UNI-T Autobatterietester UT673A UT675A 12V 24V DC Lasttester Kapazitätsmesser Batterieprüfer

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.
