Understanding the Technology

The BK400 uses conductance-based battery testing, sending a low-frequency signal through the battery to measure internal resistance without discharging it — far more accurate than traditional battery load testers. This method detects sulphation and plate degradation early, which is critical given India's extreme heat accelerating battery ageing. Unlike analogue load testers, the digital battery tester algorithm calculates true cold cranking amps (CCA) remaining, giving a precise health snapshot in seconds.
