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 a, 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???
