Just bought an (don't flame me!) InterState as well. Went with the MTP-91. A little smaller and 9 lbs lighter...

I was really set to get a P-car replacement to keep the original look. But **** poor parts service at one dealer and $180.00 tab, and a quote of $225.00 for the battery, plus - get this - $20.00 for THE ACID at another dealer made the choice easy.

Confident this will solve my issues (and leave $100.00 in my wallet for ). Thx R-listers..

Mitch,

Now you are working for Interstate I see. Good to have you on board.

Life is good here at Interstate, but not sure I've found the vent on the battery...

There is a small flat tube on top pointing toward the back. The tube won't fit this - is that it?

You should have received a kit with the battery that allows you to connect the vent tube... go back and get it (included with the cost of the battery).

I will most likely be getting a battery from the dealer. Around $180 with PCA discount. More money than I'd like to spend, but with car for sale soon, want to keep it as original looking as possible. Besides, the factory battery lasted over six years in a car that wasn't driven much - would another battery do significantly better...?
Your are very welcome Mitch,
I don't always buy Interstate, but they do have good service. The last one I had I bought new for my 964C2 and had for less than the warranty period. I was past the free replacement period but only had to pay a few months pro-rated value. I think the death of this battery was due to my not driving the car enough and not using a battery tender. I still don't drive the replacement vehicle (996tt), but it is for sure on a tender.

I never let anyone test my batteries in the car. I don't even let the low level mechanics, like the one you see at Sears or Pep Boys work on my stuff. I remove the components (battery, brake disks) and let them perform what I can inspect afterwards. I have a great fear of these "Technicians" ya-right, doing harm to my vehicle. I once had a car that had a defective "Die-Hard" battery and the tech (read hack) placed both cables on the new battery and then whicle tightening the positive clamp, arc'ed the chassis. I reached over and removed the ground cable and let him continue. He then ask if I wanted him to test the charging system. I don't think he was thinking that he did damage and wanted to make sure everything, he was trying to drum up work. Well if you can't keep from arcing the chassis while installing the battery, no, you are not going to diagnose or touch the vehicle anymore...

So how are things now with the new battery?

I only drove my 2004 tt every two weeks or so during the winter. Alas - it did in my battery - turned the key two days ago - windows went down - idiot lights on - no cranking. Took a charge and died again in 24 hours. Replaced w interstate 91 - fit perfect in the third hole. One other thing - the 91 has to be 10 lbs lighter than the OEM - Good Lord that thing was heavy! Car fired up faster than I can ever remember. Learned my lesson and will charge once a month now during those winter months.....
