I’m wondering if there is a good way to check the battery health? I have used recurrent for my previous EVs. But it doesn’t work with lucid.
 
After 3.5 years and over 20k miles my battery health shows 93.6 but my kwhr capacity shows 105.8 kWh which assuming a 118kWh original capacity implies a 10.5% degradation. Not sure if that shows a discrepancy between battery health and capacity, but in any case I guess a 10% loss in 3.5 years isn't all that bad. Interestingly it also shows a range of 429 miles which is also the number I consistently get using my SOC and Miles showing on display and doing that calculation. Pretty sure that calculation of 429 miles is not accurate.
 
Here is my battery degradation in five months since brand new:

Field 11, battery_health_level: 97.50000145286322
 
When my AGT was brand new, the 80% SOC was 362 miles. It’s now at 360 for the same 80%.
 
I just checked min and it's - battery_health_level: 96.40000143647194. I just got it 3 weeks ago. Is this a bit low for a car that has 767 miles in 3 weeks?

I've heard that the number returned by the API is approximate, and that an accurate figure for battery health would come from Lucid service.

This is correct, and it even says so at the top of the page.

2022 GT with 60,000 miles and batteries replaced a few months back.
