Who needs this test

Three questions.
One answer.

An Aviloo certified battery check solves a specific problem for three specific people. If you recognise yourself here, you need this.

01 — BUYER

Before you hand over money

"The dashboard says 88%. The seller says it is fine. But the dashboard is an estimate from the car's own computer — and you are about to spend £12,000."

→ Pre-purchase certificate

02 — SELLER

Stop negotiating against doubt

"Your battery is fine, but every buyer wants £500 off 'because of the battery'. Hand them an Aviloo certificate and that conversation ends."

→ Seller's certificate

03 — OWNER

Know what you've got

"Your range isn't what it used to be. Is it the weather, your driving, or has the battery actually degraded? Stop guessing."

→ Owner's health check

Common questions

Real questions.
Straight answers.

Completely safe. The Aviloo test reads data from your battery management system passively. It does not charge, discharge, stress, or modify the battery in any way. Zero risk to the battery or your manufacturer warranty. The process is silent and non-invasive, taking ~20 minutes on site.

A main dealer's check is a self-assessment from the car's own system. An Aviloo certificate through PAD is third-party verified using independent equipment that doesn't rely on the car's own estimate. That independence is exactly what gives the certificate credibility with buyers and insurers.

Research shows certified EVs sell for £450–£900 more on average than equivalent uncertified vehicles — and sell faster, because buyers stop negotiating against an unknown. For most sellers the £79 test recovers itself many times over.

You get the exact number either way — PAD doesn't soften results. If SOH is low, you have that information before you buy (walk away or negotiate hard), or you know your real range as an owner. If it's healthy, you have proof. Either result is better than the uncertainty you have now.

Yes — see the PHEV battery check. Coverage includes 73 plug-in hybrid variants. Standard hybrids (Toyota Prius, etc.) are not usually tested this way — they use different battery architectures. WhatsApp us with your specific vehicle if unsure.

Aviloo's coverage is expanding constantly. Check your vehicle first, and if it's not listed, message us on WhatsApp with your reg. We can usually confirm availability within a few minutes — most common UK EVs are supported.
