Is it worth the extra $60-75 for Bosch S6-95R vs. a NAPA BAT 9895R battery?

Same rating (AGM, 950CCA & 105AH). The only difference I can see it the Bosh has a 4-year warranty vs. the NAPA 3-year.

I have a AUTEL MaxiAP which I should be able to use to register the new battery, correct?

There are only a handful of battery makers (Bosch is not one of them) and hundreds of battery brands. Ask NAPA who makes their batteries. Be aware that some may be made by one company while others, by other companies. This is sometimes true even within the same product description and retailer if they are large enough. Also, look at the country of manufacture for another hint. My Walmart Everstart AGM - Made in Germany battery looks identical to the Porsche OEM battery right down to the mold marks in the plastic housing.

 

call me old fashion but I purchased the Porsche OEM battery from dealer for $350 and put it in myself and registered it with an Autel MD808 Pro. Car is still under warranty and I didn't want any excuses if I have to take it in for warranty work.

It will be difficult to register it without Porsche battery because you need to enter the number from the battery and it doesn't seem to recognize other format numbers.

As has been written here multiple times..... it is easy to register ANY battery. Simply use the correct number of characters for the part number and serial number fields. Make up your own numbers or letters. It does not matter.

 

I'm sure that works too but how much are you really saving? Why fudge it. I'm sure all three batteries mention work fine. Good luck whichever you decide to go with.

 

A few hundred posts ago, I stated that I replaced my battery with the 92ah from NAPA which, at the time, was manufactured by East Penn/DEKA. The case was identical to the original that I removed. After "registering" it to the vehicle, it works as intended. Obviously, the battery speaks German. 😊

 

I just did an Interstate search on Costco. The H9(95R) AGM is $270 in-store. That will do it. Not worth $140 for an extra year of warranty on the Bosch.

 

Costco warranty seems to be prorated now. Napa is 3 years. Interstate is 3 years.

Walmart Everstart seems to be 4 years.
The EverStart battery four year Free Replacement period begins the day of the purchase and expires four years from the date of purchase.
EverStart Platinum AGM Automotive Battery, Group Size H8 / LN5 / 49 12 Volt, 900 CCA
$179

Has anyone found the Varta at VW or Audi for cheaper than getting it from Porsche?

 

The Varta brand battery for Macan, as are many other different brands' batteries (e.g. Interstate and Wal-Mart Everstart AGM in certain regions of the country etc. etc. etc.), is made by Clarios one of the few large worldwide makers. That's why the many mold marks on my German made Wal-Mart Everstart AGM were identical to the ones on my OEM Varta / Porsche battery.

 

That Everstart battery is a winner.
It replaced my OEM battery in my 2020 Macan Turbo perfectly (4.5 years old) and has operated perfectly, without a hitch. I registered it as a 95AH battery with a scan tool and never looked back. Just be sure to check the date code before Walmart purchase and try to get the newest one on the shelf.

 

I just saw this post. Which scan tool did you use to register the battery in your 2020 Macan Turbo?

 

PIWIS data is from a few days ago. Battery tester is from today.

This is the original battery from 2020.

I also was able to code out the
Recuperation setting.

 

@Sajan , I must have missed this discussion on coding out “recuperation setting” What is the benefit of this?
thx

 

Hi. this is where I saw it:

https://www.macanforum.com/posts/2798477/

 

It’s really interesting, but we do not have recuperative or regenerative braking in Macan, ICE models anyway.
We have “coast” mode …….but this is not the same.

I still really like the idea of 14.4 being applied in comfort mode. I do see this fall to 13.8 after some drive time. As discussed Sports and Sports plus see 14.4 in the MFD.

 

Found some more info.

From the 2015 Macan SIT.

ChatGPT summary:

• Recuperation Function (All Macan Models):
  • Converts kinetic energy into electrical energy during deceleration (e.g., braking).
  • Energy is stored in a high-performance starter battery.
  • Generator voltage is actively managed to optimize charging and reduce engine load during acceleration.
  • Stored energy powers electrical systems during acceleration, allowing full engine power.
• Generator and Voltage Regulation:
  • 3 kW generator (220 A, 12–16 V) supplies vehicle electrical/electronic systems.
  • Voltage regulated by a LIN-controlled voltage regulator, managed by the gateway control unit.
• Energy Management:
  • Battery sensor data sent via LIN to the gateway control unit.
  • Gateway uses intelligent algorithms to calculate energy needs.
  • Generator adjusts output based on gateway's request.
• Additional Controls:
  • Braking and load response info comes from the DME control unit.
  • In stop & go traffic, the gateway can request higher engine speed to boost generator output at idle.

 

 

Either way, I am also going to try this. If comfort mode remains looked at 14.4, this might be a good thing. Right now after some short period of time, in comfort mode mfd switches from 14.4 to 13.8.
Sport and Sports plus always locked at 14.4.

 

I wouldn't put much value in the google AI result.

Refer to the page I posted from the 2015 Macan SIT.
Page 220.

"All Macan models feature the recuperation function."

 

agreed, and thanks for posting that.

 

This appears to be the Battery topic with the most recent posts so I will try asking here.
My 2020 Macan S has ~45,000 miles and went in-service in November 2019. There has never been a battery problem or related trouble code. I am only replacing the original VARTA 7P0915105C AGM 92AH battery because it is 5.5 years old and we are leaving on a 3000+ mile trip next week. The new battery is a Costco/Interstate H9 (95R) AGM, 100AH. I used my 12V test bench power supply to keep the vehicle live while I changed the battery. Everything works fine, no loss of settings or new trouble codes.

The problem, like so many other members have reported, is registration. I had an Autel Maxi200AP but found it would not work on 2020+ so after much research I ordered a Foxwell NT510 Elite from Amazon (returnable). Pelican Parts recommends it on their website and the Foxwell website says "Battery Change" is supported in "Special Functions."
The NT510 does not work! When I connect, go to Special Functions>Battery, is reads "Connecting with vehicle" for a few seconds then returns "Not support this function" I did the built-in update via wifi and still acts the same.

I spent a good part of my working career as an electrical/electronics technician so I like many here am very doubtful the battery registration really does anything to the charging algorithm. I could get into a long discussion on how "smart" battery charging works, but as many others have said there are far wider variables the charging system needs to compensate for than a small 9% change in the battery capacity and any aging. If it can learn to compensate for the effects of aging, it can unlearn that compensation. Based on current vs. voltage vs. time, the charging program should easily relearn and self adjust for any small change in capacity.

All of that said, I would like to register the new battery if possible. I sent Foxwell a support request and will see what comes back.

Bottom line, is anyone here able to confirm the NT510 Elite or another cost effective scantool will successfully register a new battery with different specifications in a 2020 Macan S? Most of the battery registration success stories I have read are about pre-2020 models which I understand have a different gateway.

Only Porsche knows what they are doing with the battery coding info. All I know is the info is there for the BMS and DME to use. I don't see why Porsche would out of their way to design all this if it didn't use that info for something.
But is your car going to explode if you don't program it? probably not.
will it affect the longevity of your battery or your charging system? maybe.

I know the iCarsoft 2.0 can do the coding. I've done it on my 991 before with it.

here's some of that age related info..

 

I had the same problem with NT510 and had a hard time finding a manufacturer who could confirm it would do the battery registration on my 2020 Macan S. Finally, after a lot of back and forth I did it successfully with an "Autel MD808 Pro" It still wasn't exactly to my liking. It allowed me to enter all the parameters, register the battery and it said registration successful.

 

Not sure? This is picture of my Porsche OEM Battery that registered successfully with that tool. Maybe try these numbers and see if it works. I'm pretty sure you need to use one of those numbers on the QR code sticker.

I believe you are mistaken. You need not enter any particular set of numbers / letters for the serial number and part number fields. You DO need the correct number of characters (11 and 15 respectively) to get the registration to work. Spaces are counted as a character.

My best guess is that given the extra work needed to uncover the battery, Porsche thought it would be nice for a tech to read off the info in the event of a warranty claim, right from the PIWIS tool. There is NO WAY the BMS need to use anything other than the battery type and capacity to make it work optimally. And registration serves to delete the old battery health info from the unit so that BMS can start to work optimally from the get go. However, even without this, it would still learn that there is a new behavior from the battery and adjust accordingly. The only thing that would not be ideal is to not register a different battery technology because different battery types need different charging voltages for optimum performance. Keeping the same type (e.g. AGM) would not cause any issue of that kind.

Exactly what I was thinking when I posted yesterday. The AH of a battery changes with age and cycles (decreases) and the BMS has to adjust. I believe the BMS will learn the new battery as long as it is the same type. Providing a reset and the new AH just speeds up the process.
The only thing that could be a problem is if the BMS can only learn for the AH going down and not back up. I doubt this is the case because a battery’s AH can improve with cycles after a long rest or low temperature spell and the BMS should be able to handle that.

 

Thanks so much for the info. Oddly my VARTA OEM has a 10 digit PN. I was using the wrong number for the code. I see the one between the ** is 15 digits.
I will try again with 11 and 15 using the Interstate numbers plus Os.

You're welcome.

 

Looking for some troubleshooting assistance. Last week I replaced the battery on my 2020 S with an Interstate 95R/H9 (Canadian Car, came with 105AH Varta). Following the replacement the PCM screen is black and will not power up. Fuse to PCM looks to be fine. I am getting PCM communication fault codes with my Autel scan tool. I had a small 2 amp Noco tender hooked to the battery terminal posts under the hood during the battery replacement. Any ideas on what the issue could be or what went wrong during replacement.

 

I can not speak to the specific fault causing your issue, however, the car needs power provided during a battery swap. This power must be a steady source of voltage from a POWER SUPPLY. A tender is NOT a power supply. A tender analyzes the voltage from a battery and uses that info to deliver the correct voltage and amperage based on its charging / maintenance algorithm. e.g. My CTEK tender will throw an error and stop working if not connected to a battery. Also, a 2A POWER SUPPLY is likely too small to be adequate. My 7A CTEK has a power supply mode and that will work as long as major power draws are turned off. Not all chargers / maintainers have a power supply mode. Old fashioned chargers are power supplies.

 

what mataa said....your 2 amp Noco did not supply continuous power to your vehicle. For that you need dedicated charger with a continuous feed power supply. Unfortunately, I cannot help you with the blank screen. I have not experienced that before. I know this seems minor but might be worth trying. Search on the forum how to do a PCM reboot, I think it's hold down the Volume button for 20 seconds. Maybe somehow with the power interruption the screen got turned off and you just have to turn it back on again? Good luck.
