How to use

Ensure the vehicle ignition and all electrical consumers are switched off before connecting the tester. Attach the red clamp to the positive terminal and the black clamp to the negative terminal, observing correct polarity. Power on the Viking TOPDON BT300P and select the appropriate test mode if required; the device will perform an automatic assessment and display diagnostic information about cranking capacity and battery condition. After the test completes, remove the clamps beginning with the negative terminal and store the tester in a dry place.

Usage recommendations

For consistent results, test batteries at ambient temperatures close to typical operating conditions and avoid testing immediately after charging or heavy cranking. Use the tester as part of routine maintenance to detect weakened batteries early; if the device indicates low cranking capacity or poor condition, follow with a full charging cycle and a secondary test or consult professional service for further evaluation.
