Found unsold '23 XLT ER: Battery implications from sitting 2years?

[RickLightning]

My question was rhetorical

The battery warranty is 8yrs or 100k miles. Just buy the damn thing if you like the deal.

For reference, I’m knee-deep in the car business. I bought my ‘23 XLT ER after it sat on a local lot for about a year. Zero qualms about battery health, and on a full charge during warmer months I showed 340+mi

The GOM isn't a measure of battery health.

Observed by itself, you are correct

Prior to a recent trip, my Lightning showed a SOH of 98.5%. During the trip, it climbed to 99.5%, and then 100%. It sat from April 2022 to May 2023 at a dealership.

The issue isn't reliability, the issue is capacity. That is that we know with certainty is reduced by sitting at 100% charge, it is also something that is reported on by the BMS and can be retrieved with a scan tool (to as much as can be believed).

Any component can fail, but we are not talking about failure.

I highly doubt that a sales dept exists that keeps batteries charged at 100%. Even then we’re talking what, 5% deg? And then read what Rick just said about his measured SOH read and how it changed. SOH isn’t a constant either - it can and will change +/- with use and balancing of the cells. One individual cell can short internally at any given moment rendering that module faulty.

Being in the know, repairing systems just like this on the daily, wouldn’t stop me from signing on a good deal for a leftover ‘23 provided the warranty clock hasn’t started. Stressing ain’t worth it.

So, still have the Lightning bug. In browsing around, I found a dealer in rural western Canada that somehow appears to have 2 unsold 2023 Lightning XLT ER's still on their lot. Although they don't have a heat pump, they have the 312 package that have the faster onboard chargers, etc. They don't have them advertised at a competitive price but I haven't called to ask a real price either. Was interested in your thoughts about what the implications were for battery health here. Presumed sitting on the lot for 2+ years and rarely driven and no idea about what state of charge they've been kept at or charged to. In a really cold climate and regularly -30 for extended intervals in winter. Would have to be a crazy deal to make it worthwhile and to justify shipping it across country, but wondered if the battery age/lack of use would be a deal breaker for you? Would still have full regular warranty.

Buy.
Just bid a low price. The dealer is going to want to move them.
Pretend you are going to finance them though, then pay cash.
The dealer will give you a low sale price...thinking they are going to make money off of you on the financing.

Get a low price, and do it!

That doesn't mean the battery won't be at 71% capacity in 8 years, instead of 85. Both still sufficient to maintain the warranty. Or worse, 68% capacity, so they swap in one refurbished module, bringing it up to 71%. Bam, meets the 8yr warranty. Let's not forget that 70% capacity is 225 miles, or more like 180 at 70mph.

10% capacity loss from sitting is 10% for the rest of the life of the vehicle. That 320 mile range is now under 300 from the day you buy it.

This is worst case scenario; where do you place the odds of this occurring? 10%? 90%? It's sort of pointless to talk about possibilities without probabilities.

The other part of the equation is the cost of the truck. For instance: is 10% off MSRP worth a 10% chance or your worst case scenario? I'd say no. Is 20% off MSRP worth it? Now I'm interested.

The about numbers are for illustrative purposes only. If I had to guess I'd say the odds of a barely better than warranteed battery after the warranty period is much lower than 10% no matter how a vehicle is stored.

My problem is that I have an itch for a lot of things. I think I have EV fleas. Or EVexcema.

Well, you have done it again. You got us all worked up .... what are you going to do?

Separately from the traction battery discussion above, I have the 312A Option 2023 XLT and I am very happy with it, other than the lack (so far ) of power folding mirrors. IMHO the 2023 XLT ER 312A has about the perfect mix of features.

As long as it was not sitting at 100% for two years, it should be just fine.

recommended long-term sitting is 50%

100% agreed. I wake up every day and get excited to drive mine to work.

I’m interested! Primarily because we just bought a 2023 platinum brand new . It was sitting at a dealership and had never been sold. It was a very good deal, or at least was much more affordable. We will see if it was a good deal in the long run. Loving it so far but hating the deep freeze I’m dealing with while waiting to get the various chargers installed.

I truly wouldn’t worry if you got a good price on the truck. The battery pack is guaranteed eight years or 100,000 miles. So if it failed 50,000 and you got a brand new battery I believe you would totally be ahead of the game, other than the inconvenience being without your truck for a couple of weeks

Wouldn't worry about HVB. Get a new LVB from dealer and be sure the BMS replacement has been done. Also, get ALL THE OTAs! Are tires ok? Heavy truck sitting around... Check for animal nests and damage undersides.

The longer you wait the bigger the itch get. No worries about the battery being dormant for a while. Have the dealer charge it to 100% upon your arrival.
Reset the history and look at the range.

Good point. Unless the truck has the new updated BMS and related OTAs the 12v will have reduced capacity. My 12v got replaced under warranty a few months ago even though I regularly kept it on a tender. I didn't even know it was bad.
