Works as it should
Our local parts store wanted us to use this tester to justify any warranty claims with their batteries. I switched shops and wanted my own tester

The BT300p, arrived well packaged,& it performs as proscribed I like its performance, including the speed at which it performs and prints out a report. The battery tests are accurate and through. . I’m happy I bought it !
