KONNWEI KW750 battery tester can check the overall operating status of 6V 12V 24V 36V 48V 60V 72V battery. Battery testing can analyze the battery healthy status to calculate the actual cold cranking capability of the battery and the aging extent. Cranking test helps you test and analyze the starting motor, and the charging test is to check the charging system status to avoid damaging the battery.
KONNWEI KW750 battery tester built in printer, equipped with standard thermal printer paper, can print the last test result of this battery tester directly. After the test is completed, you can easily print the test results, the paste it on the worksheet.
Support the majority of vehicle battery standards, such as CCA, BCI, CA, MCA, JIS, DIN, GB, ICE，EN，SAE Suitable for all 1V-72V lead-acid batteries ranging from 100 to 3000 CCA, including regular flooded, AGM flat plate, AGM spiral, GEL, and EFB and lithium batteries for the truck, boat, Car, motorcycles, lawn mowers and other gardening machines, etc.
This car battery load tester offers vehicle electrical safety through exceptionally polarity reverses connection protection. Fully Insulated Alligator Clips are built with user safety in mind through spark free operation and reverse polarity protection. This
car battery tester is easy-to use and can get accurate results is seconds. The battery alternator tester can directly detect bad cell battery and test the battery that is losing power (as low as 1.0V), no need to full charge before testing. No matter the batteries in the vehicles or out of the vehicles, the KONNWEI KW750 battery tester will finish its testing job excellently.
Special Functions:
(1). Current detection in battery leakage testing focuses on measuring abnormal currents (leakage currents) —either internal or external—to assess the battery’s insulation integrity and identify potential safety risks. Production Quality Control: On battery production lines, it quickly detects micro‑pores or poor sealing in cells or packs. Equipment Maintenance: In automotive repair, it measures the quiescent current when the vehicle is in sleep mode to identify abnormal battery drain.
(2). The clamp‑integrated temperature sensor ensures that all diagnostic parameters (voltage, resistance, CCA, and leakage current) are corrected using the battery's real terminal temperature, making the "GOOD/BAD" verdict truly reliable and eliminating the guesswork of ambient temperature readings.
