Key Features & Specifications

  • Measures and records cell self-discharge current & voltage using the BT2152A Self-Discharge Analyzer
  • Controls the analyzer’s channel configurations, measurement settings, test duration.
  • Saves or logs measurement data on all channels (current & voltage), and temperature on the group of up to 32 cells..
  • Recalls previously stored measurements for display and analysis.
  • Exports recorded data to csv file.
  • Matching function measures initial cell voltage & current, and adjusts values for faster self-discharge measurement.
  • Allows the user to adjust the effective total resistance value in series with the cell. This allows the user to select a total resistance value to optimize the RC settling time of the measurement.


The Keysight BT2155A Self-Discharge Analysis Software, controlling the BT2152A Self-Discharge Analyzer, measures and records Li-Ion cell self-discharge current and cell voltage. The software configures the analyzer’s channel settings, such as initial voltage & current matching, channel limits (OVP, OCP, UVP), measurement intervals, and test duration.

The combination of the BT2155A & BT2152A delivers a revolutionary reduction in the time required to measure cell self-discharge current. For smaller cells like cylindrical 18650 or 21700 cells, testing indicates that you can quickly determine stable self-discharge current in as little as 30 minutes to 2 hours, depending on the cell characteristics. For larger capacity pouch cells (e.g., 10-60 Ah), this can take as little as 1-4 hours.

That‘s a significant improvement compared to waiting weeks or months for the cell open circuit voltage (OCV) to change enough to determine cell quality. That can provide a major reduction in work-in-process inventory and floor space required for cell storage. And it can significantly decrease your test cycle time and improve your time-to-market.

The Self-Discharge Analyzer and Software quickly measures self-discharge current using a potentiostatic measurement method with the characteristics needed to accurately make the direct current measurement. The BT2155A Self-Discharge Analysis Software controls one BT2152A Self-Discharge Analyzer (up to 32 channels), and also measures the temperature on a group of up to 32 cells.
