Thanks in advance for entertaining yet another vampire drain post.
I will be leaving my 2022 Model 3 at San Francisco Intl Airport for 24 days in May. I've read through many of the posts in this forum about what to turn off (Sentry Mode, Cabin Overheat Protection; I don't have Summon on my car). I do not have any apps like Tessie or Stats installed. I will keep off my Tesla app while on vacation.
While I am worried that I could come home to a dead battery, it doesn't seem likely. But I'm a worrier. And of course I've read many stories of batteries dying.
I'm going to begin testing my vampire drain now. I've just turned off Sentry and Overheat and will check it for it the days we don't use the car.
But I still have some questions:
1. My understanding it that while the Tesla software update uses WiFi, their documentation states that on some occasions it will update though the cellular network. I assume it tries this if not connected to WiFi for some time. It this were to occur, it could defeat all the other precautions. Does anyone have any information on when it decides to do a cellular update? I assume there is no way to disable this. Also, I see that I can select "Standard" or "Advanced" for the Software Update Preferences. Mine is Advanced. Is there really an advantage to setting this to Standard (but I will just in case).
2. What about the low voltage battery? I don't know if my car has a lead acid or lithium one, if that matters. I read that "some" 2022 Model 3 have Lithium. Do I need to worry about it on what will then be a 10 month old car?
3. I read a story about someone whose battery died after leaving the car unused for a few months. It was so dead that it bricked the battery and he had to replace it at his cost, which was very expensive. Is this a real thing or just some very rare oddball event? If for some unforeseen reason mine goes completely dead, what happens? Will Tesla's mobile service be able to start it or would they need to tow it?
I could take my 2012 MB ML350 instead. But I think that would almost certainly be dead by the time I got back. The upside is that I would just need a jump from AAA or bring along a portable jump starter.
Thanks for your input.
