Battery Replacement and Maintenence
My 2.5 year old battery that I got free from Costo to replace my Optima that I got free from Costo to replace the Optima that I bought from Costo died. They no longer handle the series 48 batteries that fit Porsches.
Geeze, I wonder why? Anyway they cheerfully refunded my purchase price of $85 cash. I looked around town and ended up buying a 75 month 3 year free replacement for $77.
While I was under the hood, I was amazed at how clean everything was. I picked a small leaf or two out from near the drain area and wiped a bit of dust off stuff. It still looks like a new car under there, not bad for a '99!

Yes, just bought my 4th battery using the same money that I bought my fisrt one with. Car just turned 60k about a month ago. My free time for pleasure drives is split between a few motorcycles, a Jeep and the Porsche. It's not practical for me to use as a DD.

It is only 18 AH (a normal battery is 70 or 80 AH).
997.611.020.00 Battery (lightweight) -- US MSRP $2373.76 (no typo that is the price). How many would you like?

I just put in an interstae H-7. As noted here by other posters, it is a perfect factory replacement fit, just drop it in and bolt it down with the factory base clamp. Interstate's website recommends an MT-41 but the MT-41 is physically smaller and requires a spacer to make fit.
My car had the MT-41 in it, and would crank slow when the engine was warmed up. The H-7 spins fast and works much better.

Just adding my data point. I just replaced my battery now. Autozone specs out a Duralast H8-DLG. When I brought my original battery to Autozone, the Duralast H8-DLG was a bit longer than the OEM battery for my 2004 C4S. Luckily, I asked the salesperson to check with me what alternatives they had. We put my battery next to some other ones and found an EXACT size match. Here are the specs below. It cost me $145 with the $12 core charge ($157 without).
Duralast
Part Number: 94R-DLG
Weight: 47.4 lbs
Warranty: 8 YR
Application: Automobile
Cold Cranking Amps (CCA): 730
Core Charge Applicable: Yes
DIN Designation: H7
EN Designation: 77L4
Height (In): 7.5
Height (mm): 190
Length (In): 12.4375
Length (mm): 315
Width (In): 6.9375
Width (mm): 175
Weight (Lbs): 48.5
Post Location: Top Post
Reserve Capacity (Min): 140
Right Or Left Hand Positive: Right
Voltage: 12
It's a bit pricey but still better than the $250-$300 or whatever Porsche is charging nowadays for a battery that probably doesn't have the same cold cranking amps.

Are you sure the length is 12.43 inches on your battery that seems too long to me??
