[GH85Carrera]

Phew, another "fun" chore done. The battery in the Macan is changed out and it is the exact same battery as my 911.

It is pretty straightforward getting the old one out, and loaded in the back of the El Camino. Tied down to keep it sliding around and drive the 5 miles to the Interstate battery center. I loaded it onto the tailgate, and slid it forward to the tied down. Some kid in his 20s just hoisted it out and put it in the dead pile. The old gray that loaded it was happy to use the tailgate, and slide it forward method.

Got the new one in, and hooked up, and turned on my Autel OBD2 reader and it had told me the old battery was at 57% and 11.4 volts. The new one is 12.1 volts, and all happy. The hardest part is typing in the 15 digit serial number, and it HAS to use capitol letters, and numbers. So constant back and forth between the digits, and then letters, and hit the upper case arrow then the letter, and back and forth.

The part number from the old battery part number was too short so I added a 1 and it was happy. Mrs. Carrera is happy as everything works as before, the windows know the spots, her key put her in position 1. The trunk lid opened and closed as it should. It even remember the time.

I had to change one digit on the old serial number and that made it happy.

The Porsche dealership wanted $750 for the battery, and I know they would have charged 200 bucks or more to plug in the computer and reset everything. The Interstate batter is 95 Amp hours and the old one was only 92. Both are AGM batteries.
