I am a new Model X owner (2020). The video at the website said to keep the battery topped off all the time. I installed a wallcharger in my garage. After doing this for a week, my car notified me that doing that would shorten the life of my battery, so I stopped. I don't drive a lot--just run errands around town, mostly--so I have only needed to charge it every few weeks.
Yesterday, Tesla sent their Winter Driving Tips out to owners, telling us to keep it plugged in to keep the battery warm. I have noticed that the battery drains faster in cold weather, of course, but WHICH IS IT? Keep it plugged in or NOT?
If I only drive a few miles a day--and some days not at all--will it ruin the life of my battery? Or not...?
Which is it, Tesla?
