Mobile EV Battery Health Check in Watford

The Mobile EV Battery Health Check costs £99 for a successful test within Dual Action Roadside's standard service area.

The £99 includes mobile attendance within the standard area, compatibility checked before confirmation, the AVILOO FLASH traction-battery test where the vehicle is supported, AVILOO analysis, a digital AVILOO Battery Certificate after a successful test, and Ray's plain-English explanation.

Dual Action Roadside is based in Watford, Hertfordshire and covers its existing 10-mile service area around Watford. Your appointment postcode is checked before Ray confirms attendance.

The AVILOO FLASH stationary test normally takes approximately three minutes, according to supplier research. The appointment may take longer because Ray needs to attend, check access, connect equipment and explain the result.

No. Submitting the form requests an appointment. It is not confirmed until Ray has checked vehicle compatibility, postcode and availability.

The service is for supported fully electric vehicles. Ray must check compatibility before confirming because not every EV, model or variant is automatically supported.

Supported plug-in hybrid vehicles may be eligible. Compatibility must be checked before confirmation, so please provide the registration, make, model and year.

Ray will normally need the vehicle registration, make, model, year and whether it is fully electric or plug-in hybrid.

State of Health describes the current condition of the high-voltage traction battery compared with its expected usable condition. It is different from State of Charge, which is simply how full the battery is.

The certificate may show State of Health, usable battery information, cell-level findings, a heatmap, comparison data, range information and digital verification where provided. The exact fields can vary by vehicle and test result.

The digital Battery Certificate is issued by AVILOO after a successful test. Dual Action Roadside does not issue, edit or underwrite the certificate.

No. The check is a snapshot of traction-battery condition at the time of testing. It does not predict remaining lifespan or guarantee future performance.

No. It is a traction-battery health check. It is not a complete EV inspection, mechanical inspection, safety inspection or substitute for manufacturer diagnostics.

No. The service does not include dismantling, physical battery inspection or high-voltage safety inspection.

No. This £99 service checks the high-voltage traction battery where the vehicle is supported. Ordinary 12-volt battery jump starts and replacements are separate Dual Action Roadside services.

Yes. A private seller can request a test to provide clearer information to prospective buyers, subject to compatibility, postcode, access and appointment availability.

Range can change because of temperature, weather, driving style, speed, tyre pressure, heating use, software and battery condition. The test can report battery condition at that time, but it does not diagnose every possible range issue.

Qualifying tests may include a separate AVILOO Battery Warranty, subject to vehicle eligibility and AVILOO's terms and conditions. It is not guaranteed with every test and is not supplied or underwritten by Dual Action Roadside.

Payment is made on the day after the test has been completed successfully. No payment details are collected in the online appointment request.

If the test cannot be completed because the vehicle is not supported or the available equipment is unsuitable, the £99 test fee will not be charged.
