Review: Properly functioning - 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.
Review: Worked Perfectly - High Quality - 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.

### ⭐⭐⭐⭐ So far so good
*by F***Z on August 24, 2025*

I've tested 6 marine batteries since purchase, tester alerted to 2 OK but aging batteries and 1 that was near life end. Others tested good. Test details will allow you to "monitor" battery life status if you keep the reports/data. Documentation shows how to enter Tech name and Store name info but does not appear to save it and enter key only adds additional characters. Battery # is similar as it does not appear to save name for print out which is important when printing reports for multiple batteries. Contacted seller to see if there is a key sequence to save the info vs. entering it each time.
