NH Research Battery Cycler for R&D and Production Lab Testing - NH Research (NHR)


NHR’s Battery Cycler (9220) has low voltage and high current, designed for testing all battery chemistries including lead-acid, lead-cadmium, and other low voltage, high current, large format batteries (LFB) typically used in energy storage systems (ESS). This battery cycler is bi-directional requiring no additional equipment to charge or discharge the unit-under-test (UUT). Additionally, the built-in measurement system eliminates external measurement devices by providing time-stamped digital readings for voltage, current, power as well as Ah and kWh.

NHR’s battery cyclers cover a wide-range of applications such as EV, solar PV, aerospace, energy storage, and industrial power industries. The 9220 Series is a fast-acting, fully programmable, and bi-directional DC source (charge) that provides reversible current flow in order to act as a regenerative DC load (discharge).

Additional NHR Battery Cyclers include:


  • Low voltage/high current battery cycler
  • Designed for testing all battery chemistries including:
    – Lead-acid
    – Lead-cadmium
    – Other low voltage, high current batteries
  • Multiple safety layers to protect battery/DUT


  • Regenerative, returns greater than 87% of power to the facility, which provides significant electrical savings.
  • Bi-directional DC Source requiring no additional equipment to charge or discharge the unit-under-test (UUT)
  • The built-in measurement system eliminates external measurement devices
  • Regenerative, recycles up to 87% discharge power back to the facility
  • System cabinet features for easy installation
