I'm planning to store my M2 and use a not purchased yet beater for this winter.

I plan on doing the standard winterization process, covered garage, full fuel tank, fuel stabilizer, extra air in tires, carpet squares underneath tires, etc.

The problem I have is that the garage I have available to me does not have electricity to plug my battery into a charger. What is the best way to solve for this? Do I unplug the batter and charge it inside the house, will this cause coding issues when I try to re-connect in the spring?

will not cause coding issues if disconnecting. The only thing that will reset is adaptation and maybe clock, trip mileage, etc

I'm in the same situation. Does your garage have a light socket?

Unfortunately, no light socket, no electricity at all. But thanks for the suggestion.

Assuming cenz422 is correct, then there shouldn't be an issue, besides having to carry a heavy ass battery a few hundred feet to get it inside. :lol

Has anyone disconnected their M2 battery for a period of time and reconnected with no issues?

I disconnect the battery on my e46 m3 every winter and store it for 4 months. Note, the car is supercharged with a tune and I have no issues except for resetting my clock and car adapting to my heavy foot again.

Not a bad idea...will have to look into it a bit more.
