Most would think the same as you. Unless they have enough experience to know otherwise. I've had 12 Porsches and most say in the garage all week. So I learned. If you leave it sit for days most every week, you'll be lucky to get 3 years out of your batteries. The battery in my 944 died in 2 years of weekend use.
Since I started using a battery maintainer, my Porsche batteries have lasted more than 6 years, and I sold or traded b4 having to replace them. The battery in my 2017 991.2 911 Turbo is over 5 years old and still going strong. Sulfation is a common problem, if you care to research it. It's not much work to plug in my CTEK maintainer, so why wouldn't I? .

This will be the second time I've had to replace the insulation under my hood. I am open to suggestions as I've tried several rodent deterrents but can't keep these mother f#(ers out of my 1940's dirt floor garage.

I have gone 2-3 weeks on both Porsches, but now that I see how much a Macan battery replacement costs, I might start using the Porsche tender I bought a couple years ago.

I use the cigarette lighter as it is convenient. You need to get it hooked up while the power is still flowing in the car after you park it. Yes, you can use the under hood battery connectors. Their benefit is if the power source goes out and starts again, so will your charger. This is not true if you use the cigarette lighter. The drawback is the inconvenience of the access. You can go to the battery itself for charging, but access to it is nearly impossible.

You can see the negative post with the (-) symbol on the top and the positive post is above the seal on the cowl under a protective cover (the cover is opened up in this picture.)

You can turn the car off first. The electronics keep flowing for awhile so you have time to get out of the car and collect your charger and plug it into the c. lighter and then the power source.

My Audi sits at the airport for 4-5 weeks at a time. It always starts right up. I believe the systems go into some sort of hibernation, because my radio has to restart itself. No settings are lost though. Also the battery is the original 2014 factory supplied. Amazing

Your vehicle sits outside at DEN in the winter? Wow, that battery must have been tested with some cold winter nights...

Will see in a few weeks what happens after 5 months of the battery being on a CTEK tender, hooked up to the front battery terminals, doors locked and alarm on, and inside a garage that can get quite cold. Fingers crossed.
