Wide Compatibility
The BM550 supports 6V, 12V, and 24V lead-acid batteries with capacities between 2Ah–220Ah and cold cranking amp (CCA) ratings from 100–2000CCA. It is compatible with the following battery types:
Regular flooded (standard) batteries
AGM flat plate
AGM spiral
GEL
EFB (Enhanced Flooded Battery)
Not suitable for deep-cycle batteries.
Fast and Accurate Testing
Using advanced conductance testing technology, the BM550 measures:
SOH (State of Health) – assesses overall battery condition
SOC (State of Charge) – shows current charge level
CCA (Cold Cranking Amps) – determines cold start performance
Internal Resistance – detects battery aging and efficiency
Voltage – measures in real time for accurate readings
Test results are displayed instantly on the 1.8-inch HD backlit screen, providing clear visibility even in low light.
Plug-and-Play Operation
Simply connect the positive and negative alligator clips to the battery terminals—no external power required. The tester will automatically power up and begin diagnostics whether the battery is in-vehicle or out-of-vehicle.
Built-In Safety Protection
The BM550 is equipped with reverse connection protection, preventing damage from incorrect clamp placement. If the clips are not properly attached, the screen will flicker as a safety alert—keeping both the tester and battery safe from harm.
