Seems well made. I've used it on 6v batteries and 12 volt auto batteries and no issue. In the description it says it has an option for load testing but scrolling through it all and it does not show it. I'm not sure if it's built in when testing and that's how it shows the results. The quick battery test feature is a nice if a battery doesn't have a tag or you can't read it. I have no issues with it. Tests batteries how it's supposed to and does a bit more on readings. Good for home use and good to have in the tool box for a quick check option. ## Frequently Bought Together - VDIAGTOOL BT300 Car Battery Tester 6V 12V, 5-3000 CCA Load Tester Starter Alternator Tester Automotive Charging Cranking System Tester for Motorcycle Car Truck SUV ATV Boat - VDIAGTOOL V200 Pro Automotive Power Circuit Probe Tester Breaker Finder Tool, 12/24V Electrical Open Short Circuit Finder, Wire Tracer, AC DC Voltage Trailer Relay Fuse Test - VDIAGTOOL Bidirectional Scan Tool VD70, OBD2 Scanner Diagnostic Tool with ECU Coding, 36+ Resets, PMI, FCA AutoAuth, All System, CAN FD & DoIP, V.A.G.
