Interstate Battery Replacement - Public Service Announcement

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

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.

In the spirit of sharing...I had a Les Schwab XTreme Power Battery installed yesterday in my 06 997c2 - it was recommended by a Porsche Service Manager. It cost $99 plus $10 install.

Have never heard of Les Schwab Tire Centers. Are they local to you ? They don't make their own batteries so could be the model you bought was made by Interstate for them and explains the similarity of the two.

I'll reach out and provide any relevant updates.

I believe they are NW only.

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.

Did you find a local Interstate dealer and rep via an internet search? My battery has never really been anything beyond merely adequate. And if I accidentally kill the motor shortly after a start, it's difficult to get it to crank sufficiently for a restart (not to mention the embarrassment of having the guy in the Bimmer chortling behind me!)

Just replaced the Moll OEM battery in my 2006 911 C2S. Local dealer (Carlson Porsche) uses and recommends MTP-91. So, just got MTP-91 and it fit perfectly and the car started . We'll see how it does long term.

(Local dealers -unnamed to protect the guilty- wanted $350 for battery and install!! )

Also, dealer explained that car would need to be reset after battery change. If that wasn't done, would get warning lights including air bag warning light that could come on at ~100miles after battery change.

We used a battery power adapter plugged into the cigarette lighter on the center console. Seems this didn't work to keep power to the car. (Lost interior lights when we pulled the battery.) After installing new battery, first two starts of the car got warning (PASM or TPMS wasn't paying attention). Third start didn't get warning lights.

I chose the slightly larger MTP-93. It fits perfectly using the farthest mounting hole. I simply inverted the mounting bolt to secure the new battery. Now up to 830 CCA.

Just replaced the battery in my '06 997S Cab with the Interstate MTP-H7 you guys mentioned.... exact fit and couldn't be happier.

Thanks to you all !
