Every TOPDON car battery tester uses conductance testing to check battery health in seconds, with no heat, sparks or battery drain. All five test Flooded, AGM, Gel, EFB and VRLA batteries from 100 to 2000 CCA, and double as a cranking (starter) and charging (alternator) tester. The differences are 24V truck support, a built-in printer, screen size and professional workshop features.

Battery voltage tested is the battery the tester can assess directly. Cranking & charging system voltage is the vehicle system it can check. Only the BT600 Plus tests 24V batteries directly; the BT200, BT300P and BT600 test 12V batteries and check the cranking and charging systems of 24V vehicles.
