🥇【Upgrade BM550 PLUS Design】KINGBOLEN BM550 PLUS battery tester adopts advanced circuit design, It can test all 6v 12v 24v 100-2000 CCA car batteries, including Regular Flooded, AGM Flat Plate, AGM Spiral, GEL and EFB batteries. The HD color screen design can provide clear display effects when used in low light or at night.Real time vehicle Voltage Waveform detection battery analyzer for cars trucks SUV ATV boats motorcycles etc.(Deep cycle batteries are not supported)

🥇【Multifunctional 12v Battery Tester】KINGBOLEN BM550 PLUS car battery analyser can quickly and accurately display multiple data of car battery and the results based on the CCA standard. It can test the SOH (state of health) and SOC (state of charge) of the car battery, resistance test and voltage test, besides, it can also go to the load test, start-up test, ripple test and battery level de-reading.

🥇【Real-time Voltage Waveform Monitor】This compact car battery analyser can identify faulty car batteries. It can detect real-time changes in the car voltage waveform in a data graph. The measurement results (displaying the maximum, minimum and current voltage values) show you the voltage of the battery is normal and replaced. In addition, the data graph supports recording, storage and playback.

🥇【Protection Against Reverse Connection】 KINGBOLEN BM550 PLUS car battery tester is protected by reverse polarity. If you accidentally connect the two wires upside down, don't worry, the battery tester will not work at this time to prevent the internal circuit from burning out, which can well protect the long-term use of the device and the car battery.

🥇【Warm tips】1. The motor must be switched off for testing. 2. this device does not require a built-in battery. 3.If you test with a dead battery, please charge the battery. 4.If the text display flashes on the screen, it means that the battery terminals have not properly clamped the positive and negative terminals of the battery and are connected upside down, and the device will not work.
