Understanding the Technology

The BT780 uses conductance-based battery analysis — a method that measures internal resistance to determine true battery health without full discharge cycles. Unlike voltage-only testers, conductance testing accurately detects sulphation and plate degradation common in Indian conditions where extreme heat accelerates battery wear. This makes it the preferred car battery tester for workshops handling def in diesel vehicles, EFB start-stop systems, and ageing flooded batteries alike. The cranking and charging system tests further diagnose alternator output and starter draw in one workflow.
