Any updates on how that went? It is now feb 28,2022 and my new icarsoft POR v2.o would NOT register my new battery, even with the old varta bem code I got errors try again when I sent data. Sending it back tomorrow. My new battery has been in for a few days working fine unregistered.My new one was the same...95AH replacing 92AH. close nough.AGM batteries also do not like being overcharged and it will shorten their life.
For what it's worth I did the swap a few weeks ago and did not register a new battery. I doubt in my case the battery will be overcharged since my wife barely drives it 6000 miles a year and it is 95 aH instead of 92. Also I do not think the Macan knows how to compensate for the life of the battery since the original battery was depleted.
Regardless I will be keeping a close eye on it with my multimeter.
Just got the car used. 2016 Macan S. Needs a battery. Too bad I did not know that prior to buying it. Still has the original varta with mid year 2015 stamped on battery post.
Put a non BEM code battery in, which I have read that almost all in the US do not have that code. I followed forums, I spent hours researching, and while it accepted the codes, when I pressed send, I got an error that it was rejected and to try again. I even tried to put the original varta BEM code in and got an error. I tried this about 10 times, and nope, would not take, said try again.
Did not register. Car started and runs fine! I am going to send this POS scanner back because this is the only reason I bought it. Anyone know if it works? I have heard no confirmation or have seen any videos of anyone using the POR v2.0 successfully.
No, the one I removed was a 5 year old original OEM porsche varta with BEM coding. I put in a die hard H8 95aH 850 battery that by spec is identical. No BEW was a pita so I used numbers off internet...looked like it was taking data until I sent it...forgot the message but it said failure and try again or something like that. Tried is 3 times. Then I used the original old battery data....same thing....fail try again.Is the battery you used the same mAh as the one you removed?
I also replaced mine last month, after exactly 7 years. Replaced it with a DieHard H9, size fitment confirmed by @Teddis, so I went with that size too.
Registered battery immediately with Launch. Went smoothly.

This is the icarsoft POR v2.0, and the option is in the menu as it prompts me, but then fails. Is this thing indeed a POS? I am gonna get the autel you have. thanksThe iCarsoft POR II can not perform battery registration.
This has been discussed many, many times in various threads.
Research this again in this forum and you'll find I am correct. I too own one of these (iCarsoft devices) and have replaced it with an Autel MaxDiag MD808 Pro,
for this very (battery registration) reason(!!!).
Make sure you have POR V2.0 and not POR II - obnoxiously confusing.This is the icarsoft POR v2.0, and the option is in the menu as it prompts me, but then fails. Is this thing indeed a POS? I am gonna get the autel you have. thanks
Has anyone absolutely verified that the POR V2.0 works for battery registration? I just bought one feburary 28,2022 and can tell you that while it is in the menu, I have attempted 10 times, and even used the exact varta BEM code from old battery and I got an error that it would not take it and try again. I contacted icarsoft and got no reponse. I am going to return it for a foxwell.
WOW! I just did it and it worked! Used the original varta part number and had to change the 650 part of other code to 651 and it took it! Thank you!!!!!!!!!!Make sure you have POR V2.0 and not POR II - obnoxiously confusing.
Yes, the iCarSoft POR V2.0 does work.
Select service, BMS, and 911 as the vehicle (sounds crazy, but US tech confirmed it and it works). If you choose macan - you cannot enter enough characters for the part number and serial number and it will fail to communicate with the vehicle.
Also - the numbers serial numbers etc are not important to function correctly - for tracking and warranty purposes. What is important is AGM under type and amp rating.
The update is EASY! Mine was already up to date, but just plug it into your computer with the inluded USB cable, but first get the most up to date firmware from the icarsoft website. It is pretty much plug and play for that!Thanks to this thread I just purchased the iCarsoft POR v2.0 from amazon.com for $145. Now I have to go figure out how to update it before using it.
I wonder what amp size the dealer would replace he original 75 amp battery with? Could the owner request a larger amp battery?Everyone seems to always be referring to replacing either 92Ah or 105Ah batteries in their Macans...but my OE battery in my '17S is only 75Ah. It's size H7 (94r). In fact, it's the exact same battery as in my wife's '15 Q5 2.0L/ 4 cyl. Anybody know what's up with that? Why is my Macan battery so small compared to others?
I can replace with a like-for-like battery but with 80Ah rather than 75Ah (Exide, Bosch, Interstate/ Johnson Control/Clarios brands)...or should I be upgrading to a larger battery all together? H8/49 @ 92Ah or 105Ah?
May be this explains why my start/stop stopped working after 20K miles.
