## Long description

KONNWEI BK100 Bluetooth battery tester is a compact diagnostic tool for assessing vehicle battery condition and starter system performance through a wireless connection to a smartphone app. The device measures battery voltage, internal condition and cranking capability, then transmits results to the paired app for clear readouts and simple interpretation.

Key specifications
 Connectivity: Bluetooth wireless connection to smartphone app
 Supported system voltage: typical 12 V automotive electrical systems
 Measurements: open-circuit voltage, cranking/starting test and battery health assessment
 User interface: smartphone application with result display and diagnostic indicators
 Physical: compact handheld module with insulated clamps for battery terminals
How to use
Connect the insulated clamps to the battery terminals following polarity markings, then power on the tester and open the KONNWEI smartphone app. Pair the device via Bluetooth if prompted and select the test type in the app. Perform a resting voltage measurement or initiate a cranking test as directed by the app; results and interpretation will appear on the phone screen. After testing, remove the clamps and store the unit in a dry place. Always follow vehicle manufacturer safety guidance and ensure the ignition is off unless a cranking test is specifically requested by the app.
Usage recommendations
For accurate readings, allow the vehicle to sit idle for several minutes before taking a resting voltage measurement and avoid charging the battery immediately prior to testing. Use the KONNWEI BK100 with compatible smartphones that meet the app requirements and ensure clamps have secure contact with clean terminal surfaces. When tests indicate low health or insufficient cranking performance, plan a professional inspection and consider battery replacement to avoid starting failures.
