Scientifically Analyze Battery Performance

  • True constant current battery capacity test with results graphically displayed, constant power testing supported with Extended software upgrade
  • Discharge current is software and electronically regulated using a solid state switch and fan cooled electronic load
  • Test any type of battery; coin cell to automotive or larger. Presets for NiCad, NiMH, Lead Acid, Li Ion, Li Poly, Alkaline, Carbon Zinc, Mercury etc.

Perform Fast, High Power Testing

  • Tests quickly at real world load conditions, up to 150 watts or 40 amps maximum, whichever is higher
  • High voltage testing at up to 55 volts; the equivalent of 1 to 38 NiCad or NiMh cells
  • Optional 500 watt and 1000 watt amplifiers

Accuracy and Precision for Demanding Applications

  • On-board computer performs accurate measurement with 12 bit effective resolution. Auto ranging for 2 current ranges and three voltages
  • Each CBA is individually calibrated with a computerized calibration system
  • Calibration certification data provided with CBA III Pro

Built-in Safety Features Provide Superior Battery Protection

  • Fail safe: automatic protection of temperature, current and power
  • Discharge test current user selectable from 0 to 40 Amps
  • Automatic voltage shut off at end of test using a software recommended or user selected safe discharge voltage
  • Automatic over-temperature shut off at end of test at using a software recommended or user selected maximum temperature with optional external magnetic temperature sensor.

Easy-to-Use Software for Data Analysis

  • User selected battery cell chemistry, number of cells and test current
  • Software recommends safe tests based on user supplied battery information
  • Automatic graph setup and scaling
  • Measures and displays voltage, current, amp-hrs, watts and temperature*
  • Easy overlay comparisons of multiple graphs may be displayed saved and recalled
  • Save, display and print battery test graphs and battery labels
  • Plug and Play high speed USB interface, with easy to use and intuitive Windows® software supplied on CD ROM

* Requires optional temperature probe

CBA III Extended Software Upgrade License Unlocks Features for Serious Battery Testing

  • Support for operation with one or two CBA 500 watt amplifiers
  • Programmable automatic duty cycle test with up to 999 second on/off cycle periods
  • Regulated constant power discharge (current goes up as battery voltage drops)
  • Temperature graphing with a recovery time option
  • Ragone power density charting using battery weight (used for performance comparison of energy sources charting energy density (Watt-Hours/kg) vs power density (W/kg))
  • Test-lead resistance voltage calibration utility to give higher accuracy voltage readings right at the battery terminals
  • Enables placement of user notes on graphs

Multi CBA Software Upgrade License for Production Testing of Batteries

  • Single computer license for up to twelve CBA IIIs
  • Simultaneous battery testing saves valuable technician time

Powerpole® Connector Features & Benefits
  • Genderless Housings: Provide simplified assembly and minimize the number of components
  • Stackable Modular Housings: Available in four sizes to right size your connection need
  • Connection Versatility: Contacts for wire, PCB, or busbar all fit into the same housings
  • Low Resistance Connection: Silver or tin plated contacts inside housings that strongly force the contacts together
  • Color Coded Housings: Help ensure that connectors are assembled and mated correctly
  • Self Securing Design: Stainless steel springs create a robust force between the contacts that holds the connector in the mated condition, but allows it to be quickly disconnected.
