Buying a used electric vehicle offers great savings—but the battery’s condition is often its most uncertain factor. A Battery State-of-Health (SOH) certificate provides the clarity both buyers and sellers need. By plugging into the car’s Battery Management System (BMS), a professional diagnostic captures real performance data. That data is then analyzed and turned into a digital certificate, complete with a unique QR code for online listings. With this certificate, sellers can prove battery quality and buyers get assurance that they’re making a solid investment. At BatteryChecked.ie, we provide independent EV battery diagnostics and issue SOH certificates within 24 hours, helping make the used EV market safer and more transparent.
