AVILOO vs Altelium: Battery Test Comparison
Compare AVILOO and Altelium EV battery solutions. TUV-certified health testing vs warranty-backed GardX EVerity programme for UK car dealers.
AVILOO vs Altelium — How Do They Compare?
AVILOO and Altelium approach the EV battery confidence challenge from different angles. AVILOO provides TUV-certified battery health testing and certification. Altelium combines health assessment with an insurance-backed battery warranty through the GardX EVerity programme, underwritten by Lloyd's of London.
These are complementary rather than purely competing approaches, but dealers typically choose one primary platform. Here is how they compare.
Side-by-Side Comparison

| Accuracy | +/-3% | Not publicly stated |
| Test time | 3 minutes (FLASH test) | Varies by programme |
| Vehicle coverage | 95%+ of EVs and PHEVs | Coverage tied to warranty eligibility |
| Cell-level analysis | Yes — individual cell heatmap | Not publicly detailed |
| Price point | ~£35 per test | Warranty pricing varies (1-3 year options) |
| Key partnerships | BCA, Cox Automotive, ADAC, Mercedes-Benz, Hyundai | GardX (EVerity programme) |
| Output type | TUV-certified interpreted certificate (SoH %, cell severity ratings) | Warranty eligibility assessment |
| Unique advantage | World's first dual TÜV-certified test | Battery warranty as an add-on product |
What Altelium Does Well
Altelium's unique position in the market is the battery warranty. No other provider in this comparison offers an insurance-backed warranty product alongside their health assessment. The GardX EVerity programme packages this for the dealer channel effectively.
The Lloyd's of London underwriting is significant — it provides genuine financial backing behind warranty claims, not just a provider's own balance sheet. Warranty options of 1 to 3 years give dealers flexibility to match the warranty to vehicle value and buyer expectations.
For dealers, the ability to sell a battery warranty alongside the vehicle is a tangible revenue opportunity and a powerful objection-handler for cautious EV buyers. "This vehicle comes with a battery warranty" is a compelling sales message.
Where AVILOO Leads
Independent Certification vs Warranty
A warranty and a health certificate serve different purposes. A warranty is a promise to pay if something goes wrong. A health certificate is evidence of condition at point of sale. Under the Consumer Rights Act 2015, dealers need to demonstrate that the vehicle was of satisfactory quality when sold. A TUV-certified health certificate directly addresses this requirement. A warranty does not prove condition — it transfers risk.
Both are valuable, but they are not substitutes for each other.
TUV Certification
AVILOO's dual TUV certification (TUV Nord and TUV Sud) means the testing methodology itself has been independently audited and certified. This is the world's first dual TÜV certification in battery health testing. In a dispute or legal proceeding, TUV-certified evidence carries recognised authority.
Cell-Level Analysis
AVILOO's certificate includes a cell-level heatmap showing the condition of every individual cell with severity indicators. This diagnostic depth means you can identify specific cell degradation, not just overall pack health. For informed buyers and in dispute scenarios, cell-level data provides the granular evidence that pack-level assessments cannot.
Interpreted Results vs Raw Data
Altelium's assessment determines warranty eligibility rather than providing an independent diagnosis of battery condition. The dealer receives a warranty — not an interpreted health certificate that documents what the battery's condition was at point of sale. If a buyer or their solicitor asks for evidence of condition at the time of purchase, a warranty does not answer that question.
AVILOO's certificate delivers an interpreted State of Health, calculated by AVILOO's algorithms and independently validated by TUV. It tells you — and the buyer — exactly what the battery's condition is, with cell-level severity ratings, backed by a certified interpretation process.
Speed and Simplicity
The AVILOO FLASH test takes 3 minutes on a stationary vehicle. There is no warranty application process, no underwriting assessment, no waiting period. Plug in, test, certificate issued. For dealers processing multiple vehicles daily, this operational simplicity is significant.
Cost Predictability
At approximately £35 per test, AVILOO's pricing is straightforward and predictable. Warranty programmes involve variable pricing based on vehicle age, value, mileage, and warranty term length. For budgeting and ROI calculations at scale, the simplicity of a fixed per-test cost is an advantage.
Global Track Record
AVILOO has completed 550,000+ tests across 30+ countries with 750+ clients. Named enterprise partners include BCA, Cox Automotive, ADAC, Hyundai, Mercedes-Benz, and Emil Frey. This track record demonstrates proven reliability across a vast range of vehicles and conditions.
Could You Use Both?
It is worth considering that AVILOO testing and Altelium warranty are not mutually exclusive. A dealer could use AVILOO for point-of-sale health certification (legal protection and buyer confidence) and offer an Altelium warranty as an additional revenue product. The health test proves current condition; the warranty covers future risk.
However, if choosing one primary platform, AVILOO through Battery Health Check provides the certified evidence of condition that the Consumer Rights Act demands, at a price point and speed that works at scale.
