Most battery “checks” are guessing.
Ours is proof.

The car’s own computer makes up a number. We measure every cell.

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

“Would you sell a car based on a number that could be wrong by up to 91%?”

Cell-by-cell
TÜV Certified
Independent
Temperature Compensated

Most battery checks just read the car’s computer. That on-board estimate can deviate from actual battery health by up to 91%. The AVILOO test is the world’s first dual TÜV-certified independent battery evaluation. It actually measures the battery, then gives you a certificate that carries real evidential weight.

The maths doesn't lie.

20 EVs/month × £30 (Silver tier) £600 cost
20 EVs/month × £450 minimum uplift £9,000 revenue
Return on investment 15x every month

Based on minimum reported uplift of £450 per vehicle. Industry data suggests £450–£900 per certified vehicle.

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.”

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 prices¹. Trust converts browsers into buyers and eliminates the battery question mark.

£2,700 Battery Warranty

Every qualifying test now includes the AVILOO Battery Warranty at no extra cost: 12 months of insurance-backed cover, VIN-tied and transferable to the next owner.
