CARA Approved
Generational is a CARA Approved Battery Health Check provider. CARA provides the industry accreditation for electric vehicle battery diagnostics, meaning retailers, remarketers and customers can trust the accuracy and reliability of our results.
Mileage doesn't tell the whole battery story
Age and mileage alone cannot tell you how an EV battery has been used or how it is performing today. Battery condition is influenced by charging habits, driving behaviour, age and factory variation. Two vehicles with the same mileage can have very different batteries.
Generational gives your team vehicle-specific evidence before buying, pricing and selling.
Usage and charging
How a vehicle has been used and charged can affect battery condition, long-term performance and resale confidence.
Driving behaviour
Vehicle driving style and operating conditions can influence degradation, efficiency and the battery’s long-term value.
Vehicle variation
Battery condition does not follow a fixed pattern. Vehicles of the same age and mileage can perform very differently.
Turn battery insight into better business
Sell stock faster
Give customers clear evidence of battery condition, range and warranty to remove uncertainty from the buying decision.
De-risk part exchanges
Check battery condition before committing and uncover potential issues that age and mileage alone may not reveal.

Boost for aftersales

Go beyond a headline State of Health figure
A single State of Health percentage does not always tell the full story of an EV battery.
Two vehicles can return a similar overall score while the condition of the individual cells within each battery pack is very different.
That is why Generational combines State-of-Health with cell-level diagnostic checks. By highlighting inconsistencies between cells, retailers gain a clearer view of battery condition and can identify potential issues that a headline percentage alone may miss. It supports better-informed decisions when buying, appraising, pricing and selling used EVs, while giving customers stronger evidence about the vehicle they are considering.
