BM550 PLUS 6V 12V 24V Car Battery Tester with LED Display, 100-2000 CCA 2-200Ah Automotive Alternator Digital Battery Analyzer for Car/Truck/Motorcycle/ATV/SUV/Boat/Yacht -

【Plug and Play】 It's very easy to use; simply connect the battery tester's clip correctly to the car battery, and you can start working. The cold cranking amps (CCA) and Ah input are adjustable to suit batteries of all sizes and power levels. It's ready to use right out of the box, with a simple user interface, and you can quickly measure results. It can be tested whether the battery is in the vehicle, outside the vehicle, or dead. It doesn't need batteries, as it's powered by the battery being tested. 【Upgraded BM550 PLUS Battery Tester】 The BM550 PLUS car battery tester can test all 6V, 12V, and 24V car batteries with 100-2000 CCA ratings, supporting 2Ah-220Ah (you need to enter the corresponding CCA rating on the battery). It can test normal batteries, flat AGM batteries, spiral AGM batteries, GEL and EFB batteries, truck batteries, and more (not suitable for deep-cycle batteries). It also features waveform monitoring for a more intuitive view of the battery's condition. 【Reverse Connection Protection】 The battery tester has a safe design. If you accidentally reverse the two wires, don't worry, the battery tester will not operate to prevent damage to the internal circuitry, thus protecting the equipment and ensuring the long-term use of the car battery. (If the clip is not securely attached, the screen will flash.) A simple and effective tool designed for DIY enthusiasts, automotive factories, garages, car battery manufacturers, and more. Start your testing now! 【Multifunctional Battery Tester】 The BM550 PLUS car battery analyzer can quickly and accurately display data and results for multiple car batteries based on the CCA standard. It can test the SOH (State of Health) and SOC (State of Charge) of the car battery, easily test internal resistance, and perform a 100-2000 CCA voltage test. With our battery tester, you can easily understand the current state of your car battery and prevent accidents. A handy little tool to have in your toolbox. 【Real-Time Voltage Waveform Monitor】 This compact, handheld analyzer helps identify faulty car batteries. It can detect real-time changes in the car's voltage waveform. Measurement results (maximum, minimum, and current voltage values) can be quickly and accurately displayed on the 1.8-inch high-definition color screen, allowing you to easily analyze the data and determine if the car battery needs replacing. The BM550 PLUS 100-2000 CCA 6V 12V 24V car battery tester is compatible with cars, trucks, SUVs, ATVs, boats, and motorcycles. It checks all 6V, 12V, and 24V CCA car batteries, including standard flooded, AGM flat plate, spiral, and GEL EFB batteries. It quickly and accurately displays the test status: voltage, resistance, SOC, and SOH. Plug and play; simply enter the voltage into the tester to perform a quick test. Test results are based on the CCA standard. The LED color screen design provides clear display effects when used in low-light conditions or at night. It detects real-time changes in the vehicle's electrical system. It allows for testing both inside and outside the vehicle without removing the battery. It features reverse connection protection. The "Good" indicator means the battery is ready for use. "Normal" means it can still be used. "Bad" means it needs to be replaced. The adjustable cold cranking amp (HCA) input amperage (AH) accommodates all power levels. The display provides a quick and accurate test. The SOH (Season of Health) indicator will show the battery's health status after the test report is displayed, indicating whether it needs recharging, retesting, or replacement. SOC (State Charge) Voltage (Battery Voltage) R (Resistance) STD (Standard Battery Capacity) Test: Determines exact parameters, setting benchmarks accordingly. Test charge: Start the engine and test state. The test indicates milliseconds so you can predict if the vehicle will discharge. Test: Charged voltage measured when on-board electrical devices are switched on. Note: Complies with JIS, EN, GB, CA, DIN, SAE, BCI, MCA, and IEC standards. Real-world monitoring. Enables intuitive battery understanding. Equipped with a protector that will not damage the battery even when connected to the positive and negative terminals. Tip: If connected backwards, it will not light up. If contact is made, the CLIP ERROR message will illuminate. Wide range of applications: Tests 100-2000CCA, normal flat, spiral, and EFB batteries. Suitable for land, sea, motorcycle, ATV, SUV, and boat vehicles. User Guide: STEP 1: Connect correctly and select type (if clip is not attached, it will flash). 2: Enter value (operates 100-2000CCA). 3: Displays relevant life data (Determine necessary maintenance, replacement, and function testing). Supports 10 languages: English, French, Spanish, Italian, Portuguese, Russian, German, Polish, Japanese, and Chinese.
