UNI-T UT673A Car Battery Tester
The UNI-T UT673A is a car battery tester designed for fast and accurate diagnostics of 12 V lead-acid starter batteries with capacities from 3 Ah to 250 Ah. It measures key parameters including voltage, capacity, internal resistance, and battery health, while also checking 12 V and 24 V starting and charging systems. Four-point Kelvin measurement helps reduce the influence of lead resistance for more precise results. The tester supports 10 battery standards and displays results clearly on the screen, supplemented by an LED traffic-light indicator for quick assessment. Its compact design makes the UT673A suitable for both workshop and mobile diagnostics.
Four-point Kelvin measurement reduces the influence of test lead resistance and helps provide accurate results. The UT673A supports 10 different battery standards, allowing measurements to be adapted to a wide range of lead-acid batteries. Testing can be performed without removing or disassembling the battery, which simplifies routine service work.
Results are shown clearly on the display, while the integrated LED traffic-light indicator provides a quick visual indication of battery condition. The device supports Chinese and English operation and features a compact design suitable for use in automotive workshops, service centers, and mobile diagnostic work.
