Service Overview
Comprehensive EV Battery Health Certification Guide
The high-voltage battery is the most significant component of an electric vehicle, often accounting for a large portion of its total value. Unlike a traditional fuel tank, a battery’s capacity can degrade over time based on charging habits, climate, and usage. An EV Battery Health Certification provides a transparent, data-driven report on the current state of your battery’s health (SOH). At Owl-Let, we provide the technical diagnostic precision needed to confirm your battery’s performance, ensuring peace of mind for both current owners and future buyers.

View All Service LocationsFrequently Asked Questions
What is a "good" score in an EV Battery Health Certification?
Most modern EVs are designed to retain 70% to 80% of their capacity over 100,000 miles. A score above 90% is typically considered excellent for a used vehicle. Owl-Let provides a detailed breakdown of what your specific score means for your remaining driving range.
Can an EV Battery Health Certification detect a failing cell?
Yes. Our diagnostic tools look at the voltage variance between individual cells. If one cell is significantly weaker than the others, it can drag down the performance of the entire pack. Catching this early during a EV Battery Health Certification might allow for a warranty claim.
Does fast charging affect my battery health score?
Frequent use of DC fast chargers can increase internal battery temperature, which may slightly accelerate degradation. An EV Battery Health Certification will show the ratio of AC vs. DC charging cycles to give you a better understanding of how your habits are impacting the pack.
How long does the EV Battery Health Certification process take?
The data extraction and analysis usually take between 45 and 90 minutes. In some cases, we may recommend the battery be at a specific state of charge (e.g., 50% or 80%) to get the most accurate reading.
