4. Product Features
The KINGBOLEN BM510 offers a comprehensive suite of features for battery diagnostics:
- Four Basic Battery Test Functions:
- Battery Test: Evaluates battery life, voltage, Cold Cranking Amps (CCA), and internal resistance.
- Start The Test (Cranking Test): Assesses the battery's discharge performance during engine startup.
- Load Test: Checks the engine's overall performance under load.
- Charging Test: Analyzes the engine's charging system.
- Real-time Waveform Monitoring:
- Automatically stores up to 10 waveform monitoring records.
- Allows viewing of saved waveform data.
- One-click clear function to delete all stored waveform data.
- Ripple Test: Tests the charging system of the engine. Smaller waveform fluctuation indicates more stable voltage and a good battery condition.
- Reverse Polarity Test: The device is designed to operate normally even if the positive and negative clips are connected incorrectly, preventing damage to both the battery and the tester.
- Low Frequency Constant Current Test: Applies a fixed frequency and current test signal to sample, rectify, and filter the battery's voltage, then calculates its internal resistance. This method is gentle on the battery.
- Screenshot Function: Capture and save important data with a one-click screenshot by long-pressing the "Up" and "Down" buttons simultaneously. The device can store up to 10 pictures.
- Wide Application Range: Compatible with 6V, 12V, and 24V batteries, suitable for various vehicles including cars, trucks, RVs, ATVs, SUVs, boats, yachts, mowers, and golf carts.
- Multiple Battery Type Support: Tests EPS lead-acid batteries, car start batteries, AGM/EFB start-stop batteries, electric vehicle batteries, UPS lead-acid batteries, and Gel batteries. (Note: For UPS, electric vehicle, and motorcycle batteries, only internal resistance, power, and voltage can be measured, not battery life.)
- Lifetime Free Update: Software updates are simple and easy to operate, requiring no driver installation.
