Standby Battery Diagnostics

PITE3915 Battery Tester

Find weak standby batteries faster with handheld voltage and internal resistance / conductance testing.

Designed for routine IEEE-style battery maintenance, PITE3915 helps technicians test every cell in a string, compare results with reference values and move from field readings to PC reports without interrupting service.

Battery capacity5-6000 Ah
Compatible cells1.2V, 2V, 6V, 12V
Voltage range0.000-16V
Resolution0.1 mΩ / 1 mV
Cells per string1-254 cells

Field Ready Kit

Built for battery rooms, UPS systems and telecom DC plants.

PITE3915 combines a rugged handheld tester, probe pins, heavy-duty test clamps and PC software into one maintenance workflow. The tester records voltage and internal resistance / conductance in seconds, saves data automatically and gives teams a practical basis for identifying degraded cells before they become system risks.

  • Color touch screen with keyboard operation for quick field input.
  • Low test frequency helps reduce capacitive resistance interference.
  • Built-in reference values and self-defined thresholds support result comparison.
  • Retest and compensation functions help correct missed or faulty operations.

Review results on PC

Transfer data by USB drive, review cell status and keep maintenance records organized by site and string.

DataView Software

Turn field readings into clear reports.

The included DataView software uploads test data from the USB drive, groups records by site and string, displays table and graph views, and exports reports directly to Microsoft Excel.

  • Status chart for Good, Pass, Warn, Failed and Abnormal cells
  • Voltage, resistance and capacity result tables
  • Histogram view for fast outlier comparison
  • Excel report export for maintenance documentation
