Time for new 12V battery?

[Ciprianbadic]

Hello there! Long time no post but truly enjoying my Taycan as much as 111.000 km in less than 4 years.
I noticed that my voltage is staying at 14.2V consistently for the past few days, whereas typically is 13.5V.

Is that a sign of a used 12V battery? Is the alternator is having a though time charging it?.. it’s not normal. Please let me know if someone noticed it before.

P.S 111.000 km with original 12V battery. Thank you and hope you enjoy yours as much as I do!

I am looking forward to hearing from others on this as well. My thoughts are exactly the same as yours because my 911 also shows 14.3V while my TT shows 13.4V. However, even after sitting the garage for 2-3 weeks I can start the 911 right up, and I can hear the starter spinning quickly so no sign of a weak battery. Currently, I have a '25 Macan EV with 2800 miles and it too shows 14.4V. I have it for a month now, and we've put over 2k miles on it and it still hasn't dropped. So, that helps put me at ease about my 911.
