One app and one certificate, used in four ways. Pick the path that fits how you work.
Turn your phone and a supported OBD2 adapter into a battery testing tool. Your name and logo on the certificate, and a score calculated and signed by BattGrade's server from the car's own data.
Hand every shopper a battery certificate they can verify themselves, so the battery question has an answer before it holds up the sale.
Test vehicles at intake and handback and keep a signed battery certificate for each one, on the same scale for every make.
Every BattGrade certificate has a public verification page and a QR code that a listing can link to today. A listing API is planned; talk to us if you want to shape it.
