Replacement Battery Information
I posted this on the 997 forum but I believe the 996 takes the same battery.
Battery Replacement - Public Service Announcement
--------------------------------------------------------------------------------
I've seen a number of threads concerning battery replacement and the confusion regarding which Interstate battery to use.
Well, my 5 year old Moll Porsche OEM battery finally refused to hold a charge last week. As a result I searched and researched for the proper Interstate (my chosen manufacturer) battery. I saw a lot of confusing threads regarding MTP-91, MTP-93, MTP-H7, MTP-H8, etc.
I decided after talking to my local Interstate retailer, Interstate Factory Rep and checking the physical and electrical characteristics to go w/ the Interstate MTP-H7. It's sized perfectly (fits the OEM footprint) and it's CCA is better than my Porsche OEM battery.
It has a 24 month (no cost) replacement and after that an 85 month pro-rated warranty. I didn't compare the weights to the Moll battery but my 'grunt' scale (lifting it out) suggested the Moll was heavier.
Product ID: MTP-H7(Automotive Truck)
Short Description: Interstate - 85 Months
Cold Cranking Amps: 640
Voltage: 12
Termination: A
Pro-rata Warranty: 85
Weight: 46.3
Width: 6.89
Length: 12.4
Height: 7.48
I paid close to $190 but I've been told it can be bought for less.
This is simply public service announcement. I have no interest in Interstate and the accuracy of the specifications are not guaranteed.
I'm just all charged up (pun intended) that I was able to find an 'exact' replacement in size w/ better performance & warranty.

Maybe true.
However, I wanted an Interstate battery. When your car is sitting dead in the garage and jump starting is becoming a nasty habit looking around for the least expensive battery wasn't an option.

Here's the problem. The Interstate battery and the Costco batteries are both made by Johnson Controls. Perhaps the Interstate is built to a better spec, I don't know, but $190 is more than three times what the Costco one costs. My Costco battery has worked fine for more than two years.

There are really only 3 high volume battery manufacturers out there :
Delphi, Exide, and Johnson Controls Industries.
Each makes batteries sold under several different brand names. Delphi makes ACDelco and some EverStart (Wal-Mart) models. Exide makes Champion, Exide, Napa, and some EverStart batteries. Johnson Controls makes Diehard (Sears), Duralast (AutoZone), Interstate, Kirkland (Costco), Motorcraft (Ford), and some EverStarts.
$190 is absolutely ridiculous. I guess we can consider that a stimulus payment to somebody.
An Optima red top (Optima is also made by Johnson Controls) for my Mazdaspeed6 was only a $139.

I didn't think my Interstate battery info sharing thread would bring out so many replies. Good to see that the the art of interactive communications is not lost on this forum.

Not to derail the OP too much, but for those who might consider the Optima, it takes drilling 2 holes to mount it. Not hard. And I would not recommend spending extra money on a "custom" mount.
