UK battery-testing provider Generational has partnered with diagnostics tool supplier Maverick Diagnostics to bring its EV battery health testing technology to roughly 6,000 workshops across the UK. Generational, which provides EV battery health checks and State of Health certification for the used EV market, will supply testing kits, fulfill workshop orders, and operate the software platform behind the checks and customer-facing reports. Maverick Diagnostics, which supplies OEM-approved diagnostic tools and technical support to independent workshops, will market the technology and provide educational materials to its network. The companies are positioning the service as a route for motorists to access battery condition data through repair shops they already use for routine service.
Highlights
- Generational’s EV battery health testing technology becomes available at roughly 6,000 UK workshops through the Maverick Diagnostics network.
- The companies are encouraging EV owners to add battery health checks to annual maintenance, alongside a service appointment or an MOT test — the UK’s annual vehicle inspection.
- Generational’s test connects a device to a vehicle’s OBD port and produces a State of Health report, including cell-level condition data, within minutes.
- According to Generational’s Battery Performance Index, based on more than 8,000 UK battery assessments, average battery State of Health stands at 95.15%, though variance between vehicles increases with age.
How the Partnership Divides the Work
Under the agreement, Generational retains distribution and product responsibilities — shipping testing kits, handling workshop orders, and running the software platform that generates State of Health reports and certificates. Maverick Diagnostics takes on marketing and workshop education, using its existing relationships with roughly 6,000 UK garages to introduce the tool. The deal follows Generational’s earlier push into dealership channels, including a nationwide rollout across Motorpoint’s UK network, extending the same underlying technology into independent repair shops for the first time.
Andy Brooke, CEO of Maverick Diagnostics, said workshops are being asked to service increasingly sophisticated vehicles, and framed EV battery condition as one of the biggest questions their customers raise. “Garages need tools that are accurate, easy to use and commercially practical, and motorists need information they can understand and trust,” he said. “By bringing Generational’s battery testing software into our distribution and support model, we are giving workshops a credible way to answer those questions.”
Oliver Phillpott, CEO of Generational, said the partnership puts the company’s technology directly into workshops motorists already rely on: “Maverick Diagnostics is one of the most trusted names amongst UK workshops, and this partnership enables us to put Generational’s technology into the hands of the repairers motorists already rely on. Together, we can make battery testing accessible at scale, giving consumers clear, data-backed answers in minutes.”
Why Battery Condition Is Becoming a Maintenance Checkpoint
The companies point to a fast-growing used-EV market in which battery condition — rather than mileage alone — increasingly determines resale value. They are encouraging owners to include a battery check as part of annual maintenance: during a service, an MOT appointment, a pre-purchase inspection, or before selling a vehicle.
Phillpott argued the check should become a routine part of ownership rather than a discovery moment. “Battery health should not be something consumers only discover when they are buying a car, selling a car or when something goes wrong,” he said. “It should become a familiar part of EV ownership, in the same way motorists understand the importance of service history, mileage verification or an MOT.”
How the Testing Works
Generational’s process is built for workshop staff without specialist EV training. A compact device plugs into the vehicle’s OBD port, and the software assesses battery condition data to produce a customer-facing report. That report includes a cell-level voltage breakdown Generational added to its diagnostic platform earlier this year, showing how individual cells compare against the pack’s original capacity rather than just an overall percentage. For workshops, the company frames this as a new EV service line as more electric vehicles move into their second and third ownership cycles.
Battery Performance Index Findings
Generational’s data draws on its Battery Performance Index, built from more than 8,000 battery health assessments conducted across the UK in 2025. The assessments span:
- Vehicle age: 2013–2025 model years (0–12 years old)
- Mileage: 0 to more than 160,000 miles
- Manufacturer coverage: 36 manufacturers
- Vehicle types: passenger BEVs, PHEVs and light commercial vehicles
According to the Index, average battery State of Health across the sample stands at 95.15%, with many older and higher-mileage vehicles performing strongly. The company reports that variance between individual vehicles widens with age, which it says reinforces the case for testing on a case-by-case basis rather than relying on age or mileage as a proxy. Generational says the Index will be published annually as a recurring UK benchmark for battery condition.
Generational has previously received funding through the Advanced Propulsion Centre UK, which the companies describe as recognition among a small cohort of British automotive technology start-ups selected for their contribution to net-zero innovation.
