BT105 12V 24V Car Battery Tester with 800 Test Records & Data Print via USB, Digital Automotive Load Tester, Cranking & Charging System Analyzer, Voltage Meter for Cars Trucks SUVs RVs Boats

The FLUTREE BT105 is a professional battery and electrical system analyzer designed for 12V and 24V lead-acid batteries (100-2000 CCA), compatible with Flooded, AGM, GEL, and EFB types for cars, trucks, RVs, and boats. Unlike basic testers that only show numbers, it features exclusive real-time waveform display that visually captures cranking voltage drops and charging ripple patterns, helping you detect intermittent starter failures, weak alternator diodes, or unstable charging instantly. Equipped with industrial Kelvin 4-wire clamps and advanced conductance technology, it delivers 99.8% accuracy in measuring SOH, SOC, CCA, voltage, and internal resistance. The 3-in-1 system performs battery, cranking, and charging tests with clear Good/Charge/Replace results. Built-in reverse polarity protection ensures safe operation. Save and print up to 800 test records via USB, enjoy free firmware updates via USB-C, and choose from 14 languages. Every BT105 comes with a 1-year warranty and lifetime customer support.
