Charge O Mat problem solved
Hi all, I have an update you may find useful.
My charge o mat was “locking out” after 30 minutes of charging despite my following the prescribed procedure that had worked before.
I took it to one of my local dealers, the SA said they were aware of this issue and had already looked into it and prescribed a new procedure which seems to have resolved the issue.
Here is the procedure:
1. Car ON and engine running
2. Plug charge o mat into 12v adapter
3. Plug charge o mat into wall socket and switch to your appropriate setting
4. Turn off car (I waited about a minute before doing this, although I was told I don’t have to)
Just did this now. 1 hour later, still charging

I wouldn’t be starting my engine during winter storage in order to engage my charger. Repeated starts to just start charging is very hard on the engine. Using the same charger as you, I just turn on the car without stepping on the brake pedal so it won’t start. Then turn on the seat heater so there is an electrical draw. Then put the charger into its charging mode and wait for it to get through the charge state analysis. Once it does that I just turn off the ignition and you are good to go until the charger drops off line in 1-3 weeks.
I suspect part of the issue for me is AC power drop outs here that cause the charger to cycle and get tripped out.

My 2020 keeps dropping off the charger at random intervals when the battery is fully charged. Doesn’t do it when it is really cold where the car is at, but a royal PITA if I wanted to leave it for a long period. Been having to restart the charging process every one to three weeks while stored. If it drops out after just a few days then I leave it to the weekend before restarting. Frankly with many Porsche’s being stored during snow months, I am shocked with how bad this portion of the execution is.

I always find these threads interesting. As someone from California, I have never in 40+years of life had to use a battery maintainer. I don't think I could live somewhere, where I had to park my car for the winter. I would probably convert to something cool like a retromod UNIMOG or big *** lifted 4x4 with the all the outdoor goodies like a winch, lights, etc. It must be hard looking at your baby in hibernation mode. It would depress me.

i am one of those guys that grew up in California then had enough and got away before things got too bad in my area. Trade off was a great place to raise kids, but too cold in the mid winter period to drive a car very fast…..lots of trade offs in life.

^ I sometimes gripe about the cold winter, but to me it’s just a part of life.
Some day I will move somewhere warm, I suspect. Probably not California, but…..who knows?

I don't disagree with you about CA and the thinking out here, but is it really better in TX? For some things, sure, but others, I'm not so sure... I'm a firm believer that there isn't a place without its issues, it's more about how much we're willing to tolerate. I def won't be out here full time when I'm ready to wind it down.
Back to the topic - what is the max one should leave a car for without a battery maintainer? And at what temps does it make sense to use a battery maintainer? We're in the process of buying a home in the desert where it occasionally gets to freezing temps at night, but high 30s low 40s are the norm during the peak winter (I know, nothing like the East/Midwest regions). It'll be a second home for a while and while my 992 is currently my DD, it may spend time at either location for several weeks without driving it.

Car batteries are expensive enough nowadays that I think it's worth using the maintainer full time. Hook it up directly to the battery or charging terminals using a quick-disconnect connector of your choice. I use 25A Anderson PowerPole connectors myself, but there are plenty of other options.
We will have to get into the habit of plugging our cars in soon enough anyway, might as well get a jump on the trend. My guess is that it will probably double the battery life.

^ Not sure I agree with this entirely.
Plug it in full time?
If you don’t plan to drive your car for weeks, then of course plug it in.
Otherwise I don’t see how that is necessary

After a lot of trial and error I found the easiest, best way to connect the Porsche battery maintainer is to connect directly to the battery and have the socket right there in the front trunk. I bought the Porsche part for this and had the dealer technician cut off the alligator clips, solder eyelets and cover them with shrink wrap, then connect directly to the bolts that connect the battery cables to the battery. The socket lies in the webbing on the right side of the front trunk. I think they charged 1/2 hour of labor and for me it was worth it. Very neat installation. Saves all these gyrations that are so frustrating to fool with.

This method didn’t work for me
I will have to continue plugging directly to battery for now.
