C8000 Battery Testing System. Affordable lab-grade accuracy and power.

Whether validating cutting edge lithium battery research or quanitfying the energy needs of a new battery-powered IOT device, the C8000 may be the most complete battery testing system available.

The Cadex C8000 stands in a class by itself in flexibility and affordable price. Test SMBus batteries, monitor cell balance and capture load signatures to observe batteries with a unique load protocol. Add a thermal chamber, an external load bank, a safety circuit and alarm to form a command center and you begin realizing the unique qualities of this fine battery testing system.
  • 4 independent digital drivers for maximum flexibility
  • 1.2V – 36V, 10A charge and discharge per channel
  • 100W per channel on charge; 80W on single channel discharge, 160W dual channel, and 2400W with external load bank
Part Number: 11-308-0000


Digital technology widens the test range, provides ultimate stability and gets more power into a compact housing than is possible with analog devices. Each channel can be programmed with up to 10A charge and discharge current each. Power handling is 100W per channel on charge and 80W on discharge, or 400W on charge and 320W on discharge on all four channels.

The Cadex C8000 is more than a programmable power supply and load bank; the instrument has intelligence to assist in safe battery testing. Protected charge and discharge algorithms with redundant safety features identify a faulty battery and safely terminate the service should an anomaly occur. The system can be overridden for destructive tests.

Separate Battery and I/O Ports

Each channel features a Battery Port and I/O Port for individual programming. The system includes:
  • Positive/negative input; 4-wire Kelvin
  • Analog thermistor input
  • 4 differential analog voltage inputs
  • 2 analog outputs
  • 4 input/output control for switching
  • SMBus, clock, data for smart packs

Monitoring individual cells

Four differential (floating) analog inputs enable voltage check of up to 5 cells; 4 direct and one by voltage extraction. Monitoring Individual Cells

Load Capture

With the Load Capture Unit, the Cadex C8000 takes load signatures and plays them back as a simulated load protocol to check battery runtime in the lab. Check the battery runtime with different load demands and battery types. The C8000 goes to 10A; an external load bank brings this up to 240A. Building a Laboratory System

external load bank

For higher load currents on discharge, you can connect the C8000 to a designated external load bank, enabling loads of up to 2,400 watts and 48 volts. (Supported on one channel only).

See Specifications for listing

Dual Power Port Cable

The Dual Power Port Cable ties two channels together to double the current from 10A to up to 20A. Applicable on discharge only. C8000 Dual Power Port Cable

Smart Battery testing

The Cadex C8000 reads register settings of SMBus batteries to verify function and identify anomalies.
  • Assists in the design of smart batteries
  • Checks cell voltages to verify proper function
  • Reads Full Charge Capacity (FCC)
Smart Battery Testing


The Cadex C8000 allows testing batteries under GSM, CDMA or other discharge protocols. Programming is in 50μs intervals and the minimum setting is 500μs.

Runtime discharges a battery under three load conditions. You can set time duration and load levels. The cycle repeats itself until the capacity drops to the target setting. PC-BatteryLab™ provides charts and stores the results.
Load Test


The program verifies battery endurance by counting the cycles until the capacity drops to the target capacity. This helps select a battery and do incoming inspections to ensure consistent quality. The program is fully automated; PC-BatteryLab™ displays and stores the test. Lifecycle Test

Service Programs

The automated programs are grouped into Basic, Advanced, Rapid-test and Custom programs.

basic Programs

Charge Applies fast charge; trickle when applicable.
Auto Exercises batteries with charge-discharge-charge. Applies recondition on nickel-based batteries to reverse memory if user-set target capacity cannot be reached.
Prime Prepares batteries with discharge-charge-discharge by repeated cycling until maximum capacity is reached. The first reading is the spare capacity before charge.
Extended Prime 16-hour trickle charge prior to Prime. Prepares difficult to charge batteries
Boost Activates batteries that became deactivated due to low discharge.

Advanced Programs

Load Test Tests batteries under simulated GSM, CDMA and other discharge protocols, 50μs steps; minimum setting 500μs.
Runtime Allows three different discharge levels; programmable in hours and minutes.
Lifecycle Cycles battery until the performance drops the target capacity.
Self-Discharge Measures self-discharge. Identifies stresses leading to compromised safety.
Discharge Only Prepares battery for storage. Also checks charger function.
Load Capture Simulates real life conditions with pre-recorded load. Requires PC-BatteryLab™ and Load Capture Unit to record load signature.


OhmTest™  Measure battery resistance with DC pulses 13 seconds; based on IEC61436.
Impedance  Measures battery resistance with 1000Hz signal. Channel 1 only.
Note: Readings of a reactive device differ with DC and AC test methods.

Custom Programs

These programs allow user-defined settings of charge, discharge, recondition, wait and repeat. You can set conditional gates that proceed on a different course if certain criteria are met. Custom works with PC-BatteryLab™ and has a limit of 100 user-defined programs.
One of the critical applications of the custom program is preparing a battery for shipping. You may also want to prepare a battery for storage.

Note: Supervision recommended in the absence of automated terminations.
