TOPDON Car Battery Tester 12V BT50, Automotive 100-2000 CCA Battery Load Tester, Cranking and Charging System, Auto Test Scan Tool, Digital Battery Alternator Analyzer (Upgraded Version of AB101)

This is a terrific unit. Easy to use. Saves test results. Compact and extremely well built. Although the manual refers to a BT20 app, it is not currently available with that name. The developer has provided a work around. Scan the bar code in the manual and it takes you to a YouTube video. You’ll need to download the TestFlight app and the Battery Lab app. Test Flight will provide a code to use to open Battery Lab which is essentially the BT20 so called app. It works very well. I have used for accurate readings on our boat batteries and our two autos with no issues whatsoever. Great tool that is a must for any tool box. As always great to have a good idea of your battery’s state of charge before going to the dealer for service!!
