I have an upcoming trip where my truck will be parked at the airport for several days. Has anyone done this recently and how was the battery drain while the truck sat? Should I disable sentry? A little worried about turning sentry off but I know it drains the battery quite a bit over time.

Several days you can probably plan for a Sentry drain of 10%±n per day; but if you let the truck sleep, it should only lose 1-2% a day depending upon weather.

Here's someone who was away for eleven days and let the truck sleep:

Here's someone who left Sentry on (tho drain can vary wildly depending upon proximity to people):

And here's a longer, but earlier thread on phantom drain:

Yeah. Id turn sentry mode off unless your airport parking has ev spaces with maintenance chargers.

one thing I noticed while camping with no sentry the temp got down to 36 at night and wow! Lost 10% overnight. Battery conditioning will kill too.

it's automatic when temps drop. Can't control that function
Strange on all the Tesla's I have owned I have been in really low temps, and I never have had this problem. If the car sits the car sits. Even in well below 0F haven't had that problem. Sure the amount available is not there as the car/truck warms via usage. I think what one might be seeing is a large amount of not available vs actual loss. Might lose some in the inefficient warming during driving.

One time I didn't get that amount back because the car never warmed. It was -23F outside. The next supercharger warmed it. It gets really cold in Manitoba for some reason.

I am going to chime a resident expert on the truck @mongo to see what they think of this issue you had.

Ask me in the spring ?

General thoughts: 10% overnight is some other issue, undertemp protection shouldn't kick in at 36...
