Battery Internal Resistance Tester – Quick Selection Guide
Core Parameters:
Range/Resolution: 0.01–200 mΩ / ≥0.1 mΩ (0.01 mΩ for high-precision)
Voltage: 0–600 V DC (covers most UPS/comm/energy storage)
Accuracy: ±(0.5% reading+1 digit) for routine; ±(0.2% reading+1 digit) for factory/precision
Frequency: 100 Hz / 1 kHz (mainstream, stable)
Wiring: Four-terminal Kelvin (mandatory)
Power: Built-in Li-battery (0.5–1kg, ≥8h) for field; AC220V for lab
Scenario Selection:
Substations (lead-acid): 2V/12V switching, temp compensation, data storage (≥800 sets), USB export
Base/Data Center: Non-destructive, ≤5s/test, batch mode, over-limit alarm, Bluetooth/wireless
Lithium production: 0.01 mΩ resolution, multi-channel, data comparison, optional BMS integration
Outdoor: IP54+, –10°C to 40°C, EMI resistant
Function & Compliance:
Core: Data management, temp compensation, over-limit alarm, trend analysis, four-terminal Kelvin clamps
Compliance: IEC 61010 + CNAS third-party calibration report
