Meet the SL101XA | SL1133A Battery Test System Cell Level Series

The cell is the basis of every energy storage device and has a direct influence on the quality of the battery modules and packs. It is essential to characterize the cells during an early development phase. The Cell Level Series (SL1002A, SL1003A SL1004A, SL1005A, and SL1133A) – also known as Battery Cell Tester – emulates sink and source for battery modules for automotive and industrial applications.

  • Efficient and cost-effective operation because of recovery capabilities for endurance tests with many channels
  • Modular configuration – any number of channels adapts to changing requirements
  • Convenient control and monitoring temperature or climate chambers with the Scienlab software ESD
  • Compact size for space- saving on-site operation
  • Integrated electrochemical impedance spectroscopy (EIS) per channel – programmable directly into the test processes without changing the contacting of the DUT (optional)


The cell is the basis of any energy storage system and directly influences the quality of battery modules and packs. It is essential to test the cell at an early stage and to characterize their developmental to design functions. For this purpose, Keysight offers reliable test systems for precise and reproducible measurement results to evaluate the properties of future systems and develop battery models.
