I did confirm, it works with every Porsche on the battery registration EXCEPT the Macan. Sorry guys.

Just wondering if they've managed to include this functionality now... after 4+ yrs.

 

I might be wrong. This is a cut&paste from a thread:

"I have an update. I emailed both Autel and iCarsoft customer service. I asked about the 2019 / 2020, but assume the answers would be similar for earlier years as well.
Autel: The Autel MD808 Pro (available here for $233) does support Battery Management System, and allows you to register the new battery on a Macan. This is per Andrew Libert @ Autel
iCarsoft: The older iCarsoft Por II does not support BMS. However, the iCarSoft V2.0 (available for $146 here) does allow you to register the new battery on a Macan. This is per Barnett Davies @ iCarSoft.

So, it sounds like there are at least 2 reasonably-priced tools which allow you to reset the battery on a Macan for DIY people (like me). If anyone on this forum ever does it successfully (or tries it unsuccessfully), please add to this thread!"

Sorry bout that. Guess it does...


Well then I take back my take back. Or something like that. Bottom line, I was correct in my initial spin on this. Thanks for the update Shark!

This is so confusing....so are these two confirmed to be working for battery registration and more?

 

Also check out the OTOFIX D1 Lite, made by Autel. Scans a ton of car makes, and will do PDK calibrations, all the service resets, live data and bi-directional actuatons of individual components.

Got mine on Amazon, and couldn’t be happier with it.

Can also register a non-OEM battery?

Yes, there's a battery replacement/registration function on the OTOFIX D1 Lite.
For non OEM battery replacement, read through THIS forum thread...

 

Just replaced the battery in my 2017 S. Bought a Duracell AGM Platinum, H8, 92Ah 850 CCA on sale for $180.00.
Prior to installing the battery, I took a picture to help with the registration process.
Suprise, the battery has no serial number. None, nada nothing. I ended up fabricating a serial number from a couple of numbers below the barcode and adding characters to total 15 characters. Used the part number from the old battery and changed one number. Used a Foxwell scanner and registration was painless.

 

Looks like you got your East Penn, USA made battery at at Sam's Club.
Which Foxwell model did you use?
Now that you have registered the battery, are you able to go back and see the registered information from the car on the tool ?

 

Hello all,

I really hope this is the correct place to post this. I recently acquired a 2018 Macan S and replaced its battery. Purchased the iCarsoft POR 2.0 from Amazon and thought I was off to a great start…

My issue seems to be that when I connect the computer to my 2018, and enter then vin, it shows me my vehicle then says “car not supported” 😭

I attached to to my 2023 Macan and it runs just fine….

I just want to clear all the errors so I can drive my car properly.

Has anyone had this issue? Should I return the iCarsoft I bought for a different one?

Thanks,
-Me

 

iCarsoft products can be great or not. There is no way to find out in advance, unfortunately. Their support is both slow and awful. From what I have read, the unit you purchased should support your 2018 model. Have you updated the software on it ?

 

Hi everyone, I will be needing to replace the battery for a 2018 Mecan S soon. I'm wanting to ask what about a good stock replacement and if there is any reason to stick with a Porsche branded battery? Thanks.

 

There are only a few companies that manufacture batteries (Johnson Controls, Exide, East Penn), which are then relabeled by a huge number of companies. Any given company may even use multiple suppliers. The Porsche branded battery is made by Varta, a subsidiary of Johnson Controls. So there are no dramatic differences between brands in terms of quality, but pricing, warranties, and availability vary. Costco has a good price on Interstate batteries (recently bought one made in Germany FWIW). Walmart EverStart batteries are also popular. You need an H8 AGM and can read about registration in this thread.

 

Yes, Costco does have a great price on the Interstate battery. Thanks.

 

Can someone confirm a scanner (icarsoft, foxwell, etc) that will allow me to do battery registration on a 2020 Porsche Macan S. I scoured the icarsoft POR V3.0 website. It lists the Macan BUT says some models dont support this but doesn't say which ones? Any help would be appreciated.

 

Anyone on the scanners for non-OEM battery registration?

Does this one work?

Amazon.com: iCarsoft POR-II Porsche OBD-II Scanner Tool Multi-systems ABS SRS : Automotive

Does Launch have one that works? Thanks.

 

FYI - I've been corresponding with scanner companies to try and get a straight answer as to what scanner will allow battery registration function in my 2020 Porsche Macan S. Below is a summary of their replies. I chose the "Foxwell NT710 for Porsche" model. I have not used it yet but will report back after I install the battery.

Icarsoft said: only the POR V3.0 will work
Autel said: MaxiCOM MK808BT Pro
Foxwell said: the NT530 and NT610 will not work for battery registration, go with the NT710 single model (Porsche)

Hope this saves others from the frustrating back and forth emails with customer service reps that have no idea what they are talking about and just kept referring me to their website. Finally, I got answers from the Technical Service departments....we shall see how accurate the answers were? It shouldn't be this difficult to tell a customer what scanner does Battery Registration?

iCarsoft technical support is really bad. I have read numerous reports here that the POR V2.0 will work with updated software. The V3.0 I used worked but like many other products, will not display the installed battery info after installation. It can be inferred that a new battery is present from the other data which is availabile, like internal resistance, for example.

Also, iCarsoft make many other more costly and more capable tools. I seriously doubt that "only the POR V3.0 will work".

 

I agree. It should not be so difficult.

 

Walmart only has this battery in stock for delivery...

http://goto.walmart.com/c/404739/56...Start-Platinum-BOXED-AGM-Battery-Group-Size-H8-LN5-49-12-Volt-900-CCA/380996471

It says BOXED... will this work on 15 Macan S?
TIA

 

Yes. If you take it out of the carton / box first. This is the same battery as in the stores, but shipped in a box.

 

2020 Macan S - DIY Battery replacement and registration completed. I'm an "office worker" not a mechanic but when the local dealer quoted me $1,100 to replace the battery I decided to try it myself. Here is a quick summary.

I purchased an OEM Porsche (Varta) battery from PorsheSilverSpring (MD) for $362. Part number "000 915 105 CE". It matches same parameters as OEM battery in the vehicle 92Ah.

I hooked up my CTEK battery maintainer to the under hood front battery posts to maintain power to the car.
Followed the many youtube videos available on how to remove the battery from the boot and reinstall new battery
Then used an Autel MD808 Pro to register the battery to the vehicle. Purchased from Amazon for $259. Tool was "OK" it let me enter the battery data and register the battery and gave me a "registration successful" message but I couldn't go back and look at the battery or confirm that a registration had occurred.

Only other lesson learned which I'm sure you guys already know -- I used a standard battery tester with alligator clips to test the CCA and volts of the battery. However, I discovered you don't get accurate readings if you test the battery from the front posts as opposed to the battery terminals. The readings on the front posts were way lower than the actual readings when taken on the battery terminals. So, obviously, something is lost in the cabling.

Hope this helps others?

Congrats on saving a bunch of money !
My comments:
a) You missed the opportunity to save an additional $182.16 with Walmart's Everstart AGM H8 by reinforcing your Porsche dealer's overcharging habit. These batteries have a slightly better 95Ah rating and a 3 year warranty. Mine was made by the same company that makes Varta (Clarios) for Porsche and was Made In Germany less than a month from the date I purchased it in the Southeast USA.
b) Did you use "Supply" mode on the CTEK ? If not, NEVER use a battery maintainer to power your car during a battery change because they do not provide a consistent power supply and they could throw an error and stop completely if no battery is present. Some CTEK models have a "Supply" mode, which is what is needed. some do not. You could have had an unpleasant surprise. You can also jump to another battery during the change.
c) Be sure you plug the unused vent hole with a newly supplied plug or by removing the one from the old battery and reusing it in the unused port.

 

Mataa: thanks for intel on Ctek, I didn't know that. I also have a Stanley BC25BS, I'll have to check and see if that has a supply mode. Luckily it's operating normally so far 🤞

 

When swapping the battery would it be a bad idea to use jumper cable from another car to supply the 12v to the terminal and ground under the hood of the Macan?

 

Perfect. That's what I did.

 

You wouldn't even need to do that. You could use a small 12v lawn mower battery or a 12v gel cell battery used for electronics. That would be enough to maintain memory settings on all the various devices in the vehicle.

 

If you use a small battery, ensure that no large consumers of power are switched on.

 

I think its past time to replace the original battery on my 2015 S. I have almost 80,000km on and have had a few starts lately, where it's cranked a little slow and dash warning msg saying only rear wheel drive available. Drive for 5 mins, pull over and restart and it's gone away. Also, it's taken a couple of days for my CTEK to show fully charged. I generally drive the vehicle about 3 times a week and only ever leave the CTEK on when I'm gone for a month but I realize a 10yr old battery is overdue for replacement. I had a local guy that did all my previous oil changes etc and he had the scan tool but has now retired. Did the last oil change myself and didn't worry about the reminder but sounds like a new battery definitely needs the scan tool use or if I use the same 95Ah battery available at Costco, can I get away without registering it ?

This has been discussed in great detail. Short answer. Yes, you can replace the battery without registering in via a scan tool, BUT you risk shortening the lifespan of the replacement battery.

 

Some time ago a poster decided he would install a battery without registering it and keep us updated. If you are still on this list we would love to hear from you.

 

The potential issue with not registering the new battery is not merely a shortened life for that new battery.
It is also potential damage to the alternator & maybe other parts of the charging system.
IDK if true but, vaguely recall reading about that somewhere. Alternator working harder since it 'thinks' the new battery is old & need more charging.

I also would like to hear from some longtime MF members who tell us they changed their battery, did not register it and their battery is going strong at 7 or 8 years!

It would also be nice to hear from some people who replaced their original battery and their new battery failed in 2 years or 3 years, etc. My guess is there are not enough people on this forum who kept their Macan long enough.

The diagnostic tool to register the battery and also turn off the oil change nag screen is not that expensive and the procedure for replacing the battery and registering it is very well documented in this forum.

I recommend "Launch CRB5001" scan tool ...very easy to use & works on my MY 2016 Macan & MY 2019 911.
I had originally purchased Autel Maxi AP200, in 2021, to use with smartphone. It was very cumbersome to use & did work to register Macan battery. But years later, did NOT work for 911. When I called Autel, their customer service was very bad.
When I pointed out that when I purchased it the Amazon listing said and still says:
"Access all modules for your selected manufacturer.”
“For use with all 1996 & newer OBDII Compliant Vehicles”

For my 911 kept getting: “Service: No Sequence Available”
Autel told me will not work on cars newer than MY 2017!
I said:
"Why would you sell a tool in 2021 that would NOT work on the past 3 years of cars?"
He said Amazon is not an authorized dealer and if I would've bought it from Napa auto parts or some other authorized dealer, they would've disclosed that it wouldn't work on any car past 2017.

So Buyer beware if purchase Autel Maxi AP200. Make absolutely sure it will work on your MY car.

 

I do not agree. Here's why. The Macan's BMS tracks 23 different battery related parameters. It is designed to use this information to manage battery charging in real time.
Note the first 4 listings below. All are related to the condition and age of the battery. It seems more then a little implausible that the BMS would "willfully" ignore all of this real time data in favor of treating the new battery like an old one.

There is no data I've ever seen anywhere to support the contention that the BMS will harm a new battery and alternator if it is not registered; only supposition.

To further prove the point, hook up a voltmeter or pull up the MFD voltage display and, once the battery is fully charged, you will observe perfectly normal system voltages in the 13v range with a good battery. If the BMS were overcharging, you'd see system voltages in the 14v range or higher.

The complete list of battery data I observed from a scan tool is shown here:

• Battery aging, charge related (%)
• Battery aging, output related (%)
• SPECIFIED battery internal resistance
• Battery internal resistance normalized
• Battery charge condition
• Battery charge condition smoothened
• Extraction charge
• Open-circuit voltage
• Battery detection cancelled
• Battery voltage
• Battery current filtered
• Battery current
• Battery temperature (acid)
• Battery temperature (pole)
• Closed circuit current limit dropped below (permanent)
• Closed circuit current limit exceeded (permanent)
• Watchdog reset status
• Communication status
• Battery sensor status
• Counter voltage threshold 1
• Counter voltage threshold 2
• Counter voltage threshold 3
• Wake-up reason

 

You make a good case but, if you are correct, then registering the battery is simply a scam by Porsche & several other manufacturers, just to get more $ from customers who need the dealer to change their batteries so the dealer can register the new battery.

So, have you personally changed a Porsche battery & not registered it?
If so, how old was the old battery & how long have you had the new, unregistered battery in the car?

FWIW, My old Macan battery routinely showed system V on the MFD of mid to high 14s.
Immediately after I installed & registered the new battery, it routinely showed low 13s.

However, my new battery (Made by Clarios, the maker of the OEM Varta)was 95Ah & 900 CCA.
OEM Varta was 92 Ah, 850 A EN. (EN ≠ CCA.)

IDK what the system V on the MFD would have been had I NOT registered the new battery.

 

Though I think Porsche are not completely well-intentioned, I do not think battery registration is a scam per se. Or at least not a complete scam.

First, Porsche direct us to register new batteries. HOWEVER, nowhere have read that Porsche have warned about battery or alternator damage caused by not registering it. Turning the focus back now, where have you read that Posrche have provided this warning? Has anyone seen such a warning from Porsche ? Who has observed damage to a new battery or alternartor ? Anyone ? Without either of these, I suggest we stop making these warnings.

So, what then is the reason for the registration requirement ? From experience we know that:

a) Registration makes it easy for a tech to see when a battery was replaced, its serial number, type and rating without looking at the battery itself. (Not exactly a huge benefit to an owner.)

b) If the battery type is changed (e.g. AGM to Flooded Lead Acid), then it can be useful for the BMS to know this because ideal charging voltages for different battery types can vary and the BMS can lilkely not be able to detect the change. The same may be true when installing bigger or smaller batteries than stock as the increased or decreased response to charging may be misconstrued by the BMS to be an issue.

c) Installing a new battery and registering it will not automatically restore functions that the BMS disabled due to previous poor battery health. Of these systems, the Auto Stop-Start feature is the most commonly disabled system. I have also noted intermittent problems with the distance sensor used by cruise control and emergency collision braking. This fact is interesting. When I replaced my battery with a brand new, fully charged one, and then registered it, Auto Stop-Start still did not work. I was really concerned by this. What did happen is that the car immediately threw an error directing me to drive the car upon starting it up for the first time. After a brief drive, Auto Stop-Start began working again. And my distance sensor has never mal-functionned since the new battery either. My explanation for this is that the BMS knew something had changed because of the registration, but it did not simply take the registration information at face value. Instead, it wanted new data to base its charging regimen upon. Driving the car provided that new data. Another poster described charging the battery after registration and he did not receive the error. I think it's because the BMS was able to collect the data about the new battery's response to charging it needed, without driving.

My working theory is that the BMS constantly collects data but does not react immediately to new data. Registering the new battery wipes away the old data. This speeds up the adaptation to the new one. However, until the new battery is charged (by driving or on a charger) it does not change anything. The BMS needs new data the BMS needs to decide how to behave. In theory, you could have replaced the old battery with a defective one, so it wants to collect and analyze data with the new one before changing its behavior and before re-activating systems. Not registering the new battery simply lets the old data persist for a while until the new battery's behavior can generate new data which is then integrated into the BMS's behavior. In the meantime, nothing shocking is going on. There are no facts to suggest that the BMS will overcharge a new battery. System activation may take a little while longer because the BMS waits to collect enough data to be "convinced" that the current battery is capable of runnig those.

d) This is where Porsche is suspect. They designed this wonderful and very capable BMS system. But that same system NEVER provides a warning to the driver that the battery's health is not good or that systems are being disabled, despite it having access to the same data we collect when we use a stand-alone battery analyzer to determine battery health (internal resistance etc.). Why is that ? Why does the BMS start disabling systems while never alerting the driver to the issue causing this ? It will throw some errors but not about Auto Stop/Start and not about the battery. I am quite cynical about this. I think that Porsche thinks that if owners are alerted to a battery issue, some may try to replace the battery on their own, like I did for <$175. Porsche prefers that you take your car to the dealer and complain about the systems which have been disabled. Once there, they like that the dealer will diagnose the issue and get to offer you a $1,000 battery (with registration). Once you are already at the dealer, they are banking on you rolling over for the abuse you will get, instead of walking away, like I did many years ago.

e) If the dealer performs the work, they will charge the battery or drive the car before it is returned to you. This will restore the disabled systems. And this allows them to claim they did work to get these things going again, or to simply justify the $1,000 battery charge. For $1,000 you deserve something you can observe. A new battery, with no other change in car behavior just does not feel as good..... if a gouging can actually feel good.

 

While I do advocate registering it, common sense tells me that "Start-Stop" causes far more wear on critical components, including the battery, than failing to register it in the BMS. I disabled that "feature" immediately after obtaining our Macan.

 

I agree. However when you disable the Auto Stop/Start feature you also lose the energy efficient coast function too. This causes the engine to rev higher on deceleration when not needed. So the wear and tear gain is offset to some degree, if not completely. And gas mileage gains are also lost.

Personally, I like the coast feature on the highway and dislike the Auto Stop/start in urban settings. So I have to keep remembering to turn it on and off depending on where I am, which is a pain. That Porsche combined these 2 features together is a shame. Another example of questionable judgement on their part, or simply biasing for gas mileage for their own reasons, without considering their customers preferences.

 

The only reasons Porsche added the "Start-Stop" feature was to help meet EPA standards and to make people feel good about saving a miniscule amount of fossil fuel. The cost of a starter or a battery at Porsche prices far outweighs the cost of fuel saved.

 

For those thinking of ordering/shipping the Everstart battery from Walmart...think again. Last week Walmart shipped me a 850CCA Everstart AGM battery (made in Korea) when I had clearly ordered the 900CCA Everstart AGM battery on their website. The battery they shipped me isn't even available on their website. Talking with a Walmart representative on the phone gave me zero confidence that a second attempt would be any different, so I chose to return the battery (via FedEx ground, their cost) and drive the 1/2 hour to a local Costco and pick up the 900CCA Interstate battery there and save on their $50 shipping fee. And to go further down the rabbit hole, the Interstate battery from the Costco store has an item # that is different from the same battery listed on the Costco/Interstate site (see attached pic). I mentioned this to the Costco rep. and he said "yeah, they do that often". Tricky business this battery replacement game is.

 

Interesting. I had written long ago that these big retailers often multi-source the same product from different vendors. I had read about someone from the Phoenix area having had the same problem you did. Just last month, I purchased another Walmart Everstart H8 AGM battery from them (for a different non-automotive purpose) and received the same Clarios / German made 900CCA product I received back in 2022. So the experience you had is not universal. I am in the south-eastern US. Where are you located as this could be useful info for readers here ?

 

Picked up a 95Ah 900CCA Energizer battery from Costco, part# 2387650, to replace the 10yr old 850CCA 92Ah Varta original. Fully charged both with my Ctek on AGM mode, then hooked up a slave battery and the Ctek to the front booster terminals. Then swapped out the batteries, taking care as terminals would obviously have current. Don't have a scan tool, so didn't register but did make a note of the serial # in case of issues. Seemed to work well and have had no issues since, I guess time will tell. Btw, no need to disconnect subwoofer. Just unbolt and rotate to left side and leave it out of the way while you swap the battery.

 

Picked up a 95Ah 900CCA Energizer battery from Costco, part# 2387650, to replace the 10yr old 850CCA 92Ah Varta original. ...

FWIW, OEM Varta is NOT 850 CCA. It is 850 A EN.
EN ≠ CCA
