My last two cars were some sort of plug in. I don't want to plug in another car lol

 

Might void the warranty, and all sorts of things electronics related.

 

They can't actually void the warranty... that is a dealer talking boloney. You can look at the Magnnson-Moss Act to verify this. You can put aftermarket parts in your car, and they can't void the warranty. Unless you don't put in a similar product or it illegal or something odd.

-According to the Magnuson-Moss Warranty Act: a vehicle manufacturer cannot void the warranty of your vehicle due to an aftermarket part unless they can prove that the aftermarket part was the cause of or contributed to the failure of the vehicle (15 U.S.C. 2302 (C)).-

But FYI, the battery does not mess with electronics in a car, it is basically a vessel that stores energy to be drawn on when needed, and supports the system during higher loads. The Cars system reads the voltages at the batteries and then makes decisions on if the battery is in a good state of charge or not and if too low throws flags, but the battery cannot hurt the electronics or force energy into electronics at all when you use a 12v/13v battery in a 12/13v system. Only if you used like an 18 or 24v battery in your system would it hurt it....and no one is going to do that.

The only reason Porsche, and the Owners of these Cars is tied to this battery is they put the IBS Intelligent Battery sensor INSIDE their Lithium Battery so you have to plug your connector into the port on Porsches Lithium Battery , whereas normally on an AGM equipped Porsche the IBS is attached to the Negative Terminal Clamp. So they did this to make it so you could not use another lithium battery except Porches. But there is a work around... it just changing the ground strap. We are looking for people to test this with. Because if you simply change to a AGM ground strap you plug the IBS plug into the Negative Clamp and don't have to use the Porsche Lithium Battery port.

 

Not sure if this was a joke based on the "6K miles per year" BS / caveat that Porsche tried to pull, but I don't believe this would be a valid basis for denials. It's a "dumb" (i.e. passive) battery, without internal logic to cause harm to the car.

@Antigravity Does the car also need to be correctly coded for an AGM battery? I know PIWIS has a setting for Li / AGM under the car configuration menu...

 

Has this problem with the batteries been resolved for MY2024 cars? Specifically for 2024 Carrera T with RAS?

 

Well the Lithium equipped cars will have coding for a Lithium Battery, but in PIWIS if you go with an AGM Battery as the replacement you can have it coded to the AGM setting in PIWIS. Our battery can work with the AGM setting or Lithium Setting.

 

I’ve read hundreds of posts about lithium battery issues, and I must admit that I don’t understand what the hell it’s all about.

My previous 911 Cabrio C4S had RAS and a lithium battery. Never had a problem with it but it was my daily driver, so it didn’t sit unattended for very long. My current 911, a Targa 4 GTS with RAS and a lithium battery will be idle in my garage for 12 days.

I’ve installed a CTEK charger with all the appropriate wires and attached a pic of the battery label about the battery.

Question is… If I leave it in charging mode, will I have problems in 12 days. Or should I not attach the charger and go to Italy thinking about Ducat's and pasta and not the battery?

Yes, I know this is basic but the horror stories on this list concern me.

Thanks.

 

Focus on the Duke's and the fettuccini. Forget about the battery.

 

Looks to me like you are thoughtfully well prepared. Keep it plugged in while you are gone. Very rich people with multi-car collections leave their cars connected to maintainers for months at a time. Maintainers like CTEKs know to go into float mode followed by pulse mode to keep the battery charged without overcharging so just leave it plugged in when you are going to be away for over a week.

 

Circling back on this thread. Given more of us who just receive their 2024 models, can you confirm with the RAS option, what type of battery do you get? My car’s now sitting at Benecia and pending for delivery. It has RAS and I will report back once i get it, cheers!

 

Mine got AGM with RAS. 9/23 build.

 

Configurator no longer shows Li battery with RAS.

 

My September 24 build 992T without RAS has the Li-Ion battery fitted.

 

@lizhibupt My car is being collected tomorrow and I have seen it already and ,most definitively has a Lithium Battery as per the pics above posted by @Yojeffo
Hope that helps your car will have the same I am sure. Best Devon Racer.
