I've stopped worrying about flat spots - the thumping goes away after a few miles

What he said...very true!

I agree about tires not flat spotting. today's tires just don't seem to have these issues. I leave a couple sports cars sitting through the Wisconsin winters over the last 15 years and I've never had a problem with flat spots.

I too am about to leave my M3 in a garage for six months over winter - in France.
I do wish to leave my Sentry Mode on while the car is in a garage and plugged in.
As the comments so far are from over 9 months ago I wonder if Tesla has provided any more information on storage, especially with Sentry.
Will the regular drain and recharge cause any degradation of the batteries?

Where you are storing it, do you anticipate having people walk by it daily? If so, and you get multiple sentry entries per day, I could see the drive filling up quickly up during its storage period. Therefore, you will either fill up and stop saving new files (v9) or overwrite old files, losing the old files (v10). In either case, you would lose events. So get as big a drive as you can, or...if you want something more foolproof, get an aftermarket dash cam with cellular connectivity options.

Set it to charge 50-60%. Degradation will be very. very, very small.

Sounds like a great application for Tesla-USB on a raspberry pi that will upload the clips to a server, then you can monitor remotely and never run out of space

If it is anything like S & X,

Mine will be outside (covered) for month of January in northeast. Wondering if cold winter weather will affect battery and if there is anything I can do about it

Don't do that. Multiple reasons. All battery related.

Best to keep it in conditioned garage, and absolute must to have it plugged into a high powered plug, such as a HPWC at the max rate the Model 3 can handle.

See discussions about dendrites in cold weather.

The car will not charge a cold battery, you don't have to worry about dendrites. They only form when charging a battery below freezing, which again, the car will not do.
Many of us do not have the option of a garage, if we did than of course we would already be storing it in there.

I stored mine for 4 months in my non air-conditioned garage in Scottsdale this summer. Highest temp I saw in the car was 95 degrees.
I charged to 80% and left it plugged in at 50% recharge level. It took 7 weeks for it to show 50% charge on the phone app. I could tell no difference, except for the dust, with it when I got home. Tires might have had a small flat spot that went away after 10 miles.

What happens if you turn it "OFF"? Does having it plugged in still maintain the batteries?

"Power Off" requires that no other use of any other energy using component of the car follows selection of "Power Off"

My technique to properly confirm a true "power off" has happened:

1. Sit in the car and ensure the HVAC system is "on",
2. Select the "Power Off" AND:
2a. Start a timer with your phone..
2b. ...while you DO NOT touch any other control and just sit there (do not touch the brake or accelerator/do not open the centre console lid/do not fasten a seat belt/do not move in your seat to set off any seat sensors/do not touch anything that would use power)...
2c. ...wait for the HVAC to shut down and then about 90 seconds later...
2d. ...you will hear the tempurature blend door within the HVAC assembly shift to a null position.

When you hear that final noise come from the HVAC system, then a true "power off" has happened.

Hope this helps.

Parked my "Y" 21 days ago, battery has only gone down 4%. I did not turn it "OFF" because I have to move it once in a while.

Down 24% after 80 days. Now on trickle charge sitting at 49% since March 1st.

If you guys were wondering how much it cost to keep your battery a float @ 50% while in storage, here's what mine has cost me so far this month. Not even a dollar yet. It will probably be like $1 by the end of the month.

The actual power consumption is a bit more than the

APP shows because it doesn't take into account the 50ma ( 2.3 Watts ) draw the charging cable takes to light those 5 LEDs. My monitor is reading 6.2 Kwatts so 85¢ so far actual cost. I will edit and update this post until the end of the month.
