Features & Capabilities

Battery Master 12V is an intelligent detection tool designed specifically for lead acid batteries. When installed on a battery, it accurately tests the battery's Cold Cranking Amps (CCA) and overall health condition. Using temperature and CCA data sheets, it calculates the available usable life of the battery for precise monitoring.

The app seamlessly syncs with the device when your phone is nearby to automatically retrieve test results. Users can also test the battery health, cranking system, and charging system manually. In addition, all saved historical test results can be conveniently shared or printed for record-keeping and analysis. This extension ensures efficient battery diagnostics and maintenance for automotive and related applications.

Results differ from other the ones shown by other tools. I don't believe this app is accurate: the same voltage is interpreted as 100% and 80% SOC; the range of SOH is from 40 to 70%. The same goes for internal resistance from 2 to 4.5 mOhms. I would return the hardware but I keep for monitoring only the voltage.
