Battery tester FNIRSI BTM-24

The FNIRSI BTM-24 is a portable multifunction car battery tester designed for fast and accurate diagnostics of 12V and 24V batteries. The instrument features intuitive operation and a colour 2.4" TFT display that clearly shows the measured values.

Main functions and measurement options:

Comprehensive battery analysis: measures voltage, internal resistance, state of charge (SOC) and total battery life (SOH).
Starting and charging test: Evaluates the vehicle's starting ability (cranking test) and alternator functionality (charging test) under load.
Battery Types: Compatible with conventional lead acid (flooded), AGM (spiral and flat), GEL, EFB and lithium batteries.
Two testing modes: allows for both in-vehicle and stand-alone (benchtop) measurements.
Supports common international standards such as CCA (0-2000 A), IEC, EN, DIN, JIS and GB.
