The built-in car battery tester walks you through a 3-step diagnostic sequence: Battery Test (SOH, CCA, SOC, internal resistance) → Cranking Test (cranking voltage & time) → Charging Test (alternator output & ripple detection). This battery and alternator tester can instantly identify whether the problem is your battery, starter, or alternator – no more guesswork or unnecessary replacements
