Battery Registration - Rennlist - Porsche Discussion Forums

Macan - Battery Registration - Given the interest in this, I thought rather than bury it in my lengthy battery disaster, I would do a separate thread and should the Mods deem it worthy turn it into a sticky. The question posed is how to code a non Varta (in this case an Interstate brand) battery...

rennlist.com

My Original battery is still good but My plan is when I need a replacement to buy:
Bosch Premium Battery

$164.99 (after their online promo coupon) {This inf. is from several months ago so YMMV}

Interstate Batteries | MTX-49/H8

I have the Bosch battery in my old Jaguar. Which is infrequently driven & it has held up well + it has 92 Ah... exactly the sane as my Macan OEM Varta. I will just want to "inform" the Macan computer that there is a new battery with same Ah as OEM & I will need to trick it with a fake serial #.

From photos of these batteries, I have determined that either the Bosch or the Interstate will be able to be installed with the correct +/- orientation in the Macan battery compartment. (I do think the front label will have to be hidden/backwards on one of them)
I plan to buy the Autel MD808 Pro tool to register the new battery. Some people are going to NOT register it & take their chances.
Siberian detailed exact procedure/instructions WITH photos ~ 4-13-2020... or perhaps b4 then & that date was just replying to a question I had asked him.

I C/P pix & instructions for my own use. (But from this thread)

Replacing & Registering the Battery

Hopefully I will not need to do this for 3-4 years but I’m curious. Manual p. 314 says only have done by Porsche dealer & you cannot tell what type of (aftermarket) battery will replace the genuine Porsche battery by the markings on the battery. WTF?! I like Interstate brand. Often better...

www.macanforum.com

Read some b4 & some after.

I think you basically make up a serial # with 15 digits, you can use a 14 digit # with an added space.


Good luck.

Thanks, that is what I thought. None of the 670+ posts documents the successful installation and registration of an aftermarket battery.

Alessia3 replaced his/her battery with an aftermarket Varta, and successfully registered the new battery using an Autel MD808. See posts 440 and 445.

Petervv did the same with an Autocraft battery purchased at Advance Auto. See post 558.

Thank you, I was wrong. the posts that you referenced are very helpful and they answer the question regarding registering an aftermarket battery.

 

[Digby]

I am going to order an Autel MD808 Pro. Has the price gone up significantly? The least expensive one on Amazon is $247, and the least expensive I can find is it JB Tools for $229.

According to CamelCamelCamel, about a year ago this was selling on Amazon for $177.

I am happy to report that I was able to register an interstate H8 battery I bought at Costco for ($177 in California) using the Autel MD808 Pro. The interstate battery has a serial number that is only 12 digits so I added three spaces at the end to make it 15 digits. I reused the part number (7P0915105C) from the Varta original battery from my 2015 Macan. Again, I added one extra space at the end to make it 11 characters long. To my surprise, none of the memory info was lost (basically the driver seat setting and FM radio presets). Thanks everyone for the helpful posts and suggestions.

That is great to hear. Thank you for posting!

So how do you think your installation got past the memory settings aspects while you did the swap?

I bought mine on Amazon for under $200. I was not in a hurry and kept monitoring the price. One day it just went down to $177 and I bought it.

Arnie, thank you. Was that on Amazon roughly a year ago?

Has anyone gone to an independent garage for battery replacement and what was the cost?

One of the indys I use told me to expect about $450 including an Interstate battery and labor.

So say $180 for the battery leaves $270 for labor ( and I bet they tack on a disposal fee to that, sales tax for those in States where they do that...) you're looking at over $500. I do one battery change (let alone anything else I do on 4 different cars - Audi, VDub and Macan) and my Launch has just about paid for itself. And I don't restrict myself to one make of vehicles.

For some of us health and age is an issue. Prior to my heart issues there was very little that I could not do on any of the vehicles that I have owned through the years. Sadly, that is no longer the case. I was forced to change the battery in my Aston Martin about a year ago (I believe the same size and make as the Porsche) and had to hire someone just to lift out the darn thing. For me an honest independent makes sense.

Of course, I'm 70 so left my teens a while back. But definitely understand, apologies.

Honestly, I am not sure. I did not have a battery maintainer hooked up and so I was prepared to lose all the settings although all I had was the driver seat memory and FM presets. It would be 5 mins of extra work so did not think it was a big deal.

Yes

My 2016 Macan S needs a new battery.
I contacted a local dealership and the parts rep told me that the dealership will install the OEM battery or an Interstate battery equivalent. The prices: OEM = $534, Interstate = $305. In either case, they would charge one hour labor = $170. He said they have Porsche's permission to sell the Interstate batteries, and they mostly sell the Interstate batteries.

I've talked to two independent shops. They both quoted me $289 for the Interstate battery and $50 labor.

Based on your help and the above, I plan to have one of the independent shops make the install for me.

Cheers!

Interesting that the Parts department was quoting the labor charges. At least you are not getting the absurd price quotes that some others here have.

 

[SomeBeach]

The Parts guy said he understood there was a one hour labor charge. The service dept told me their labor charge was $170 per hour. So I guess the labor charge was a combo of the parts and service depts.
Cheers!
