General Introduction
MaxiBAS BT608
Touchscreen Battery & Electrical System Analyzer
The MaxiBAS BT608 battery and electrical system analyzer is a full-featured
battery and starting/charging systems diagnostics tool. The BT608 uses a
technology called Adaptive Conductance to more accurately determine the
health of battery than traditional battery testers. The BT608 can quickly display
both voltage and healthstatus of the existing battery, register a new battery, and
perform advanced battery and electrical diagnostics. The BT608 is also an
advanced diagnostics tool that can identify faults in all systems and display live
data relating to those faults. The easy-to-use Android-based touchscreen tool
provides Wi-Fi software updates as well as Wi-Fi printing and sharing of the
shop-customized reports which can be printed out with the built-in thermal
printer.
There are two main components to the MaxiBAS BT608:
MaxiBAS BT608 Tester — the touchscreen battery & electrical system
tester
MaxiVCI V200 — Vehicle Communication Interface
