JUNXY-5320A Battery Analyzer

New JUNXY-5320A Battery Analyzer

JUNXY-5320A Battery Analyzer is the most powerful handheld storage battery tester. It is a multi-purpose resistance tester and ohm meter with the most complete functions, which can test all kinds of battery like 1.2V, 2V, 4V, 6V, 8V, 12V, 24V, 48V. It can also test resistance of conductor and metal connector, and resistance measurement resolution reaches 1μΩ.

JUNXY-5320A adapts VLSI and powerful microprocessor, and can do the data exchange with RS232 and RJ45 port. Meanwhile, it adapts the large screen colorful LCD, and can do the analysis, display and report for test data. It is an indispensable tool for network operators and power department etc.

  • Various types of battery testing, including 1.2V, 2V, 4V, 6V, 8V, 12V, 24V, 48V, voltage testing range 0-60V Various test modes, single testing and auto real-time testing.
  • Keyboard operation, 3.5" TFT LCD color with backlIt, and support multilingual display
  • Built-in chargeable Li-ion battery, more than 5 hours operation time.
  • Large data storage capacity, more than 100,000 records


  • Storage battery resistance testing: automatically switch within the test range 1μΩ--400Ω, and resistance measurement resolution reaches 1μΩ.
  • Conductance testing for pure conductor and the battery connecting unit, conductance, i.e. reciprocal of resistance.
  • Support remote control through RS232 and RJ45 port, and transmit the test data to the remote end to analyze and store.
  • Record the charge and discharge capacity of battery string, it is an ideal tool for researching and analyzing the battery functions and efficiency.
  • Permanent storage of 10000 groups battery parameters, and each string includes 500 batteries at most.
  • Test result can be compared to user-defined alarm setpoint values, and support permanently 1000 types of such data.
  • Automatically establish the test data for the single cell and battery string which enormously facilitate to generate the record of battery string with multiple single cells, no matter battery string with 24 or with 108 single cells.
  • Directly generate and display the battery string single cell test report and distribution curve graph.
  • On-screen pass/warning/fail indication during testing.
