Battery Tester Internal Resistance Voltage Temperature Measurement

Product Overview

This portable battery testing system combines AC four-terminal internal-resistance measurement, DC terminal-voltage measurement, and temperature measurement in one controlled inspection instrument. It supports low-resistance measurements from 0.000 mOhm to 3.100 Ohm, allowing technicians to identify connection degradation, abnormal cell behavior, and battery condition with resolution appropriate to detailed maintenance and quality work.

The equipment is suited to battery maintenance, incoming inspection, production-line verification, laboratory evaluation, and service operations involving individual batteries or battery-connected terminals. Its ability to capture resistance, voltage, and temperature as a measurement set gives engineers a practical basis for checking electrical condition while accounting for thermal operating context.

Built for indoor professional use, this unit operates across 0 C to 40 C and is specified for pollution degree 2 environments up to 2000 m altitude. USB 2.0 communication, optional wireless communication capability, a protected enclosure configuration, and a three-year product warranty support dependable deployment in recurring inspection workflows.

Key Features

• Three-Parameter Battery Assessment: The system measures battery internal resistance, DC terminal voltage, and temperature. Recording these related parameters together helps maintenance and quality teams evaluate electrical condition with more useful context than voltage-only checks.

• AC Four-Terminal Resistance Method: Resistance is measured using an AC four-terminal test method, reducing the influence of lead and contact resistance compared with two-wire measurement approaches. The open-terminal voltage is limited to 5 V maximum peak, while measurement current is selected by the active resistance range.

• Fine Low-Resistance Resolution: The 3 mOhm range provides 1 microohm resolution up to 3.100 mOhm. This capability is valuable where small changes in interconnect, terminal, or battery resistance need to be detected during preventive maintenance or acceptance testing.

• Four Purpose-Built Resistance Ranges: Selectable 3 mOhm, 30 mOhm, 300 mOhm, and 3 Ohm ranges cover measurements from very low-resistance battery paths through higher-resistance circuit conditions. Measurement currents span 1.6 mA to 160 mA according to the selected range.

• Controlled 1 kHz Test Signal: Resistance measurement uses a 1 kHz test frequency with a stated tolerance of plus or minus 30 Hz. When noise-frequency avoidance is enabled, the stated frequency tolerance is plus or minus 80 Hz, helping users configure testing around electrically noisy work areas.

• DC Voltage Measurement to Plus or Minus 60 V: The equipment measures DC terminal voltage in 6 V and 60 V ranges, with a maximum display of plus or minus 60.00 V. The input is intended for DC only; AC input is not permitted at the measurement terminals.

• Integrated Temperature Measurement: A platinum temperature sensor input supports measurement from -10.0 C to 60.0 C with 0.1 C resolution. Compatible clamp-type test leads and temperature probes allow temperature to be assessed alongside resistance and voltage results.

• Fast Measurement and Display Response: The stated measurement time is 100 ms, the display updates three times per second, and the stated response time is approximately 1.6 seconds. Resistance, voltage, and temperature are handled as one display-update group for consistent review.

• Professional Connectivity: A USB mini-B interface provides USB 2.0 CDC-class communication for connection to compatible host systems. The unit also accepts an optional wireless communication module, allowing users to extend data-transfer options without changing the core tester.

• Portable Power and Protected Configuration: Eight AA alkaline batteries support approximately 8.3 hours of continuous use without the wireless module, or approximately 8.2 hours with wireless communication enabled under the stated reference conditions. The specified dimensions include the fitted protective case, supporting practical handling during field inspections.
