Thanks for posting; the Walmarts around me are sort of out of the way, so i was looking at either Autozone or Sears. Got my AGM 94R battery yesterday - car cranked great after the swap. Stupid thing was that the Sears computer spec'd a group 49 (which is bigger).
While it still fit in the tray, the hole in the tray that the clamp would have to be screwed into didn't have any threads. So I had to take the 49 back and tell them to give me the 94R. 189.99.
Oh, and I had my battery out of the car for 10 hours - didn't have any issues with losing presets or time or anything like that after dropping in the replacment. PSM failure cleared in less than a minute of driving, as expected.

1) I used the battery tender hooked up to my leads when I removed the old battery and had no issues w/codes, etc.; and
2) The Interstate that I replaced was purchased and installed in September, 2013. I'm really surprised that it died so fast........
Anyone else have a quick demise Interstate story to tell?

Yes, and I forgot to mention that:

Hi guys, What vent tube do you use? My car had the Interstate MTP-91 when I got it and I just purchased the Autozone Duralast Gold battery but am finding I only have a battery vent tube with no adapter to fit the hole in the Duralast battery.
Where do you get the adapter from? Autozone says they don't have it!
UPDATE: Nevermind, I found a suitable adapter at Autozone after heading to the store myself.

Hello, I'd like to change my battery in my 09 997.2. Im not comfortable doing it myself, and not very close to a Wal-Mart. Is there another chain(costco/sts etc) I should seek out before sucking it up and using the dealer? thanks

Where are you located - maybe a forum member could help install - not difficult at all.

The closest Walmart to me is claiming the correct replacement is the H6. should I insist on the H7?

I stupidly didn't take my battery to Sears, they told me it was XYZ model, and I took it home and... it was too big. So I brought it back and told them that the info I had initially (which I got off of this forum) was correct and they needed to give me what I had initially asked for.
Good luck. It's really an easy replace and install. If you know how to loosen a bolt and then tighten it, you can do it.
