Comprehensive Battery Test Results

The KINGBOLEN BM550 battery analyzer uses the latest conductance testing method to evaluate battery performance accurately.

It provides important battery information, including:

Battery Voltage
Cold Cranking Amps (CCA)
State of Health (SOH)
State of Charge (SOC)
Internal Resistance

Based on the CCA standard, the test results help you quickly check the current condition of your battery and determine whether further inspection or replacement may be needed.

Fast Testing with Reliable Accuracy

Equipped with a built-in intelligent microprocessor, the BM550 delivers fast battery testing and displays results within seconds.

With a testing accuracy of up to 99.5%, it provides reliable measurement results for everyday battery checks, helping users quickly identify battery performance status.

Wide Battery Compatibility

The BM550 supports multiple types of 6V, 12V, and 24V lead-acid batteries, making it suitable for various automotive applications.

Compatible battery types include:

Lead-Acid Batteries
AGM Flat Plate Batteries
AGM Spiral Batteries
EFB Batteries
GEL Batteries

Whether testing a battery installed in the vehicle or a removed battery, the BM550 provides a convenient way to check battery condition.

Easy Plug-and-Play Operation

Designed with simplicity in mind, the KINGBOLEN BM550 requires no complicated setup.

Simply:

Connect the clamps to the battery terminals.
The tester powers on automatically.
View the test results on the 1.8-inch HD display.

The BM550 supports both in-vehicle and out-of-vehicle testing, allowing you to check battery status conveniently at home, in a garage, or during routine maintenance.

Safe Design with Reverse Connection Protection

The BM550 features reverse connection protection to help protect the tester during incorrect connection.

If the positive and negative clamps are accidentally connected in reverse, the device will not operate, helping prevent potential damage to the internal circuit.

Note: If the clamps are not properly connected to the battery terminals, the screen may flicker. Please ensure the clips are securely attached before testing.
