.
