Autel MaxiBAS BT609 Battery and Electrical System Tester

Autel MaxiBAS BT609 is a professional battery and electrical system tester that combines advanced battery health analysis, starting and charging system testing, battery registration, and vehicle diagnostics in one 7” Android tablet.

BT609 uses Autel’s Adaptive Conductance technology to evaluate the actual condition of the battery, cold-cranking capability, and remaining capacity. The system is suitable for checking battery condition both before replacement and after a new battery has been installed.

In addition to battery testing, the device can test the vehicle’s starting and charging systems, register a new battery to the vehicle, and perform supported service and diagnostic functions. The wireless VCI connection enables communication with the vehicle without requiring a continuous cable connection between the tablet and the OBD port.

BT609 is especially suitable for workshops, tyre shops, battery specialists, and other professionals who need a comprehensive solution for testing modern 12 V battery and electrical systems.
