Generational vs Altelium: Battery Test vs Battery Warranty

Generational vs Altelium

A comparison of two products often discussed together but solving different problems.

Generational is a battery health testing service that reads the State of Health value already calculated by the vehicle's Battery Management System¹.

Altelium is a specialty battery insurance MGA — a Lloyd's Lab Cohort 9 alumnus², distributing extended battery warranties through the GardX EVerity programme³.

A health test answers "what is the condition of this battery now?" A warranty answers "what happens if this battery fails later?" These are not substitutes for each other.

Different problems, different products

Generational is testing technology. The dealer learns what the vehicle's Battery Management System currently reports as SoH, plus range estimates, warranty status and cell-balance flags⁶.

Altelium is insurance. The dealer (or buyer) gets financial cover if the battery fails or degrades faster than expected within the warranty term. The cover is underwritten by 'A'-rated insurers through the Lloyd's of London market⁵. Coverage extends "beyond the age or mileage limits of manufacturers' warranties"⁵.

These are not substitutes. Under the Consumer Rights Act 2015, the question is about condition at point of sale. A warranty does not address that question — it transfers future risk. A test report addresses condition at sale, but the strength of the report depends on the certification behind the methodology.

Different kinds of credential

• Generational describes its methodology as "in line with the Car Remarketing Association Europe (CARA) guidelines"¹. Their institutional partners include APC, UKRI, the Department of Business & Trade, the Automotive Council UK, and IMDA⁴. None of these bodies perform engineering certification of testing methodology.
• Altelium carries Lloyd's of London market underwriting on the warranty product⁵. Lloyd's underwriting is a financial-sector credential — it stands behind the warranty pay-out, not the diagnostic methodology.

Neither Generational nor Altelium appears on CARA Europe's approved providers list⁹. Neither holds TÜV certification of a diagnostic methodology.

What neither system provides

For dealers who want an independently calculated SoH with a cell-level severity heatmap, backed by TÜV certification of the testing methodology, with the AVILOO Flash Test also listed on CARA Europe's approved providers list, those features are available from AVILOO — the system Battery Health Check uses⁹.

A dealer can credibly use AVILOO for the diagnostic-evidence side and Altelium-style warranty cover as a separate revenue product. They aren't competing with each other.
