The Hidden Risk
Battery health is the #1 unknown in used EV purchases
The battery represents 30-50% of an EV's value, yet most buyers have no idea what they're getting.
No visibility
Most dealers don't know—and can't tell you—actual battery condition. You're buying blind.
Hidden costs
A degraded battery means less range, lower resale value, and potential replacement costs of $15,000+.
No standards
Unlike mileage or accident history, there's no industry-standard way to verify battery health. Until now.
Buying elsewhere
- Trust the odometer, hope for the best
- Rely on vague 'range estimates'

Frequently asked questions
What is a battery health report?
A battery health report is a detailed diagnostic that shows your EV's battery condition including State of Health (SoH), remaining capacity in kWh, cell voltage consistency, and estimated range. It's like a medical checkup for your car's most expensive component.
How do you generate battery health reports?
We partner with Lyteflo, a leader in EV battery diagnostics. Using OBD-II scanning and proprietary analysis, we extract real data directly from the vehicle's battery management system - not estimates or guesses.
Do all Carnex EVs have battery health reports?
We're rolling out battery health reports across our inventory. Look for the battery score badge on vehicle listings. Our goal is 100% coverage - we believe every used EV buyer deserves this transparency.
What's a good battery health score?
85-100% is excellent - the battery is performing like new. 70-84% is good - normal degradation for a used EV. Below 70% indicates significant degradation that may affect range and resale value.
Why does battery health matter?
The battery is 30-50% of an EV's value. A vehicle with 95% battery health is worth significantly more than one with 75%. Without a report, you're gambling on the most expensive component.
Can I get a battery health report for my trade-in?
Yes! When you trade in or sell your EV to Carnex, we'll run a battery health scan. A high score can increase your offer - it's another reason to maintain your EV properly.
