Bluetooth Voltage Monitoring for Vehicle Batteries
The Voltage Test area is the everyday starting point for a vehicle battery check. With a compatible BM2 monitor nearby, users can bring live voltage readings into the Android app through Bluetooth and use the central graph to follow changes rather than relying on a single number. The interface keeps the battery-focused workflow separate from the other test tabs, so a quick status check is easy to find.
Historical readings add context when a battery behaves differently across days or trips. Users can return to the voltage view to compare recent behavior, spot a gradual drop, and decide whether a closer inspection or recharge is worthwhile. It is a practical dashboard for owners who want a clearer record of battery condition.
Cranking Tests for Starting-System Checks
Cranking Test focuses on the voltage behavior that appears while the vehicle starts. The dedicated tab presents a cranking-voltage card, a standard-range guide, and a time-based graph, giving users a focused place to review the starting-system result instead of mixing it with ordinary battery readings. The large layout keeps the key value and its reference range visible at a glance.
A connected monitor can supply the reading while the driver or technician carries out a start attempt. Repeating the check over time helps distinguish a one-off reading from a pattern, which is useful when investigating slow starts, a tired battery, or a starter-system concern before booking service.
Charging Tests and Idle-Condition Guidance
Charging Test provides a separate workflow for checking the vehicle’s charging system at idle and at higher engine speed. Its preparation screen gives practical steps before testing, including starting the engine, switching off unnecessary loads, and turning on the headlights. That guidance helps users create a more consistent check instead of recording a result under changing conditions.
The app keeps charging work distinct from the cranking view and leaves room for the measured result and graph once a compatible monitor is connected. Drivers can use the idle and high-speed routines to review alternator behavior, while technicians can repeat the same sequence when comparing a vehicle before and after maintenance.
Trip Records and Wear OS Status Views
Trip gives Battery Monitor a place for journey-related records alongside its electrical checks. The tab is separate from Voltage, Cranking, and Charging, so users can keep a trip view ready when they want to relate battery behavior to a drive or revisit travel data later. If no record is available, the app presents a clear empty state rather than inventing a reading.
The wider BM2 ecosystem also includes a Wear OS view for device information and battery, startup, and charging test data. A compatible watch can therefore act as a quick reference while the phone remains the main place for Bluetooth monitoring and detailed review.
