Which battery for 981?
Discussion
2014 2.7 PDK - came up with "Low battery - start engine" today after 4 days in the garage.
Might be the beginning of the end for the battery? It seemed fine after a 100 mile run.
Last used Saturday for a daytime 50 mile run. Prior to that, not a lot over the Christmas break.
As for a new battery, if it needs one, what would be recommended? Car's under warranty so I need to be a little careful it's a decent one my OPC won't snub.
Thanks for your suggestions.

The 981's three standard 12v sockets switch off after 30 mins approx. I timed the one under the dash as I have my dash cam plugged in there and wanted to check how long it would record when parked up, key out.
No idea about how this affects charge going the other way TO the battery?
Thanks for the info so far. It seems to be behaving itself but I'll keep an eye on it naturally.

My dealer principal has confirmed "Batteries are not covered by the warranty as they are considered wear and tear, the cold will affect the battery but you could also have a cell down which would cause this problem, do you have a charger or conditioner for the battery? If not we could carry out a battery test for you."
The car is kept in a warm garage. I'll just keep an eye on it and if it fails I'll replace it. Or does anyone think the make/model/capacity of an "aftermarket" battery (shock, horror) could really enable Porsche to defend a warranty claim? What fault could be put down to the battery? Melting wiring? An overworked alternator? I can't imagine.

To dealer principal Leics OPC today:
"Am I correct in saying the 981 armrest 12v socket can detect a battery conditioner plugged into it and if it does it stays live to charge the battery?"
Response:
"Yes that's the one to use alongside the Porsche battery conditioner that Glenn here in parts can sell you."
I've seen CTEK MXS 5.0 for £60: http://www.ctek.com/gb/en/chargers/MXS%205.0
...and XS 0.8 for £35: http://www.ctek.com/gb/en/chargers/XS%200.8
The latter is "...suitable for maintenance charging “normal- sized” batteries such as car batteries."
Add a 12v socket connector for £8: http://www.ctek.com/gb/en/chargers/Comfort%20Conne...
I guess the MXS 5.0 would be "more useful", but for what?

Since I posted this thread almost two years ago my battery is still alive!
What I did was to buy a Ctek 5.0 and extension lead, as here: https://www.amazon.co.uk/Battery-Automatic-Tempera...
Plus, a 12v cigar lighter attachment: https://www.amazon.co.uk/CTEK-CTE-56263-Cigarette-...
I believe the Ctek charger does a better job of conditioning the battery than a simple charger would do. It certainly seems to have breathed new life into my battery, now coming up 5 years old. I've used the Ctek 3-4 times in those two years when I get the feeling the battery is low, typically when not used for 4-5 days in winter time.
In March of this year I also had the "fan stuck" issue during a freezing 100 mile drive. This cured itself when I stopped for 10 minutes and simply turned the car back on after that time. Although under warranty, PGB would not do anything but make a note of this "intermittent" fault.
I think your issue is the sticky fan, not the battery, but naturally you'd think the latter to be the cause. After your 90 minutes, did the fan start working whilst driving or had you stopped and turned the car off?

When I last looked, design911 had the correct battery for my 981 advertised on their site. I took a photo of the top of mine so I could compare the part number.
When I phoned design911 the chap checked the item on the shelf and it was slightly different, so I'd suggest doing the same and phoning them. Battery has to be coded in I seem to remember, not just DIY connected.
Have a look here: https://www.design911.co.uk/fu/pt259_261_-cma81-cm...
There was no recall for the fan issue back in March. Many owners have reported having a replacement under warranty prior to this, but that may have been for a repeatable failure whereas intermittent faults aren't covered, even when you know it's happened, have recorded the odd clicking noise it makes on your dash cam, and you KNOW what the issue is and the remedy (replacing the fan unit).
