FNIRSI BTM-24 Multifunctional Car Battery Tester with Bluetooth 5.0, 6V/12V/24V, Lead-Acid/AGM/GEL/EFB/LiFePO4, CCA 100-2000, Conductance Test, Reverse Polarity Protection

The FNIRSI BTM-24 is a professional multifunctional car battery tester designed for accurate diagnosis of 6V, 12V, and 24V batteries. It supports a wide range of battery types including Lead-acid, AGM (Flat Plate, Spiral), GEL, EFB, and Lithium (LiFePO4). With Bluetooth 5.0 connectivity, it pairs with your smartphone (Android 5.0+ / iOS 9.0+) to provide comprehensive test results via the dedicated app. The tester uses advanced conductance technology to measure battery health (SOH), state of charge (SOC), internal resistance, voltage, and CCA value. It also performs cranking and charging system tests, voltage monitoring, and ripple detection. Built-in reverse polarity protection ensures safe operation. The compact design with a 50 cm cable and ABS plastic housing makes it durable and easy to use in workshops or at home.
