I unfortunately don't have access to a power outlet in the garage I'll be parking my 991.2 over the winter months (roughly December through March, inclusive). I'm based in New England, so would really prefer not driving around the block to "charge" the battery as it would expose me to the nasty road salt they put down here (and I'm also planning to keep my summer tires).

Has anyone just left a car for 4 months without having trouble restarting? I feel like this hasn't been much of an issue on my other car (a Honda), but not sure about this Porsche.

Thanks!

Your best option is make sure your battery is fully charged then when you are ready to put her to bed disconnect the battery. It should be fine when you hook her back up in 4 months!

This exactly.

Can you take the battery out and store it in the house on a trickle charger? Also, correct me if I'm wrong, but don't close the frunk with the battery removed, rightt?

When I stored my car over one winter, I removed the battery and left in a heated basement without a trickle charger. Was perfectly fine when I installed it five months later in the spring.

I also removed the catch from the frunk lid so it could rest in a more closed position without having to worry about accidentally locking it.

Yes it’s important that battery is in temp controlled environment, drains fast in cooler temps.

Unhook the battery. It'll be fine. I've stored cars outside in the Minnesota winters like this with zero ill effects.

It's that time of the year again, and we will be getting a lot of car storage questions, but don't forget to stabilize your fuel.

New England winters seem more mild the last five years. Many 40's and 50's days. I used to park cars, have second sets of wheels, etc. Now you can almost drive all year on summers if you pick your days and have other cars. As for road chemical yes, but it's just a car. Which can be washed underneath. I'd rather take it for a drive every now and then over leaving it sitting for 4 months, but that's just me. I drive my 911 in the rain. I know some don't. If you really want it to sit I'd take the battery inside and keep it charged, as stated. Leaving the battery connected for four months will likely kill it, or at least reduce its capacity.

I have an external battery pack that is used to jump start cars. I wonder if something similar exists to trickle charge batteries (I kind of think mine can trickle charge).

In that case you could just hook that external thing up every 3-4 weeks (charge the external charger indoors somewhere) and then you could leave your battery in the car.

I'm not sure about this, but might be worth looking into.

Yes there is something. Google CTEK battery charger. They are smart charges that recharge battery to 80% or so then maintain a trickle charge to keep it alive. There’s more to it than that. I use it to store my BMW Z4M over the winter and now that I’m work from home due to covid I have three for all my cars to keep the batteries healthy. People leave them on for a year or more no issues.

And even faster in the heat!

That seems like a good alternative to taking the battery out.

If you remove the battery do you loose your settings?

I’m also in the North East in NH. If I were you, I wouldn’t let the car sit without a charger for four months. Either get the battery out and keep it inside where you can charge it or install a set of snow tires and drive it in the winter. It is a fun car to drive in the cold season with snow tires.
