FR BTM24 Car Battery Tester 12V/24V – Digital Automotive Battery Analyzer with Cranking & Charging System Test

Overview 

The FR BTM24 is a heavy-duty, professional-grade battery analyzer compatible with both 12V (Cars/SUVs) and 24V (Trucks/Buses/Generators) systems. Unlike traditional load testers that generate heat and sparks, the BTM24 utilizes advanced conductance testing technology to deliver safe and accurate results in seconds. It measures the State of Health (SOH), State of Charge (SOC), and Internal Resistance, giving you a clear “Good,” “Replace,” or “Recharge” verdict.

Key Features 

• Dual Voltage Support: Works seamlessly on 12V automotive batteries and 24V heavy-duty vehicle systems.

• Comprehensive Testing: Checks Battery Health, Cranking (Starter) System, and Charging (Alternator) System.

• Wide Battery Compatibility: Supports Regular Flooded, AGM Flat Plate, AGM Spiral, GEL, and EFB batteries.

• No Battery Removal Needed: Test the battery directly inside the vehicle without disconnecting the terminals.

• Reverse Polarity Protection: Safe for both the user and the vehicle’s ECU—no sparks or heat.

• Large Backlit Display: Clear, easy-to-read LCD for use in dark engine bays.

Technical Specifications

Why every car owner needs this? 

• Save Money: Don’t replace a “dead” battery that just needs a good charge from a faulty alternator.

• Prevent Breakdowns: Identify a weak battery before it fails completely in the heat of summer or cold of winter.

• Check the Alternator: Ensure your car is actually charging the battery while you drive.
