You don't know what
that battery's worth.
We do.
Price it right before you buy. Mark it accurately before you lend. Know the exposure before 2028.
One ladder. Three audiences.
An independent dealer needs a clearing price in under a minute. A risk manager preparing a credit-committee submission needs a defensible report. Volt Delta serves both — the same engine, three levels of depth.
Bid with confidence on a forecourt.
A clean clearing price the moment a car shows up. Level 1 takes a minute. Use it before you make an offer.
Mark a book to today's market.
Full diagnostic with portfolio context, warranty-cliff exposure and listing dispersion. Defensible to a credit committee.
The confidence ladder.
Most pricing platforms force you into the same form regardless of what you're doing. Volt Delta lets you stop when you have enough confidence — and keep going when you don't.

Run at Level 3Independent EV market analysis.
Notes from the Volt Delta research desk on battery condition, residual values, listing dispersion and the 2028 warranty cliff.
The 2028 warranty cliff: mapping the first wave of unprotected EV exposure
Roughly 300,000 mass-market EVs sold between 2020 and 2023 will leave manufacturer battery warranty between Q4 2027 and the end of 2028. Most lenders haven't modelled what that means for residuals.
Why two identical ID.3s can be worth £1,800 apart — and how dealers spot it
Same year, same trim, same mileage, same colour. One walks off the forecourt at £18,400; the other sits for two months and clears at £16,600. The gap is almost always observable in five minutes.
Battery State of Health, observed condition, and why the slider beats the spec sheet
OBD2 State of Health is a number. Observed condition is a judgement. Used correctly, the judgement is the more accurate residual predictor — and we can show you why.
Independent of OEMs, auction houses and listing platforms.
Volt Delta has no commercial interest in the transaction outcome. Pricing intelligence you can put in front of a counterparty, a client, or a credit committee.
