What I did to get around that was to take off the battery tray, put a stainless steel bolt with a star washer through the bottom of the hole so the bolt/star washer was upside down, and then re-installed the battery tray.

I replaced the Porsche battery with a Tire Store version - works fine and had a 5 year warranty!

I have always used Costco batteries in all my Porsches.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Nees to replace my 2001 Carrera 911 battery. Does it need to be a dealer purchased battery? They want $350.00 to replace the battery. Wonder why so expensive. Anything special about the Porsche battery I should know??
Any specially recommended battery??
The question is why would you even consider buying a battery at the dealer
Just pick one up like previous poster said and install it yourself, Interstate, DieHard, etc... will all work and it is maybe 10 - 15 mins max to install. very easy.
Why so expensive? Because Porsche.
It's the same as any part you'll find on a VW or Audi, but it's for a Porsche so it's 3x as much.
Porsche exhaust? Two mufflers with 8" of pipe coming off off the outlets? $1500.
Dual 2.5" turbo-back exhaust with 3" downpipes for an Audi S4? $550.
New front axle for an Audi S4? $110.
New front axle for my C4S with identical CV joints and axle shafts that are half the diameter? $500.
Friends don't let friends buy Interstate batteries. 'Cus they suck. Really bad. Something like this is far more appropriate ...

Autozone is great, they've been buying me new miata ignition cables for years! I think they gave up on selling Interstate though and switched to Duralast? Still, I'd rather spend twice the $ and get twice the battery and half the hassle. It's just to much of a pain in the butt when they fail.
Any aftermarket battery with the right size and terminal configuration will work fine. I replaced the Porsche battery with a Tire Store version - works fine and had a 5 year warranty! Way less money.
Go with a Autozone, SAMS, DiHard, Interstate, etc...go with whatever you want just dont overpay. Purchase the correct model for your car and make sure it has a vent for the vent tube.
The Duralast I bought has a pretty tiny vent hole (94R-DLG). The tube fits in but I had to really force it in. I assume this is normal. The old battery had an oval shaped vent tube on the back that had an adapter to fit.
What the heck is with the battery posts? This is the third, no fourth one this week (today)!
Winter kill batteries? I guess the cars get used less?
Huh?
I stand squarely in the middle of the fence on this one. Interstate, about $125 out the door, installed AT the dealership, BY my dealership, recommended BY my dealership. I didn't even have to recode my radio when they were done. They took care of the discard (a 7 year old Interstate), and washed and vacuumed my car before handing me the keys, an hour after I arrived.
As always, not all Porsche dealerships are created equal. Your experience may vary.
Got mine at autozone for about $110. It's exactly like the one that came out of it except it doesn't have Porsche printed on top of it.
It starts the car and everything. Just like the Porsche battery.

When researching batteries, I discovered that every battery brand in the world is made in one of 3 factories... so just look for the best price and longest warranty that you can find. Do not buy based on advertising because it is all just hype.
Installed the Group 49 battery (Sears Diehard Advanced Gold AGM battery, 850 CCA)... it takes up the entire tray and the retainer attaches to the last hole (the one without the threaded pre-attached nut).
What I did to get around that was to take off the battery tray, put a stainless steel bolt with a star washer through the bottom of the hole so the bolt/star washer was upside down, and then re-installed the battery tray. I bought the locknut, washer and bolt at Home Depot
Next, I put in the battery and battery retainer and fastened it down with a stainless steel nut with a nylon insert (or lock nut).
The battery tray allows for a open ended wrench to be slid under to hold the bolt while you ratchet down the nut. You will have to remove the black panel that is next to the battery on the passenger side of the car (very simple, just one torx screw) to get your hand in there with the open ended wrench.
Perfect fit, and a 1-2-3 solution for the bolt hole! Total install time = 4 minutes
I was quoted $395 by my Porsche dealer today for a battery and 1/2 hour of service to install.
Found a direct replacement for my 2001 911 Carrera at Pep Boys for $129 installed. It is a Bosche and has a 3 year replacement warranty and a 96 month prorated warranty. It was a Group 91 size.
Pretty much any group 48/49 (euro H6) battery will work, but I HIGHLY recommend going with an AGM battery. I've just seen to many Interstate and Duralast batteries die early to ever trust these brands again.
I've had the big Bosch from Pep Boys in mine for about 5 years now. Flawless. I give a rats *** about the extra weight there. I want the car to start effortlessly every time I need it. It's sat for weeks, and never an issue. I've had many Duralast batteries over the years, and I agree, they Dontalast. They are just cheaper.
most batteries are all made by the same factory. i had a walmart one. was the cheapest.
make sure you connect the vent tube. you don't want a battery to explode. also wear eye protection and long sleeve in a cool, ventilated area when working on batteries
Mine died this week, after not starting the car for 3.5wks. Is it normal? it was on a battery tender up until then.
Will check out Kirkland brand from Costco, good price and good reviews.
Are there ways to get around this?
Are certain online vendors cheaper to deal with?
Can you get the OE branded part for cheaper, instead of buying Porsche branded parts?
(Like Sachs struts instead of "BMW" struts)
