Battery testing and grading
Know what every battery is worth, in the car or out of it.
SPEX tells you what a battery is really worth and whether it is safe, in minutes, with the battery inside or outside the car.
Why state of health is not enough
Two batteries with the same figure can have very different futures.
Most battery checks report a single state of health percentage taken from the car's own system. The Pack Health Index combines several independent measures of condition, including how quickly the battery is ageing, into one score.
SPEX rapid assessment
More than 150 parameters in under 60 seconds.
A portable tool that connects directly to the battery rather than through the vehicle's diagnostic port.
Decide before it comes out
Owners, recyclers and insurers can decide what to do with a battery before it is removed.
Assess extracted batteries
SPEX also assesses batteries already removed, which diagnostic port tools cannot do.
Every assessment begins with a safety check. A battery showing a serious safety warning fails automatically, whatever its other results.
The A to E grade
As easy to read as an energy label.
Every assessed battery receives a plain-English Allye battery health report with a grade from A to E.
Excellent, suited to demanding second-life use.
Good.
Fair, suited to lighter-duty use.
Needs further testing before any reuse.
Unsuitable for reuse and routed to recycling.
Detailed pack testing
A complete picture of the next life.
Batteries that pass the rapid assessment can undergo full charge and discharge cycling in our dedicated test facility, using the same power equipment as our deployed MAX systems. This measures real capacity, resistance, efficiency and temperature behaviour, and checks how reliable the battery's own data is.
FAQ
Questions buyers ask
How do you test an EV battery that has been removed from the car?
SPEX connects directly to the battery rather than through the vehicle's diagnostic port, so it can assess batteries that are already out of the car, reading more than 150 parameters in under 60 seconds.
Is state of health a reliable measure of a used EV battery?
On its own, no. Two batteries with the same state of health can have very different futures. The Pack Health Index combines several independent measures of condition, including how quickly the battery is ageing, into one score and an A to E grade.
