Leaving Lightning unplugged for a couple weeks

[LariatLarry]

Like at an airport parking lot, with about 40% charge. Will it lose any of the charge?

No, it'll be fine and that's a good level for it to be at while you're away.

I believe best practices is to store it at 50% or less for how long I have no idea. Perhaps someone with better information will post.

Parked a couple weeks .... VS. Storage.

What are the expected temperatures for the time period it will be sitting?

That must be where I remember the 50% from!
So for a couple of weeks it doesn’t matter??

I’m glad the man is here to help!
Obviously, that would be you

My MY23 was one of the ones that had a hold on delivery after the fire at Ford in Feb '23. It sat at the transfer yard for 9 weeks at 70% soc. I've had zero issues to date. I think it dropped 3% over the 9 weeks it sat in the cold in Toronto.

Right. Less than 30 days it's fine. And 40% is fine vs. 50%.

I do believe the Lightning will into a deep sleep mode of sorts.
Scared me last time that happened, as it took a while to fire up. I thought I had killed it somehow, but all was good.

I believe the recent released charts would suggest you bump up the 40% to 50% during this uncertain winter weather.

This was a complete shock to me and I have yet to read why this is happening.

mid 30s at night, 60s in the daytime

zero issues, I do this frequently.

I just had mine sitting for almost a month while traveling, temperatures mostly between 40 and 70 F. Didn't lose any noticeable charge.

On a related note, I store my truck in an unheated but below grade garage for most of the winter. It rarely if ever goes below freezing, usually staying in the mid-40's. The post above from the Ford manual recommends disconnecting the 12V battery. However when I stored it last winter, I left the battery connected and on a Noco battery tender. Seemed to work fine and SOC was still at the 50% I stored it at almost 4 months earlier.

Which leads to my question. Is one method clearly better than the other, or does it not matter?

I left mine for over a month at SeaTac with no problem, about 65% charge. This is how I know that the guess-o-meter is completely goofy, it said that I wouldn’t make it home without charging (it is fairly flat from Seattle to where I live).
