If you own or are shopping for a Cadillac Lyriq, you’ve probably heard about **battery state of health**, or noticed the battery capacity readout in the vehicle’s info screens. For an EV where the battery pack is both the fuel tank and most of the car’s value, understanding Cadillac Lyriq state of health (SOH) isn’t optional. It’s how you protect your range, your wallet, and your resale value.
Quick definition
On a Cadillac Lyriq, battery state of health is essentially a comparison of the **current usable battery capacity** to what the pack could hold when it was new. In simple terms: 100% means “as-new,” 90% means you have about 10% less energy storage than day one.
What “state of health” means on a Cadillac Lyriq
All modern EVs track the high‑voltage battery’s **state of health (SOH)**, but Cadillac doesn’t always use that exact phrase on the screen. Instead, Lyriq owners will typically see **“Battery Capacity”** in the Vehicle Status or Vehicle Information app in the center display. That battery capacity is your real‑world state of health.
- 100% battery capacity → The car believes the pack can store essentially as much energy as when new.
- 95–98% → Mild, normal early‑life degradation; you may not notice any range difference.
- 90% and below → Meaningful loss of range; worth digging into if the car is only a few years old.
- 70% or lower → This is the zone where OEM warranties usually step in on EVs; it’s also a red flag on an out‑of‑warranty car.
Think in range, not just percent
If your Lyriq originally showed ~312 miles of EPA range and the battery capacity now reads 92%, you’d expect roughly 8% less usable range in similar conditions, something like 285–290 miles on a full charge.
Where to see Cadillac Lyriq battery health in the car
Cadillac quietly did something very consumer‑friendly: they surfaced the Lyriq’s battery health right in the infotainment system, instead of hiding it behind dealer tools. You’ll typically find it via the **Vehicle Status** or **Vehicle Information** app on the center display, depending on model year and software version.
- On the center screen, tap the Vehicle Status or Vehicle Information app icon.
- From the overview screen, look for cards or tiles related to Energy or Battery.
- On some Lyriqs, there’s a section labeled Battery Capacity. This displays the capacity of the high‑voltage battery compared to when it was new, with a “battery capacity at vehicle delivery” value and a current value.
- You may also find efficiency and energy‑usage cards that show consumption over your last trip or last 30 miles, helpful for separating driving style from true battery health.
Naming can vary
Depending on your model year and software, Cadillac may label this app Vehicle Status or Vehicle Information. Either way, the battery capacity readout is the Lyriq’s way of telling you its state of health.
How the Lyriq estimates battery state of health
The Lyriq rides on GM’s Ultium platform, and like other modern EVs it constantly monitors the pack through a **battery management system (BMS)**. That BMS is the quiet accountant in the background, tracking electrons in and out and estimating long‑term battery health.
What feeds the Lyriq’s SOH estimate?
You don’t see this math, but it’s happening every time you drive or charge.
Charge & discharge history
Temperature exposure
DC fast vs. AC charging
Crucially, the Lyriq’s SOH number is a **model**, not a lab test. Software updates can refine that model, which is why some owners see their indicated capacity or projected range change after an over‑the‑air update with no real‑world difference in how far the car drives.
Don’t overreact to a single snapshot
A one‑time drop in displayed range or capacity could be the BMS recalibrating, recent cold weather, or a string of short, inefficient trips, not sudden battery damage.
What’s normal battery degradation on a Cadillac Lyriq?
The Lyriq uses a large Ultium pack, on the order of 100 kWh usable, so its **per‑mile stress is relatively low** compared with small‑battery city EVs. Early owner data across EVs generally points to single‑digit percent loss over the first few years when the car is treated decently.
Realistic expectations for Lyriq battery health
Every pack ages differently
Climate, driving style, storage habits, and software all matter. A Lyriq that lives in a cool garage at 50–60% charge ages very differently from one parked at 100% in direct sun in Phoenix.
Habits that hurt or help your Lyriq’s state of health
Habits that quietly damage SOH over time
- Parking at 100% for days – High voltage and heat together are the battery’s enemies.
- Living on DC fast charging – Great for road trips, not as a daily diet.
- Letting it sit near empty – Repeatedly leaving the pack below ~10–15% for long periods isn’t ideal.
- Chronic heat exposure – Hot climate, no shade, no garage; the thermal management can only do so much while parked.
Habits that protect your Lyriq’s SOH
- Daily charge limits – Using the Charging app’s target level (50–80%) for everyday driving.
- Home Level 2 charging – Slower, gentler charging when you’re not in a rush.
- Garaging when possible – Reduces thermal stress in both summer and winter.
- Occasional full cycles – Now and then, letting the car run from low to high SOC helps the BMS recalibrate more accurately.
Set it and forget it
If you only drive 30–60 miles a day, set your Lyriq’s home charge target somewhere around 60–80% and plug in regularly. You’ll still have more than enough range and you’ll be kinder to the battery.

When the numbers look wrong: understanding weird SOH or range readings
Lyriq forums are already full of stories that go like this: a software update lands, the displayed range changes, someone panics, and then… nothing dramatic happens in real life. The car still does the same commute with the same buffer. That tension, between what the screen says and what the car does, is where you need to be a little analytical.
Four common reasons SOH or range readings look “off”
Not every scary number is real degradation.
Cold weather
Recent driving style
Software recalculation
Genuine fault
When to stop guessing and call for service
If your Lyriq won’t charge properly, shows repeated high‑voltage or propulsion warnings, or drops a huge chunk of indicated range overnight with no clear reason, have it inspected. Those symptoms go beyond normal SOH drift.
Buying a used Cadillac Lyriq? Battery SOH checklist
On a used Lyriq, state of health is the single most important hidden variable. The cabin tech, the light show, the chrome, those are distractions. The battery pack is the car. Here’s how to interrogate it politely before you sign anything.
Used Lyriq battery health checklist
1. Capture the in‑car battery capacity reading
Sit in the vehicle, open the Vehicle Status/Information app, and photograph the <strong>Battery Capacity</strong> screen. That’s your starting SOH reference.
2. Compare mileage to SOH
A low‑mileage Lyriq with unusually low battery capacity (for example, below the high‑80s) deserves extra questions. Heavy DC fast‑charging or extreme climates can accelerate wear.
3. Cross‑check with a real‑world drive
On a test drive, note miles driven and battery % consumed. If the car burns, say, 20% to go 25 miles on mixed roads in mild weather, that’s a clue the practical range is below spec, even if the SOH number looks fine.
4. Ask about charging habits
How did the previous owner charge, mostly home Level 2, or public DC fast chargers? Did they leave it at 100% often? Their habits are part of the SOH story.
5. Check for past service visits and campaigns
Ask for service records, especially if there were battery‑related warnings, charging failures, or software reprogramming. Confirm any battery‑related campaigns or fixes have been applied.
6. Verify warranty status and coverage
Look up the in‑service date and mileage to see how much battery warranty remains. On a borderline SOH car, remaining coverage can be the difference between “interesting deal” and “run away.”
How Recharged changes the equation
Every Lyriq listed on Recharged comes with a Recharged Score Report that includes verified battery health, fair‑market pricing, and expert EV inspection. Instead of guessing from a single in‑car screen, you see exactly how that vehicle’s pack is performing, and how it compares to similar Lyriqs on the market.
Warranty, software fixes, and what protects you
EVs live and die by software. The Lyriq is no exception. Early owners have seen everything from 12‑volt battery drain after over‑the‑air updates to high‑voltage system warnings that were ultimately fixed with reprogramming. That’s the messy adolescence of a brand‑new EV platform. The good news: you’re not defenseless.
Key protections for a Cadillac Lyriq’s battery & electronics
Exact terms can vary by model year and market; always confirm for the specific VIN you’re considering.
| Protection | What it typically covers | Why it matters when SOH drops |
|---|---|---|
| High‑voltage battery warranty | Defects in materials or workmanship, often with a minimum capacity guarantee over a set time/mileage. | If your SOH falls below the warranty threshold while you’re still covered, you may qualify for repair or pack replacement. |
| Power electronics & drive unit | Inverter, onboard charger, and related components. | Some “battery” problems are actually power‑electronics issues that affect charging or range; warranty can address those too. |
| Software campaigns & updates | Targeted fixes for known issues like charging behavior or dashboard errors. | A software campaign can change how SOH is calculated or displayed, resolving confusing readings without hardware changes. |
| Customer satisfaction programs | Specific, often time‑limited fixes (e.g., 12‑volt battery drain issues). | These programs quietly solve early‑production problems that could otherwise look like poor battery health. |
Use this table as a conversation starter with a seller or service advisor, not as a substitute for reading the warranty booklet.
Always read the fine print
Don’t assume all Lyriqs share identical warranty terms. Model‑year changes, in‑service dates, and regional differences all matter. Before you buy, ask the seller, or a Recharged specialist, to verify the exact battery and powertrain coverage on that VIN.
