What bad can happen if a Lightning sits for 6 months.

What bad can happen to a 2023 Lightning if it sits outside from 1/21/23 to mid July?

The truck has 100 miles on the odometer but was charged to 100% before parking...

It should be stored at around 50% charge, not 100% even though 100 is actually around 90. Storing the lithium batteries at high state of charge isn't good for them.

The owners manual actually states the procedure for long term storage, whoever did this didn't read it.

That being said, how much damage it really did is hard to say. Plus you've got an 8 year 100k mile warranty but from the sounds of it most people here aren't going to keep theirs anywhere near that long.

I Would be most afraid of critters. They chew on anything and everything.

Find someone with proper equipment to read the battery’s state of health. But I’m not sure if sitting like that skews the calculation or not.

You could find that rats took up residence in the car and ate your engine harness. Then wind up with 35k in repairs that your hope are covered by insurance (State Farm did for my Porsche) … and wait months while they manufacture new parts. Make sure its inside and you have no critters

Engine harness?

It's on an open paved lot...

RE: Pioneer's comment (didn't quote for some reason)

Imagine, if you will, that other things use electrical wires. Our truck might have a few of those .. and that rats may not know it's not an engine harness and eat it anyway

Regular application of Simple Green seems to keep them out, or mothballs. If you forget they will move right in (on a Porsche). That said, I'm not sure you can keep them out of the Lightning if you have that problem and they find the wires tasty (made from sustainable products, etc.). Still, I definitely have that problem here and they haven't chewed on the Lightning yet .. of course it hasn't gone through winter yet. Depends on how warm they find the truck as well .. they like a place to nest when its cold out .. especially one that has food lol.

I was wondering the same thing about my 12v LVB.
My truck is a mannequin that sat parked 6 months before being put up for sale. It only had 70 miles on it when I bought it. Dealer told me they were holding it for a customer and they barely used it for test drives. Customer backed out last minute and I had a chance to buy it.
Last week I received the famous "low battery" message and had the battery checked out at the dealer but they say 12v battery is at 90% SOC and it's still good, but I'm a little worried the 12v battery will fail sometime soon.

100% for long time would hurt capacity. The ER battery is 143kWh with 131kWh usable, but most of 12kWh should be used as low SOC. You'd better have technician check the capacity.

Many years ago I had a laptop that was always on charger used as a desktop. After 2 years the battery was dead, cannot hold any charge at all.

100% long time is next to 0%, 0% for short periods would hurt battery badly.

I used to do that and got the same result. But I discovered in laptops with removable batteries, you can run the laptop on AC without the battery (you lose the effective UPS functionality, but I hooked mine up to a real UPS). I put the battery in a refrigerator door compartment at about 50% charge, loosely wrapped inside a Ziploc bag (not sealed) at about 45 deg F on the door at ~50% charge, took it out ~every 6 months, let it warm up to room temperature before unrolling the bag, and topped it off to ~50% again. Next to no capacity loss for years kept that way, and the battery worked fine when I traveled. Unfortunately, these days most laptops do not have removable batteries. IIRC, with HP and Lenovo laptops, one can set the maximum state of charge desired. So you could run it a max of 50% SOC. The old laptops both charged the battery to 100% on AC and cooked the battery from processor heat at the same time!

I doubt you would have any issue with it. While not ideal, it was only 6 months. Wiring is not open like it is in ICE - that said, rodents seem to find a way in infested locations. In an open lot, it is unlikely. I'm guessing this is on a dealer lot? If so, have them warranty against potential rodent damage for a period of time. Also, have them show you the battery's health (I would expect it to be at 100% still). Then buy it and drive on.

On a positive note, it passed the self-ignition test.

Thanks. This is close to the situation that I'm trying to describe...
