Understanding the Technology

The KW720 uses conductance-based battery testing, which measures internal resistance to accurately assess battery health without requiring a full discharge cycle. Unlike older load testers, this method delivers reliable results even on partially charged batteries — critical for high-volume workshops across diesel Indian fleets. The integrated thermal print engine uses the same technology found in point-of-sale receipt printers, ensuring low-cost, readily available paper refills across India. This makes the KW720 a true battery system tester beyond a basic car battery capacity tester.
