The UNI-T UT673A car battery tester is an advanced device that enables a quick and accurate analysis of the condition of batteries with capacities from 3Ah to 250Ah. Certified to CE, UKCA and FCC standards, the UT673A enables the testing of 12V lead-acid starter batteries and the verification of 12V/24V charging and starting systems. The tester displays the most important parameters such as capacity, voltage, resistance and battery life status. With a four-point Kelvin test and support for up to 10 different battery standards, the UT673A provides highly accurate results without disassembling the battery. It also displays the test result in the form of an easy-to-read LED indicator light.
The UNI-T UT673A enables a comprehensive examination of both the state of charge of the battery and the operation of the vehicle's starting and charging system. The device allows you to select the operating language (Chinese or English), so the device can be easily used in different work environments. The four-point Kelvin measurement function eliminates the effect of wire resistance, thus ensuring even greater accuracy. Support for 10 types of battery standards enables tests adapted to different technologies and manufacturers, making the UT673A an extremely versatile tool in the automotive workshop or service center.
The UT673A tester is characterized by its robust construction and compact form, making it ideal for both workshop and field work. The test results are clearly displayed on the display, and the additional indicator with colored LEDs allows you to immediately assess the state of the battery. Not having to disassemble the battery during testing significantly speeds up the work and minimizes the risk of damage. The UNI-T UT673A is a reliable support for all those who rely on professionalism and accuracy during battery diagnostics.
