The OTC Smart Battery Tester, No. 3200, offers near-instant battery, charging and starting system test results with a technician’s iOS or Android device. The tester clips onto a battery’s terminals and provides battery voltage and cold cranking amps on-screen, and also displays a QR code. Using the OTC 3200 app and a smart device with a rear-facing camera, users can read the QR code to view a full report including battery, charging system and starting system health. The pocket-sized tester will work on 6V, 8V and 12V lead-acid and AGM batteries for all light duty applications.
