6V 12V 24V Battery Tester: The BM550 Battery Tester can test all 6V 12V 24V 100-2000 CCA car batteries, supporting 2Ah-220Ah (must input the corresponding CCA value of the battery), including battery analyzer for normal batteries, flat plate AGM batteries, spiral AGM batteries, GEL and EFB batteries, car-trucks, etc. (Not suitable for deep cycle batteries).
Plug and play: The BM550 battery tester is easy to use, just connect the battery tester clamp to the car battery correctly and start working, whether the battery is inside or outside the car, or even a dead battery can be tested.
Practical Car Battery Analyzer: The BM550 car battery tester can quickly and accurately display a wide range of data from a car battery. It can test the SOH (State of Health) and SOC (State of Charge) of the battery, easy 100-2000 CCA, internal resistance test, and voltage test. With our battery tester, you can easily keep an eye on the current condition of your car battery and avoid accidents.
Easy to use and accurate data: Battery testers are based on the CCA standard and can be displayed quickly and accurately on the 1.8-inch HD screen, allowing you to quickly get an overview of the battery's status. You can test the battery inside and outside the car, very convenient.
Fast and accurate >99.5%, Reverse Polarity Protection: The BM550 battery tester is 99.5% accurate thanks to the built-in intelligent microprocessor, and test results can be displayed in less than two seconds. At the same time, the BM550 has reverse polarity protection to prevent the internal circuit from burning out, which can well protect the equipment and car battery for long-term use.
