Lightning Work Truck - Battery Age Analysis

[DemandingJay]

Saw this video from Trucked Up EV's. I really enjoy his content and, especially after watching, feel even better about my truck.

I have had mine for 15 months today and rolled over 32k miles...I absolutely love this thing and it feels like it'll take care of me for a long time.

This is based on the numbers given by the OBD2. I’ve heard people say the numbers of state of health on those things doesn’t mean anything because it isn’t accurate. I’d like to know if that’s propaganda. If so I’m very excited.

I am driving mine mostly granny style with rare moments of insanity. Charging has been very easy. My SOH has been going down linearly. 20K, 3 years at 97.5%.

If not via obd2 then there’s got to be a way get at battery health somehow. Forscan? FDRS?

I've heard the same, but only have access to the OBD. Mine is 26 months old and still showing 100% health as well.

“

• If you simply want a ballpark idea of how your high-voltage battery pack is holding up (e.g., > 95% health, or noticing a drop to ~90%), then yes — using a good OBD‐adapter + correct PID list + app is very useful for the Lightning.
• If you want a precise forensic diagnosis of pack degradation (exact remaining kWh capacity, individual module/ cell deviations, prediction of remaining life, whether warranty threshold meets factory spec, etc.), then you should treat the OBD reading as one tool, but not the finalword. A factory diagnostic tool/service may reveal more detail (e.g., internal pack capacity testing).

It's not exact since there are fluctuations in temperature but if you knew the on board charger efficiency, have a station that reliably reports power in and use OBD to get charge level, you could use math to get a pretty good estimate of pack health, especially over time. But who wants to do that???

My truck has over 100k miles and I got it in June 2022 .FDRS is reporting a battery health of 97.5 %

I was at the dealer on Saturday and the report that Ford gives the service advisor states that the high voltage battery health was at 96%. The truck is 42 months old with 24,303 miles. Is this appropriate or am I mistreating my battery? I rarely fast charge and only charge to 80% unless I am going on a trip.

Pretty normal. You're doing fine. Truck's doing fine.

Initial degeneration the first bit of its battery life, then settles down for the rest of its life. Degeneration is non-linear. Keep using your truck the way you've been using it.

Age is factor in battery health as well. Even if you don't drive it, as time passes the battery will have some degradation. I agree, that seems in the ball park for normal. The only thing I care about is how much energy I can crank into the battery. Here's what I have prior to my road trip this past winter

That puts me around 96.6% of stated 131kWh initial capacity. Sadly I did not take a reading until long after I bought it. I think I was around 128kWh last year. At 53k miles and 3 years, loss is around 1.5kWh per year. I'm very happy.

If anyone is curious, my 12v battery is original a well. I'm surprised it's doing this well here. My Subaru ate 12v like they came out of a Pringles can.
