Dude, Please dont do this YOUR SA is a dick
Dude, Please don't do this YOUR SA is a dick (ie. not a good guy) and if you do this we all get to pay the Porsche tax situations like this enable. There is a video how to on replacing a battery on here and anyone with a borderline IQ could perform this task. Any battery will work I recommend the AGM Bosch from pepboys asit comes with a 5 year warranty but make sure you check the manufacture date (you want it within 4 months of today) . Your battery requires no programming (per another thread on RL). I have a 2012. and the original battery is perfect. Don't replace parts for the sake of replacing parts or because your stealership SA needs a new tommy chu chu for his 8 year old.
Dude..
My car is in the shop for some warranty work (new pistons for rear deck lid, window drop fix, and a newly found transmission leak (only needs a new transmission pan!)) and my SA, who seems to be a good guy, mentioned that my battery is starting to go. He offered to replace it for a whopping $796. The battery itself is $406 and the "programming" is $390 (including battery test, charging test, and replacement labor).
I've done a little research on this, but I thought I'd give some more info about what my SA is saying about the "programming." "The new Porsche battery comes with a code that gets programed to a few computers to allow full communicate in the vehicle . You will find that something will not work or will stop working if an aftermarket battery is put in and the programming is not done."
Does this make any sense? What could possibly stop working if the battery is not programmed? I've asked my SA, but have so far gotten no reply.
I figure I could get a better battery than the Porsche OEM one for about $200 and install it myself in about 30 minutes, according to threads on this board.
What am I missing here?

Dude.
I bought a Duracell battery last night from Batteries+ for about $200 and will replace the current battery on my own when I get the car back tomorrow or Thursday.
Video certainly makes it look easy. Hopefully there won't be any snags.

I do believe the car has to be reprogrammed when you replace the battery. I think it regulates alternator output and charging based on the condition of the battery. I know we had to do this on our Z4 after I replaced the battery, but the indy didn't charge us anything when they were doing another service on it.

Can you use one of those "pocket" battery jumpers on the interior in the fuse box instead of the Porsche battery tender?

Has anyone replaced a 991 battery without "programming" it and had any weirdness?
If it only reduces the battery life, I could buy 4 aftermarket batteries for the cost of a single dealer-installed battery. So even if the life is reduced to 2 years, I'd still get 8 years from $800 rather than the 5 I'd get from a dealer-installed battery...

ironically I believe my original porsche battery was needlessly replaced by me (it was almost 5y old so no harm done). I since bought a really good tester and it tested fine for its age, once out of the car. What tricked me is that the 991 draws a crap ton of current when you open the door or hood to even check the voltage... it always reads low initially when checking that way because it's sucking electrons and the alternator is not yet running... I've since added pigtails for the ctek that exit by the base of windshield - I recommend you do that when changing battery, perfect timing - and am able to a) recharge it without opening the car at all and b) check voltage w/o waking up the car, it's fine at 12.6 instad of the 12.2 I might see when using the dash display... Still overall I'd recommend plugging that car to a Ctek anytime it's not gonna be used for a week, it draws juice...

My car died in my garage so I called AAA. Tech had no idea that the engine was in the rear but was enthusiastic and I felt we could do the replacement together. He put a power source through the OBD to prevent loss of settings. We removed all the parts necessary to remove the battery which was simple and the only quirk we came across was that the new battery was much larger than the old one. We figured out that there are multiple holes for the bracket that hold the battery in place so the size of the new battery was not a problem. We got it all back together and the new battery has a really good warranty. Cost was $145 which is really good
