FNIRSI BTM-24 Battery Tester

Product detailed description

The FNIRSI BTM-24 is a portable, multifunctional car battery tester designed for the quick and accurate diagnosis of 12V and 24V batteries. The device features intuitive controls and a 2.4" color TFT display that clearly shows the measured values.

Main Features and Measurement Capabilities:

Comprehensive battery analysis: measures voltage, internal resistance, state of charge (SOC), and overall battery health (SOH).
Starting and Charging Test: Evaluates the vehicle's ability to start (starting test) and the alternator's performance (charging test) under load.
Battery types: Compatible with standard lead-acid (flooded), AGM (spiral and flat), GEL, EFB, and lithium batteries.
Two testing modes: allows for measurements both in the vehicle and as a standalone unit (on a workbench).
It supports common international standards such as CCA (0–2000 A), IEC, EN, DIN, JIS, and GB.
