The iCarsoft BT900 is a wireless battery tester designed to work with compatible iCarsoft diagnostic scanners, including the MT PRO, turning your scanner into a complete battery and charging system test solution.
Simply connect the BT900 to the battery, pair it with your compatible iCarsoft tool via Bluetooth, and run battery, cranking and charging tests directly from the scanner screen.
Ideal for DIY users, workshops and mobile technicians who want a quick and accurate way to test battery condition, starter motor performance and alternator charging output without needing a separate standalone tester screen.
The BT900 helps you check the health of a battery and the performance of the starting and charging system. It is especially useful when diagnosing slow cranking, poor battery condition, charging faults, or intermittent starting issues.
A very useful add-on if you already own a compatible iCarsoft scanner and want broader diagnostic capability around battery and charging faults.
The iCarsoft BT900 is designed to work with compatible iCarsoft diagnostic scanners, allowing battery, cranking and charging-system tests to be viewed and controlled directly from the scanner.
Please note: compatibility may depend on the scanner model, installed software and update version. Update the scanner before use. The BT900 is an add-on accessory and is not a standalone screen-based battery tester.






Box contents may vary slightly by production batch, but the BT900 tester and user documentation are included as standard.
