This battery, starting, a d charging system tester is excellent. I purchased it to .ake my life easier when doing an inspection that requires this information. It comes in a nice hard carrying case. I open the case, attach the sufficiently sized alligator clips to the tester body, then attach the clips the the battery being tested. I can test only a battery outsideof a vehicle if I want to. Or I can test the battery in a vehicle, then proceed to start the vehicle in order to test the starter cranking voltage, then once running I can finish by testing the alternator and charging system. Once the tests are complete and the program has run, I can print out a receipt that states whether the battery and subsequent tests have passed or failed. It is all very intuitive and easy to use. Similar to an alignment machine it really walks you through the steps. So, this battery, starting, and charging system tester, is a winner in my book.

Like the unit, only issue is setting the date and time for the printouts. In the quick tour guide it says to hold the left, down and menu buttons simultaneously. This has no effect. Messaged Foxwell customer support 5 days ago, no word back as of yet.

Worked perfectly. Was easy to conduct the test based on the prompts it gave, and being able to just print the results in a nice. So far very happy.

Print quality is poor. Won't print off internal battery (even when replaced). Reports out of vehicle 12v battery test as a 24v system. Returned and bought TopDon brand instead.
