The Cadex C7400ER is the most powerful of the C7000 Series battery analyzers. Six amps per station, service of 36 volt batteries and 170 watts of continuous power satisfies most service requirements.

  • Battery voltage range 1.2 to 36V (Li-ion)
  • Charge/discharge current up to 6A per station
  • Maximum charge power 75 watts per station
  • Maximum discharge power 75 watts

Product Description

The Cadex C7x00 Series battery analyzers are more than programmable power supplies to charge and discharge batteries; they assess the condition of a battery and provide intelligence to safely service them. Protected algorithms with redundant safety features identify a faulty battery and terminate the service with message when so needed.

The green light on the charger does not reflect battery performance. “Ready” simply indicates that the battery is fully charged.

A battery should be replaced when the capacity drops to 70–80%. Most users are unaware of capacity fade until an unforeseen power loss occurs.  Nor should a battery be replaced too soon. The Cadex C7x00 Series battery analyzer enables to keep batteries for their optimal life span.
Ready Light

The C7x00 analyzer test batteries by a discharge/charge cycles or a rapid-test function. A full cycle is the most reliable method but it is not practical for large batteries. Rapid-testing is not available for all batteries. C7x00 Keypad


Li-ion packs often fail due to over-discharge. At about 2.8V/cell, the protection circuit opens and the battery appears dead. Boost activates the circuit and brings the pack back to life. The service lasts a few minutes, but the battery should be full charged.

Reactivating Lithium-ion Batteries


QuickSort™ classifies single Li-ion cell of up to 1500mAh into Good, Low and Poor. Capacity is the leading health indicator; and Cadex’s proprietaryelectrochemical dynamic response method achieves a sort accuracy of 90-95%. Reading internal resistance to estimate battery health is no longer reliable; modern Li-ion keeps low resistance.

  • Tests battery with 40% and higher charge

  • Enables charging if the battery has less than the needed  charge level

Capacity versus Number of Cycles versus Resistance


The target setting allows customizing performance needs to ensure adequate capacity levels for all fleet batteries. If below target, the Auto program reconditions a nickel-based battery with a deep discharge. Recondition reverses the “memory” effect.

  • 90%: Maintains batteries for critical use. Fewer batteries will pass.

  • 80%: Recommended (default) setting.

  • 70%: For less stringent applications. More batteries will pass.

Target Capacity sets battery pass/fail


The C7x00 captures the battery parameters in a unique C-code that is stored in the battery adapter. Each adapter holds 10 C-codes that you can edit. You can also compose your own: The Basic C-code contains the rudimentary information; the Extended C-code revert to default setting unless changed manually. Programmability


The Custom programs turns the C7x000 into a laboratory instrument by allowing 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 not met. Prepare Battery for Storage, Shipment
Custom Programs


This program assists in the selection of battery models and performs incoming inspection. The C7x00 analyzer also offers dynamic stress tests to examine batteries under different load levels. The programs are automated; PC-BatteryShop™ plots and stores the test results. Lifecycle Test


Password protection prevents unauthorized changes of settings. Level 1 allows minor changes and Level 2 inhibits most programming.
