Default 12V battery low, please connect to charging equipment

I've got this message from my brand new 4S. What could be the problem and where could it be charged?
Thank you

A number of threads have been started on the topic of trickle charging your 992. If you search on Rennlist, or even YouTube, I’m sure you will find.



But in short, you can trickle charge (make sure you have the right one - ie, if you have the Li battery, you need a trickle charger suitable for re-charging Li batteries)…from two locations…the 12v socket in the front passenger well and if you open up the protective cover found in the frunk, you will be able to directly connect to the battery.

The source of the low battery could be varied, but in most cases, it’s not serious and once you re-charge and use your car with some regularity you shouldn’t have a problem. If the prob persists, you could have a defective battery, or an internal drain on the battery that should be identified by your service dept.

Thank you so much for the answer.
I already read those threads on how to charge the battery before I create a new thread but I thought those threads are irrelevant to my case because I picked up my new 992 4S yesterday. Therefore the battery should not run out.
But I think I didn't count the days the vehicle stayed a week at the PPF shop before I pick.
Thank you.

A rough rule of thumb I’ve seen on here is - If the car is inactive for a few weeks or longer (eg, say away on a trip or vacation), put it on a trickle charger to avoid coming home to a dead battery.

Since your car is new, no doubt it sat idle at the port, on the ship, at the PPF installer, dealership, etc for a long time…and even when driven, it was only for very short distances/periods of time. Today’s Porsche’s have electronic systems that run in the background, even when the car is closed and locked. That slowly drains the battery. I suspect if one were to disconnect the battery, so there was no electrical drain, the battery would not deplete for a long period of time.

One reason why most on here subscribe to the philosophy that letting a car sit for long period of time, is not good for the car (unless you take the necessary “storage” steps).

Stupid question...is there any rhyme or reason as to whether or not a car gets a Lithium Ion battery versus conventional batter?

Rear axle steer vs. non-steering; Lithium vs. conventional.

Thanks! I have a leftover trickle charger (conventional) from our C7 Corvette and was hoping the P-Car when it arrives would have a conventional battery (cause I'm cheap).

No RWS for us here, so it looks like cheapness wins.

I have RAS, so I have the Li Battery. Supposedly, Porsche replaced the conventional battery, which is about ~40 lbs heavier, with the Li battery. A weight saving trade off to off-set the additional weight from the RAS mechanism.

Also, the Li battery has (about twice) the lifetime of the standard Porsche battery….but, when you do need to replace in 8-10 years, it’s 2-3X more expensive.

By then prices will have come down to AGM levels and you'll have bought the next generation leaving this worry to...another or set a reminder in your iCal

Detail guys often leave doors open when working on the car. I had a E63S getting detail work done and it kept sending a email about the battery. Probably just need to drive it to get it charged back up.

With the battery weight savings, the RAS option actually nets out to less weight. Of course the non-rear axle steering folks can always add the lighter battery at their choosing

Porsche included a Charge-o-mat Pro and adapter with my C2S (lithium battery) delivery, not exactly a ringing endorsement of the battery system on this car.

You may be looking at a gift horse in the mouth. Any (modern, electronics laden) car that may not be driven regularly needs a trickle charger. I think you dealership recognizes that can often be the case with a 911 and gave you a charger as part of their SWAG - it did not come from Porsche. My dealership also gives you a car cover as part of their SWAG; is that some expression of concern about the quality of the 911's paint? I also get a couple of hats, but, in fairness, that could definitely be an expression of concern of the attractiveness of my head.

Bumping this thread because I experienced something almost identical but ran into a twist. I have a new 2024 GTS with RAS. As a result, I surmised I have a Lithium battery based on comments on RL, so I purchased a CTEK lithium charger. I went to connect it this evening after taking delivery today, but my battery is an AGM battery, so now I need to figure out a new charging solution. Any idea why I don’t have a lithium battery like others here?
