The Science

Most battery “checks” are the car marking its own homework.
Ours is independent proof.

The car reports its own estimate. We measure every cell independently.

Car’s own estimate

potential deviation from actual health

The car’s own onboard estimate, from its battery management system. Fine for driving, but it’s the car reporting on itself.

AVILOO Test

verified accuracy

TÜV Certified, cell-by-cell measurement against lab reference.

“Would you sell a car on a number that can differ from the battery’s true health by up to 91%?”

Cell-by-cell

TÜV Certified

Independent

Temperature Compensated

Most battery checks read the figure the car’s own battery management system reports. In AVILOO’s own analysis of 1,000 batteries, that onboard estimate differed from the measured state of health by up to 91% in extreme cases. The AVILOO test is an independent, TÜV Certified battery evaluation. It measures the battery directly, then gives you a certificate that carries real evidential weight.

The Commercial Case

What it's worth to your business.

20 EVs/month × £30 (Silver tier) £600 cost

20 EVs/month × £450 minimum uplift £9,000 revenue

Return on investment 15x every month

The standard test is £35 per vehicle, from £30 on volume tiers. Based on minimum reported uplift of £450 per vehicle. Industry data suggests £450–£900 per certified vehicle.

Compliance

The law is clear.

Consumer Rights Act 2015

Defects are presumed present at point of delivery for 6 months. You need evidence the battery was healthy. This is that evidence.

EU Battery Passport

From February 2027, new EV batteries placed on the EU market require a digital battery passport. The UK is expected to follow with equivalent requirements. Early adopters lead, not scramble.

Dispute Protection

A TÜV-certified battery certificate provides independent evidence of condition at point of sale. No certificate means no defence when a buyer comes back with a £6,000 claim.

Industry Direction

The Motor Ombudsman, NFDA, and consumer groups are all pushing for mandatory battery transparency. Early movers win.

“Don't wait for regulation to tell you what your competitors already know.”

The Certificate

Tested. Assured. Certified.

The AVILOO Battery Certificate turns battery condition into a matter of trust. Whether buying, selling, or leasing, clear facts provide assurance and increase value.

Independent & Objective

Not a manufacturer reading. Not a dealer estimate. A fully independent, TÜV-certified evaluation of real battery condition, cell by cell.

Certificate = Assurance

Every certificate is your proof: to the buyer, to the insurer, to the courts. Battery health documented, timestamped, and independently verified.

Assurance = Sales

Certified vehicles sell faster at £450–£900 higher prices^¹. Trust converts browsers into buyers and eliminates the battery question mark.
