Need info on long term parking & battery
I need to relocate my two summer queens for their winter nap to a non-powered facility.
Is there any risk associated with the battery going dead or the car having no connected power for 4-5 months ?
TIA

You will probably need to replace the battery if you leave it that long without disconnecting it. The battery might also freeze and crack. With the battery dead, you will need to open the door with a physical key and get into the battery compartment manually, too.
Also, be sure your antifreeze will protect down to the temps the car will see.
If you're good with that, sweet dreams.

Thus you have to be prepared to be able to open the trunk and get at the battery to probably replace it. Lead/acid batteries do not like to be deep discharged. While it might take a charge it will never be as good as it was when you put the car away.
If you disconnect the battery (and remove the battery) if you close/latch the front trunk lid you have be sure you can get at the emergency front trunk lid cable so you can open the trunk lid sans no electrical power.
Also, you pretty much have to be prepared to have the trunk lid closed. You might forget and close it yourself, or someone walking by your car will close it for you.
Also, during this time the car will be unlocked. You can probably open a door but the window glass will not drop.
Bad enough but then when you close the door the glass will be up and I don't know what this can mean when closing the door on your Turbo.
With my Boxster it meant the top edge of the glass hit the top rail and the sound it made had me preparing to be showered with glass fragments. However, as bad as it sounded (and felt) the glass never broke. Still I'd not risk this.
So I guess it is remove the battery. Be sure the emergency front trunk lid open cable is handy. Leave the doors unlocked and the windows down. Best if you can cover the car with a cover. I'd prefer to use the outside cover as it is more durable and heavier thus offering more "protection".
Be sure when you park the car you do not park it under water pipes or under a hanging light fixture. Avoid parking it where it might need to be moved to give someone access to some access panel to get at the building's plumbing, wiring, or whatever.

That's what I would do too.

FWIW, I accidentally left 991.1 GT3 with battery not unhooked and battery tender disconnected for almost 2 months (in a heated garage). When I came back and put the battery charger on it, it showed 75% charged and went to fully charged very quickly. My 2011 Cayenne would go to 50% battery within two weeks. I think Porsche might have built-in automatic battery disconnect of some sort into the 991s.
Anyway, I'd just disconnect the battery for up to 2-3 months and pull the battery and put it on a tender for anything longer than that.

I have stored my 991TTS for the past two winters (near Boston) in an unheated garage and no trickle charger. I prepare the battery by charging it to a full charge before storing the car. I then park it in the garage, open the frunk, and then close the car door so the window movement occurs. I then disconnect the negative lead from the battery and wrap it to protect it from coming in contact with anything else. I lower the frunk but do not close it all the way. I then cover the car. (There are a few other preparation thing I do too.).
Once this is done, the garage gets closed and locked. I don't ever touch the car until I am ready to bring it out for the spring. It is usually stored from Mid-November to Mid-April. I haven't had any battery issues, the car starts no problem. That first day I put it back on the battery charger to ensure its fully charged to start the season.
