C7400ER C-Series battery analyzer (170 Watts)

Maximize uptime of critical equipment while minimizing battery fleet cost

C7400ER C-Series battery analyzer (170 Watts)
The Cadex C7400ER C-Series is the most powerful of the C7x00 C-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 1.2–36V nominal
Charge/discharge current up to 6A per station
Maximum charge power 75 watts per station
Maximum discharge power 75 watts

The Cadex C7x00 C-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 C-Series battery analyzer enables to keep batteries for their optimal life span.

The C7x00 C-Series 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.

Reactivating Lithium-Ion batteries*
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.

* Of 294 returned batteries, 91% reached 80% and higher capacities; 30% needed Boost

The 30-second rapid-test
QuickSort™ classifies single Li-ion cell of up to 1500mAh into Good, Low and Poor. Capacity is the leading health indicator; and Cadex’s proprietary electrochemical 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

Target capacity sets battery pass/fail
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.

Programmability
The C7x00 C-Series 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.

Custom programs
The Custom programs turns the C7x00 C-Series 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.

Lifecycle test
This program assists in the selection of battery models and performs incoming inspection. The C7x00 C-Series 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.

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