Autel MaxiBAS BT609 Battery Tester

Autel MaxiBAS BT609 Battery and Electrical System Analysis Tablet

The Autel MaxiBAS BT609 is the top of Autel's dedicated battery tester line — a 7-inch Android tablet that combines comprehensive battery and electrical system testing with full all-system diagnostics, service menu functions, and AutoVIN vehicle identification. It is the tool for shops that want a single device handling battery service, code reading, basic maintenance resets, and test reporting without connecting to a separate scan tablet.

What Separates the BT609

The BT609 is the only model in the MaxiBAS lineup that includes full maintenance service functions alongside battery testing. Where the BT608 does all-system code reading, the BT609 adds a service menu — oil reset, EPB, TPMS, and other common maintenance resets. The 7-inch screen (vs. 5.5-inch on the BT608) makes the interface more comfortable for extended use, and the 5800 mAh battery provides a full day of shop use on a single charge.
