Product Features

Complete 4-Parameter Battery Diagnosis

This car battery tester reads four critical battery parameters simultaneously: SOH (State of Health), SOC (State of Charge), internal resistance (R), and voltage (VOL). Results are displayed as Good, Normal, or Poor — giving you an instant, actionable verdict on whether your battery needs replacing.

Wide Compatibility — Multiple Battery Types

Compatible with Normal, EFB, AGM Flat, AGM Spiral, and GEL battery types across 6V, 12V, and 24V systems. Whether you're testing a motorcycle battery, a truck battery, or a lawn mower, this tester handles it all with the same accuracy.

Built-In Safety Protections

Polarity reverse protection prevents damage if the clips are connected incorrectly. Over-voltage input protection safeguards the tester from electrical spikes. A poor contact prompt alerts you if the clips aren't making a solid connection — so every reading is reliable.
