For those of you that do store your cars for the winter, I’m curious about all the comments regarding a battery tender. I’ve always pulled the battery completely (not in a 911 mind you) and stored it indoors. Is there an advantage to using a tender?

The advantage to a battery tender, ie: Ctek, is that you don't have to pull the battery. Simply hook up the tender to the battery and walk away. Battery enjoys the best possible treatment being fully charged for the entire winter without fear of overcharging. No battery could ask for anything better.
I worked hard for my somewhat rare, low mileage, mint cond. 997.2 6 sp coupe. I put on about 1k miles per year. I just can't see taking a work of art that was
laboriously designed and perfected by fellow former cheesehead Grant Larson and run it through salt and gravel. Just my opinion, but people who do are
morons. There are plenty of lesser cars to run in the salt and do donuts or whatever it is clowns do. Am I being too subtle?
Anyway, there are a number of good articles available by Googling "Storing My Porsche".
Completely agree, this is me too. Worked too hard to lose it to silly abuse. I agree on driving it as much as possible, but I sure don't abuse the car through weather or roads. I do ring the bell (7000rpm) each time I take it out, however - for the 1500 miles a year I get to drive it. My kid takes priority .

On this note, don't buy the Porsche version of Ctek as it's literally a Ctek.
This CTEK combination works really well, and the idiot lights on the plug are reassuring - if it pops out or is not seated in the 12V socket you can see immediately. Under $100.

On top of that, not breaking your back to yank out that 40 some pounds battery out of the car. CTEK is the way to go. Don’t be cheap.
^^After connecting CTEK terminal connectors to + - sides of battery, you can re-install battery cover and route the CTEK connector just outside the cover - The CTEK power cord can route under hood and snap in place and hood can be closed without interfering with seals when hood is fully closed. This makes it easy/simple/handy to disconnect when you want to drive the car and then re-connect. (When you take the slack out of the CTEK cord it doesn't interfere with the seal)

Thanks for for the feedback in the CTEK. I’m not worried about the cost of it as I think they’re a great solution. I was more interested from a fire hazard perspective. I’ve heard of bad outcomes with batteries on a tender for long periods and was curious about the collective experience
My experience has been nothing but positively brilliant. I have three units, use them on 2 cars and for batteries pulled out of boats and lawnmowers during the off season. I managed to get 8 summers out of a lawn garden tractor battery that spent time during the winter months on a Ctek. Prior to the Ctek I was getting maybe 3 seasons out of a battery. They are a simply a must have for the maintenance of any battery that goes a prolonged period of stagnant time. Unless you prefer to buy a lot of batteries, you gotta have one.
I have had excellent results with a 1.25A Deltran Battery Tender purchased in 2008. Still going strong on a 6 year old H7 lead acid battery.
I have learned to trust its maintainer function and place/leave it on the battery tender if not anticipated to drive the car within 2-3 days. This is through alligator clamp connection as I didn't have the post terminal connection wiring when replacing my original H6 Interstate battery in a mall parking lot one evening. Lack of trust is why my original battery only lasted 5 years.
Man...I know I'm old but none of this makes any sense to me...I bought the car to drive it not put it away for 4 or 5 months. I'll worry about the stuff that might go wrong when that stuff does go wrong and so far after driving the car in snow, sleet, rain and all kinds of bad weather for 5 years and it's now 12 years old with 90,000 miles it seems she's none the worse for wear. I drove all of my 911's (4 of them) just like that and no issues.
Been using CTEK on my Porsche's for 8 years and they stay on the car all year to maintain battery.
Never any issue.
I wouldn't trust inexpensive maintainers.

I will use pictures, this is why:
Car was destroyed after 1 season. Rim #2, tire #3. Not scared of the snow....scared of destroying cars I care about. (Happened on Long island Expressway during snow storm)
