UNI-T UT-673A Battery Tester

The UNI-T UT673A is a professional-grade battery tester using advanced conductivity test technology to deliver fast, reliable diagnostics for 12V/24V vehicle systems. It accurately assesses battery health, cold cranking amps (CCA), internal resistance, and detects common faults in starting and charging systems. Compatible with a wide range of battery types—including AGM, GEL, EFB, and standard lead-acid—it supports capacities from 3–250Ah and multiple standards: CCA, BCI, CA, MCA, JIS, DIN, IEC, EN, SAE, and AH.

The UT673A features over-voltage and reverse polarity protection, poor contact prompts, and displays for battery life, capacity, status, and internal resistance. Its 128×64 monochrome display ensures clear readings. No external power is required—the unit draws power directly from the battery. Compact and lightweight at just 264g, the UT673A is ideal for automotive technicians and garages looking for a reliable diagnostic tool.
