Universal Conditioning Chargers

The Cadex Universal Conditioning Chargers (UCC) offer refinements usually not found on competitive chargers. The rugged design stands up to the critical demands of industrial users. Intelligent adapters allow simultaneous service of nickel-cadmium, nickel-metal-hydride and lithium-ion batteries on the same platform. A conditioning button conditions and calibrates batteries on demand, and a reverse-pulse charging prolongs battery life.


Cadex UCC 1

This compact single-bay battery charger assures freshly charged batteries in the office and on travel. The UCC 1 comes with a 60-watt universal AC power supply for all global voltages.
Part Number: 11-302-0100

Cadex UCC 2

Cadex UCC 2 The two-bay charger is designed for desktop, wall mount or vehicle use. The AC version comes with a 60-watt universal power supply. When used in a vehicle, a DC-DC converter regulates the 12VDC input voltage to assure proper charging.
Part Number: 11-302-0200

Cadex UCC 6

Cadex UCC 6 The six-bay charger is suited for desktop or wall mount and features an internal 100-watt universal power supply with detachable cord.
Part Number: 11-302-0600


Individual charger modules

Each bay includes a UCC module that charges lithium and nickel-based batteries from 3.6V to 15V at 15W and 25W. The charge currents range from 50mA to 3A at an input from 12VDC to 36VDC. This enables charging a 15V battery in a 12V vehicle. Open Frame Battery Charger Module


The adapters contain a battery code that configures the charger to the correct battery parameter. This allows maximum flexibility in charger configuration. Nickel-cadmium, nickel-metal-hydride and lithium-ion batteries can be serviced side-by-side. Smart Battery Adapters


Redundant algorithms provide safety even with a known defective battery. Incorrect battery voltage, mismatched cell and temperature extremes halt the charge by alerting the user with a red fail light. This feature protects the battery and charger.

Cold charging

When charging at cold temperatures, the UCC charger applies a gentle trickle charge to warm up the battery, then switches to fast-charge at operating temperature. A charge time-out prevents a prolonged charge if the temperature does not rise. Charging Batteries in Cold Temperature

Hot charging

Should the temperature of a nickel-based battery reach the upper threshold level, the UCC allows the pack to cool before resuming at half the previous charge current. If the temperature threshold is reached again, the current is lowered further to reduce heat related battery damage. Hot Temperature Charging

Light signals

Safety and redundancy are key in charger design. Advanced algorithms terminate the charge on incorrect voltages, mismatched cells and temperature extremes. RUN, READY and FAIL signals provide status.

Calibration Discharge

Intelligent batteries need a periodic full discharge for calibration, and nickel-based batteries should be exercised every three months to prevent memory. The discharge function of the Butterfly provides these services on command.

Reactivating lithium-ion batteries

The UCC wakes up seemingly dead lithium-ion packs by applying charge pulses to reactivate the safety circuit. A full charge commences when the battery reaches a safe charging voltage. Boost Li-ion Batteries

Full-charge termination

Full-charge detection of nickel-based batteries occurs on negative voltage slope, rate of temperature increase and/or a rapid temperature change (dT/dt). Lithium-ion terminates the charge on voltage plateau and current saturation.

Conditioning discharge

A condition button allows discharge on demand to reverse memory and regain lost performance. Nickel-cadmium batteries require monthly service; nickel-metal-hydride should be discharged once every three months. The condition cycle also calibrates batteries with fuel gauge. Conditioning Discharge


The UCC charger intersperses discharge pulses between charge pulses to improve charge acceptance on nickel-based batteries. This method promotes the recombination of oxygen and hydrogen gases generated during charge. This results in faster charge times, better battery performance, reduced memory and longer service life.

Full UCC System Enclosed in IP67 Transit Case

  • Custom Configuration: Adapter combination on the 6 bays is configurable to mission needs.
  • Highly Portable: Easily carry the transit case wherever the mission takes you.

* Adapters are shipped seperately and may be installed in the required combination
before deployment. If Cadex does not have an existing adapter for a battery model, a
cutom adapter design can be requested for the battery with additional engineering fee.

Battery Testing Range

  • Battery Types: Lithium and Nickel based
  • Li Charge Voltage: 4.1, 4.2, 12.3, 12.6, 16.8V Configurable within custom adapter
  • Ni Charge Voltage: Up to 16.8V (suitable for charging up to 10.8V nominal)
  • Charge Current: 3A Maximum up to 25W/bay
  • Charge Power: up to 25W per bay
  • Discharge Power: 5W max per bay, conditions and calibrates battery on command
  • Condition Cycle: A condition cycle will consist of a sequence of Charge -> Discharge -> Charge. This cycle can be used to re-calibrate the fuel gauge on a Li-Ion battery or reverse memory and regain lost performance in a NiCD battery.

Battery Interface

  • Battery Bays: 6 bays supporting simultaneous service of each battery
  • Battery Interface: Factory or field installed custom adapters with configuration code stored within adapter. Configuration code determines charge and discharge parameters. Cadex has developed approximately 50 unique adapters for the UCC family of chargers. In addition, Cadex has over 2000 adapters for the C7 family. C7 adapters can generally be modified for use on the UCC and if an adapter for a battery is not available a new custom adapter can be developed.
