Improvement/Enhancement on CBA IV, Capabilities, 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. pre-sets for NiCad, NiMH, Lead Acid, Li-Ion, Li-Poly, Alkaline, Carbon Zinc, Mercury, etc.
Solar cell profiling capability * Lower current testing capabilities - down to 10 mA,

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 IV Pro Built-in Safety Features Provide Superior Battery Protection Failsafe: automatic protection of temperature, current and power * Safety watchdog stops a discharge in the event of a computer crash.

Discharge test current user selectable from 0 to 40 Amps, Automatic voltage shut off at end of the test using a software recommended or user-selected safe discharge voltage,

Automatic over-temperature shut off at end of the test using a software recommended or user-selected maximum temperature with optional external magnetic temperature sensor.

Easy-to-Use Standard Software for Data Analysis.
