Autel MaxiBAS BT508 Battery Tester

Autel MaxiBAS BT508 Battery and Electrical System Tester

The Autel MaxiBAS BT508 is a step up from the entry-level BT506 — adding a wireless Bluetooth VCI that enables battery and electrical component registration across 53 vehicle makes, plus full code reading and erasing across all available vehicle systems. Like the BT506, it pairs with a free iOS or Android app for test display, but it brings meaningfully more capability to the battery service workflow.

How It Works

The BT508 uses the same Adaptive Conductance technology as the rest of the MaxiBAS line — measuring actual cold cranking ability and reserve capacity rather than just voltage, giving technicians an accurate read on battery health and reducing misdiagnosis. The BT508 connects via the attached cable and battery clamps, pairs to your phone or tablet via Bluetooth, and the included VCI module enables battery registration functions directly through the app.

What the BT508 Adds Over BT506

• Bluetooth VCI included — enables battery and electrical component registration on 53 vehicle makes
• Read and Erase Codes on all available vehicle systems
• Illustrated battery position guide — graphic diagrams showing battery location for different vehicle makes and models
• All battery and charging system testing capabilities of the BT506

The BT508 in the MaxiBAS Lineup

Understanding where the BT508 fits helps you decide if it is the right level:

• BT506 (~$195): App-dependent, battery and charging only, no registration, no code reading
• BT508 (~$295): This tool — adds VCI, battery registration on 53 makes, all-system code read/erase
• BT608 (~$595): Standalone Android tablet, 5.5-inch touchscreen, built-in thermal printer, AutoVIN, full autoscan diagnostics, no annual update fee
• BT609 (~$795): 7-inch Android tablet, 64GB storage, all-systems diagnostics plus maintenance service functions

The BT508 is the right choice for a shop that wants battery registration capability and basic code reading without committing to a full standalone tablet tester. If you are doing higher volumes of battery service or need printed reports, the BT608 standalone tablet is worth the upgrade.
