What to verify before choosing
The stated battery range is 100–2000 CCA for supported flooded, AGM flat-plate, AGM spiral, GEL and EFB batteries. This is a supplier specification, not an independent accuracy test. Supplied documents disagree on weight and dimensions; confirm the actual package and revision before purchase. Follow the battery and tool instructions for connection and settings.
Designed for supported OBD-II / EOBD vehicles. Available data and functions depend on the vehicle, model year and diagnostic protocol. Engine OBD support does not imply ABS, SRS, transmission or service-function coverage.
