Since it's mostly about software - how about a firmware update for the iCarsoft POR II???

There are several of us forum members who own those units. Let's all contact Barnett Davies (email address?) and
let him know it would certainly be appropriate for iCarsoft to add battery registration functionality to the POR II units -
especially considering the Macan models outsell all other Porsche models.

Once we discover a device reasonably priced that will reset oil change nag screen & register new batteries....we need to know which specific batteries will work with the registration.
It is easy to find AGM batteries that will physically fit in the battery location & have = or better specs.
However, I wonder if these batteries will have a serial number that will be accepted?

For example the Varta battery may have a serial number with more or less digits vs. whatever battery we wish to replace it with.

I suppose a work-a-round might be to just reuse the serial # of the old Varta Battery or maybe add +1 to whatever the last number is? Make the Porsche computer think we put in a new Varta. Even though we put in a Bosche with more CCA?

Not sure how similar or dissimilar Porsche's battery registration process is to BMWs.

But I do have the distinct impression with BMW the battery serial number is merely to identify the battery. The technician is able to look at the battery replacement history of the vehicle and at least theoretically determine if the current battery in the vehicle was correctly registered. At least with BMW I strongly suspect the tool is not very fussy about the battery serial number, except possibly knowing how many digits it should have.

Can't say I know this for a fact, but I also suspect Porsche uses the battery serial number in a similar manner.
 
I'm sure you can find the list of "acceptable" batteries from PCNA.

I don't think the tool has much to do other than pass the info to the vehicle; meaning the tool doesn't accept or decline a battery; it's simply an interface. So as long as it has the required number of digits, as Wolverine stated, it won't complain unless the vehicle does. At that point the vehicle would pass that back as a function (retcode) to the tool, IMHO.

I've just sent email to Barnett Davies @ iCarsoft asking when the owners of the POR II devices can expect
the announcement of a firmware update that supports Macan battery registration.

Who will be next?

(strength in numbers!)

Who else had not paid attention to how their battery is doing, but is now looking at their cars battery voltage every time they drive their car. I can’t stop paying attention to my battery now. LOL
 
Off- but not too off-topic-

Just had my new untitled SE delivered to me and checking the battery it was down to 12.2 volts by sitting in the lot and not being driven- so the electronics as everyone knows slowly drains the battery.

My question-- since the Macan uses an AGM- my Ctek 7002 gives me a choice of charge modes. I assume that I use the cold/AGM mode for charging. Ctek says to check with the battery manufacturer to be sure which model is correct.

The owner's manual does not make it clear if only an AGM specific charger should be used- but I am assuming that AGM on the 7002 would be best.

Any opinions?

The OM on my CTEK 4.3 says the Normal battery program is:
14.4V/4.3A. Use for WET batteries, Ca/Ca, MF, GEL batteries and many AGM batteries. 41ºF–122ºF (+5°C–+50°C)

It also says:
Cold weather program 14.7V/4.3A . Use for charging at low temperatures and for power AGM batteries like Optima and Odyssey. -4ºF–41ºF

So I've assumed for our type of AGM battery the normal program would be correct except under 41 degrees.

Audi does the exact same thing, in that you use the Vag-Com software cable to register the replacement battery, and either enter the new battery serial number, or just change one number from the old battery, and it will take just as long as you don't change/mess up the registration formatting.

Which is exactly what I mentioned above.

It has nothing to do with the analyzer. The latter does not allow, nor verify whether a battery is valid or number is correct. It simply checks that it has the correct number of digits and passes this to the vehicle (if not you would have to update your analyzer every time a new manufacturer or serial number for a battery was issued). Alas we don't have anything near as sophisticated as a VAG-COM in Porscheland, but the approach is the same whether with iCarSoft, or Duramteric or other

I also read that in my instructions-- my question is really aimed at understanding if the Varta(?) AGM supplied in our Macans is closer to the construction and operational characteristics as that of the Optima or Odyssey AGMs then to the more commonly advertised AGM batteries found on most battery websites-- thus requiring the same charging protocol as the Optima or Odyssey batteries. The term "many AGM batteries" does not automatically have me believe that the Varta AGM is in the "many" category and should be charged using the Normal charging program.

That is not the voltage. That is the output of the alternator.

I would not assume that at all. Do some research through all the forums and see what the consensus is, what people actually use. Here's a thread where someone actually called CTEK


 
A couple of comments here from my experiences with CTEK, Durametric, Porsche and BMW battery changes. First, my CTEK is used in the "14.7V/4.3A" mode at all times with my MY 2015 Macan S with an Interstate H8 replacement AGM battery.. No problems whatsoever. Second, I have used a Durametric unit for a decade on my Porsches. A great investment for both diagnosis and clearing fault codes as well as annoying "nanny" notices about time/mileage maintenance messages. The Durametric unit does not do battery management and, from my discussion with Durametric support, they appear to have no intention of adding such a function at this time.

Third, as I have commented on this forum several times, I bought an iCarSoft Porsche V2.0 last spring because it was advertised to do battery management on a Macan. I got it, set it up, and it failed to deliver on the Macan, despite what Barnett Davies had told me. I sent it back and got a refund. I had my indie replace the original Varga and register the new Interstate battery ($400).

Finally, a comment on replacing BMW batteries, a much more transparent process than with Porsches. For less than $100, one can buy an OBDII cable and software to use with an old laptop to do the battery management on a BMW. With a tool program called "NCS Expert", one can "code" a new battery if is not exactly the same as the battery being replaced. For example, one may be going from a 80Ah lead acid battery to a 90Ah agm battery (that I have done). The program tells the ecu of the battery change so charging changes can be implemented appropriate to the battery requirements (prevents over- or undercharging). Then a program named "Tool32" is used to "register" the new battery. This records time, etc. of the replacement so that charging appropriate to the in-duty time of the battery is maintained for optimal battery efficiency and life. There is no need to look for any special decal or icon on the new battery. The only thing needed for this process is the Ah rating for the battery and if it is an AGM or lead acid battery.

It seems that Porsche does everything they can do to monetize everything they can to cause Porsche owners to go to their dealerships for service. Maybe not a bad business plan.

AGM supplied in our Macans is closer to the construction and operational characteristics as that of the Optima or Odyssey AGMs then to the more commonly advertised AGM batteries found on most battery websites-- thus requiring the same charging protocol as the Optima or Odyssey batteries.

I would not assume that at all. Do some research through all the forums and see what the consensus is, what people actually use. Here's a thread where someone actually called CTEK
So it would seem there's no clear answer as to whether our Varga OEM batteries should be charged at 14.4 or 14.7.

Grim, I did look at the thread you supplied the link to where the Rennlist member called CTEK. His actual post was "I called and spoke to the CTEK engineer directly. He said the snowflake is the appropriate setting for AGM batteries as they require higher amperage". That directly conflicts with the OM on my CTEK 4.3 which states "many AGM batteries" would use the "Normal" (14,4V program). So what are we to believe? The OM or their guy on the phone? And it looks like the OM language with respect to this issue changes a bit from CTEK model to CTEK model. The 7002 OM mentions nothing about any AGM batteries taking 14.4. So maybe the answer depends on which model CTEK you own? Who knows?

So I scoured the Varta website and could not find anything regarding the correct charging voltage for our AGM batteries.

Odessey's website seems to infer that all AGM batteries need 14.7: "The best way to charge an ODYSSEY® battery is to use an AGM specific charger. Chargers such as the ODYSSEY® Battery Portable Charger have the required 14.7 volts needed to properly charge your ODYSSEY battery".

And look at what Optima says about the issue:
https://www.optimabatteries.com/en-us/experience/2015/10/what-does-agm-mean-battery-charger.

Tried to find an OM for the Porsche charger on line but was unsuccessful.

Perhaps the answer is that I should attempt to use the CTEK only on the snowflake setting and only below 41 degrees?o_O

Shark-- I decided that Porsche would install an AGM battery that would be closer in design/quality to the Optima which has always portrayed itself as a premium AGM battery. 50/50 choice so I picked the 14.7V snowflake mode.

It is taking a good amount of time to get up to full charge-- sitting in a dealers' lot for weeks waiting to be sold has really drained this battery. I am detailing it in my garage which will take a few days so not driving it- great time to get the battery up to snuff.
 
Is the battery only $200-300?

Its Varta, right?


See the graph for AGM? 14.8 vs flooded 14.4

Sorry, yes Varta, not Varga. Good find. Ok, I'm now convinced 14.8 is correct.
