UT673A User Manual (PDF)FAQs
Q1: Do I need to charge this battery tester before using it?
A: No, you do not need to charge it. Specifically, this device does not contain internal batteries. Instead, it is powered directly by the vehicle battery you are testing. Therefore, it is always ready for immediate diagnostic use.
Q2: Can I test a 24V truck system with this device?
A: Yes, you absolutely can. First, it tests 12V regular lead-acid cranking batteries perfectly. Furthermore, it easily performs comprehensive cranking and charging system tests on heavy 24V setups. Consequently, it is highly ideal for large trucks and boats.
Q3: What exactly does the cranking and charging test do?
A: Basically, the cranking test analyzes your starting motor. Specifically, it checks if the motor works properly under load. Meanwhile, the charging test evaluates your alternator’s output. Thus, it strictly prevents battery damage caused by dangerous overcharging.
Q4: Will it break if I accidentally connect the clips backwards?
A: Fortunately, it will not break at all. We engineered this tool with strict reverse polarity protection. Consequently, crossing the positive and negative cables will not damage the internal circuitry. Ultimately, it ensures complete safety during fast inspections.
