FNIRSI BTM-24 - battery tester

> 12 V/24 V Battery Analyzer: FNIRSI BTM-24 car battery tester supports CCA 0–2000 A, accurately measures battery health (%), voltage, and internal resistance, and performs cranking, load, and charging diagnostics to ensure reliable battery performance and vehicle operation.

> Wide Application: Suitable for cars, trucks, SUVs, RVs, ATVs, motorcycles, boats, and more; supports Regular Flooded, AGM Spiral/Flat, GEL, EFB, and LAB/EV LAB batteries; meets CCA, IEC, EN, DIN, JIS#, and GB standards for reliable diagnostics.

> Smart Battery Load Tester: Battery test shows voltage, internal resistance, and health (%) as “Good/Fair/Low.” Cranking checks engine start. Load monitors min and dynamic voltage; charging tracks min, max, and dynamic voltage, both with waveform views for easy monitoring analysis.

> Enhanced Safety Protection: Battery tester features reverse polarity and overvoltage protection, with upgraded insulated clamps that isolate conductive metal parts to prevent reverse connection damage, short circuits, and electric shocks.

> User-Friendly: Features a 2.4-inch color screen with day/night UI themes, integrated cables to stay secure, a foldable stand for stable support and easy storage, rear wall-mounting option to save space, and a Type-C port for firmware update.
