The API shows a value named "battery health level". What is it?

These are from whenever the car was last awake. Interesting to watch while preconditioning or charging.

I confirm, just check a few minutes ago, after a 30 minutes pre-conditionning (via app) the min cell t°went from -6°c bat t° to +2°c (outside -8°c from cold -12°c night), so it works and I recover full speed recharge capabilities (no blue restriction on the charging page) but at those outside temp, 30 minutes is not enough to recover full REGEN CHARGING. Still have a blue mark on the battery shown in cluster + mesage). Then I recharge with my home 11kw charger from 54% to 69% (about 1hr 10min) and now bat t° has peak at 13°c. All good to go
Bottom line, with cold (Canadian like) winter we need to know those number to maximize range before leaving on a trip. And if I don't go too far I think it is a good battery care habit.

I just came here to look at this type of thread. I took my 2022 GT with 50k miles in for a hood thing and they told me they were replacing the battery. They told me that some VINs for 2022 were getting replaced but could not/would not tell me why. I just checked the link above and it says my battery is at 91.4%. How would that compare with others around the same year or miles? Anyone else have the batteries replaced without reason? Any hypothesis as to why they are replacing? Thanks!

I am at 95.9 with 22 AGT with 24k miles.

My 2023 Touring starting throwing "Drive System Warning" and Lucid replaced the battery. I had 22k miles. The SC said that it was a "Module Imbalance"

Before replacement, the Battery Health was 95.6% .. it also said I had an 84kWh Battery Capacity

After replacement, the Battery Health was 99.9% and 89kWh Capacity. I'm back to 384 mile range at 100% SOC

Our car: 2022 Dream Edition Performance
31,709 miles
HV battery pack and rear drive unit replaced in mid-2024

API data:

Field 4, capacity_kwhr: 106.68999761529267
Field 11, battery_health_level: 94.3000014051795
Field 16, battery_cell_type: BATTERY_CELL_TYPE_SDI_50G (2)

This confirms the HV pack was remanufactured with the Samsung cells (SDI) as in the original 118-kWh pack.

Assuming the nominal 118-kWh was used in this calculation, it would indicate the battery currently has about 90.4% of its original capacity. Yet it shows a battery health level just over 94.3. Does this mean "battery health" is not the degradation percentage, or the 118-kWh nominal is not the pack's actual capacity?

My almost new 25 Pure (Built October 2024, bought at the tail end of December) shows a battery health of 96.5 - kind of annoying…

I wonder if they just want the battery back to examine it for testing, engineering validation on degradation.
